+/**
+ `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ ## Methods to Override
+
+ To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:uploadProgress:downloadProgress:completionHandler:`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+/**
+ `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+ ## Subclassing Notes
+
+ This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
+
+ ## NSURLSession & NSURLSessionTask Delegate Methods
+
+ `AFURLSessionManager` implements the following delegate methods:
+
+ ### `NSURLSessionDelegate`
+
+ - `URLSession:didBecomeInvalidWithError:`
+ - `URLSession:didReceiveChallenge:completionHandler:`
+ - `URLSessionDidFinishEventsForBackgroundURLSession:`
+
+ ### `NSURLSessionTaskDelegate`
+
+ - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
+ - `URLSession:task:didReceiveChallenge:completionHandler:`
+ - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
+ - `URLSession:task:needNewBodyStream:`
+ - `URLSession:task:didCompleteWithError:`
+
+ ### `NSURLSessionDataDelegate`
+
+ - `URLSession:dataTask:didReceiveResponse:completionHandler:`
+ - `URLSession:dataTask:didBecomeDownloadTask:`
+ - `URLSession:dataTask:didReceiveData:`
+ - `URLSession:dataTask:willCacheResponse:completionHandler:`
+
+ ### `NSURLSessionDownloadDelegate`
+
+ - `URLSession:downloadTask:didFinishDownloadingToURL:`
+ - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSCoding Caveats
+
+ - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+
+ ## NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
+ - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+ When implementing an authentication challenge handler, you should check the authentication method first (`challenge.protectionSpace.authenticationMethod `) to decide if you want to handle the authentication challenge yourself or if you want AFNetworking to handle it. If you want AFNetworking to handle the authentication challenge, just return `@(NSURLSessionAuthChallengePerformDefaultHandling)`. For example, you certainly want AFNetworking to handle certificate validation (i.e. authentication method == `NSURLAuthenticationMethodServerTrust`) as defined by the security policy. If you want to handle the challenge yourself, you have four options:
+ 
+ 1. Return `nil` from the authentication challenge handler. You **MUST** call the completion handler with a disposition and credentials yourself. Use this if you need to present a user interface to let the user enter their credentials.
+ 2. Return an `NSError` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSError `. The returned error will be reported in the completion handler of the task. Use this if you need to abort an authentication challenge with a specific error.
+ 3. Return an `NSURLCredential` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSURLCredential`. The returned credentials will be used to fulfil the challenge. Use this when you can get credentials without presenting a user interface.
+ 4. Return an `NSNumber` object wrapping an `NSURLSessionAuthChallengeDisposition`. Supported values are `@(NSURLSessionAuthChallengePerformDefaultHandling)`, `@(NSURLSessionAuthChallengeCancelAuthenticationChallenge)` and `@(NSURLSessionAuthChallengeRejectProtectionSpace)`. You **MUST NOT** call the completion handler when returning an `NSNumber`.
+ 
+ If you return anything else from the authentication challenge handler, an exception will be thrown.

+
+AFNetworking is a delightful networking library for iOS, macOS, watchOS, and tvOS. It's built on top of the [Foundation URL Loading System](https://developer.apple.com/documentation/foundation/url_loading_system), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.
+
+Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.
+
+## How To Get Started
+

+
+## Installation
+AFNetworking supports multiple methods for installing the library in a project.
+
+## Installation with CocoaPods
+
+To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```ruby
+pod 'AFNetworking', '~> 4.0'
+```
+
+### Installation with Swift Package Manager
+
+Once you have your Swift package set up, adding AFNetworking as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/AFNetworking/AFNetworking.git", .upToNextMajor(from: "4.0.0"))
+]
+```
+
+> Note: AFNetworking's Swift package does not include it's UIKit extensions.
+
+### Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate AFNetworking, add the following to your `Cartfile`.
+
+```ogdl
+github "AFNetworking/AFNetworking" ~> 4.0
+```

+
+## Usage
+
+### AFURLSessionManager
+
+`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+#### Creating a Download Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
+    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
+    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
+} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
+    NSLog(@"File downloaded to: %@", filePath);
+}];
+[downloadTask resume];
+```
+
+#### Creating an Upload Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"Success: %@ %@", response, responseObject);
+    }
+}];
+[uploadTask resume];
+```
+
+#### Creating an Upload Task for a Multi-Part Request, with Progress
+
+```objective-c
+NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
+    } error:nil];
+
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
+
+NSURLSessionUploadTask *uploadTask;
+uploadTask = [manager
+              uploadTaskWithStreamedRequest:request
+              progress:^(NSProgress * _Nonnull uploadProgress) {
+                  // This is not called back on the main queue.
+                  // You are responsible for dispatching to the main queue for UI updates
+                  dispatch_async(dispatch_get_main_queue(), ^{
+                      //Update the progress view
+                      [progressView setProgress:uploadProgress.fractionCompleted];
+                  });
+              }
+              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
+                  if (error) {
+                      NSLog(@"Error: %@", error);
+                  } else {
+                      NSLog(@"%@ %@", response, responseObject);
+                  }
+              }];
+
+[uploadTask resume];
+```
+
+#### Creating a Data Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+[dataTask resume];
+```
+
+---
+
+### Request Serialization
+
+Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.
+
+```objective-c
+NSString *URLString = @"http://example.com";
+NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
+```
+
+#### Query String Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
+```
+
+    GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### URL Form Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/x-www-form-urlencoded
+
+    foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### JSON Parameter Encoding
+
+```objective-c
+[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/json
+
+    {"foo": "bar", "baz": [1,2,3]}
+
+---
+
+### Network Reachability Manager
+
+`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
+
+* Do not use Reachability to determine if the original request should be sent.
+	* You should try to send it.
+* You can use Reachability to determine when a request should be automatically retried.
+	* Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
+* Network reachability is a useful tool for determining why a request might have failed.
+	* After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."
+
+See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/).
+
+#### Shared Network Reachability
+
+```objective-c
+[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
+}];
+
+[[AFNetworkReachabilityManager sharedManager] startMonitoring];
+```
+
+---
+
+### Security Policy
+
+`AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections.
+
+Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.
+
+#### Allowing Invalid SSL Certificates
+
+```objective-c
+AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
+manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
+```
+
+---
+

+/**
+ `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a session task has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
+
+ You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
+
+    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
+
+ By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
+
+ See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:
+ http://developer.apple.com/library/iOS/#documentation/UserExperience/Conceptual/MobileHIG/UIElementGuidelines/UIElementGuidelines.html#//apple_ref/doc/uid/TP40006556-CH13-SW44

+
+### Projects using this library
+
+[Add your project to the list here](https://github.com/dzenbot/DZNEmptyDataSet/wiki/Projects-using-DZNEmptyDataSet) and provide a (320px wide) render of the result.
+
+
+### The Empty Data Set Pattern
+Also known as *[Empty State](http://emptystat.es/)* or *[Blank Slate](http://patternry.com/p=blank-slate/)*.
+
+Most applications show lists of content (data sets), which many turn out to be empty at one point, specially for new users with blank accounts. Empty screens create confusion by not being clear about what's going on, if there is an error/bug or if the user is supposed to do something within your app to be able to consume the content.
+
+Please read this very interesting article about [*Designing For The Empty States*](http://tympanus.net/codrops/2013/01/09/designing-for-the-empty-states/).
+
+![Screenshots_Row1](https://raw.githubusercontent.com/dzenbot/UITableView-DataSet/master/Examples/Applications/Screenshots/Screenshots_row1.png)
+![Screenshots_Row2](https://raw.githubusercontent.com/dzenbot/UITableView-DataSet/master/Examples/Applications/Screenshots/Screenshots_row2.png)
+(*These are real life examples, available in the 'Applications' sample project*)
+
+**[Empty Data Sets](http://pttrns.com/?did=1&scid=30)** are helpful for:
+* Avoiding white-screens and communicating to your users why the screen is empty.
+* Calling to action (particularly as an onboarding process).
+* Avoiding other interruptive mechanisms like showing error alerts.
+* Being consistent and improving the user experience.
+* Delivering a brand presence.
+
+
+### Features
+* Compatible with UITableView and UICollectionView. Also compatible with UISearchDisplayController and UIScrollView.
+* Gives multiple possibilities of layout and appearance, by showing an image and/or title label and/or description label and/or button.
+* Uses NSAttributedString for easier appearance customisation.
+* Uses auto-layout to automagically center the content to the tableview, with auto-rotation support. Also accepts custom vertical and horizontal alignment.
+* Background color customisation.
+* Allows tap gesture on the whole tableview rectangle (useful for resigning first responder or similar actions).
+* For more advanced customisation, it allows a custom view.
+* Compatible with Storyboard.
+* Compatible with iOS 6 or later.
+* Compatible with iPhone and iPad.
+* **App Store ready**
+
+This library has been designed in a way where you won't need to extend UITableView or UICollectionView class. It will still work when using UITableViewController or UICollectionViewController.
+By just conforming to DZNEmptyDataSetSource & DZNEmptyDataSetDelegate, you will be able to fully customize the content and appearance of the empty states for your application.
+
+
+## Installation
+
+Available in [CocoaPods](http://cocoapods.org/?q=DZNEmptyDataSet)
+```ruby
+pod 'DZNEmptyDataSet'
+```
+
+To integrate DZNEmptyDataSet into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```ruby
+github "dzenbot/DZNEmptyDataSet"
+```
+
+
+## How to use
+For complete documentation, [visit CocoaPods' auto-generated doc](http://cocoadocs.org/docsets/DZNEmptyDataSet/)
+
+### Import
+```objc
+#import "UIScrollView+EmptyDataSet.h"
+```
+Unless you are importing as a framework, then do:
+```objc
+#import "<DZNEmptyDataSet/UIScrollView+EmptyDataSet.h>"
+```
+
+### Protocol Conformance
+Conform to datasource and/or delegate.
+```objc
+@interface MainViewController : UITableViewController <DZNEmptyDataSetSource, DZNEmptyDataSetDelegate>
+
+- (void)viewDidLoad
+{
+    [super viewDidLoad];
+
+    self.tableView.emptyDataSetSource = self;
+    self.tableView.emptyDataSetDelegate = self;
+    
+    // A little trick for removing the cell separators
+    self.tableView.tableFooterView = [UIView new];
+}
+```
+
+### Data Source Implementation
+Return the content you want to show on the empty state, and take advantage of NSAttributedString features to customise the text appearance.
+
+The image for the empty state:
+```objc
+- (UIImage *)imageForEmptyDataSet:(UIScrollView *)scrollView
+{
+    return [UIImage imageNamed:@"empty_placeholder"];
+}
+```
+
+The image view animation
+```objc
+- (CAAnimation *)imageAnimationForEmptyDataSet:(UIScrollView *)scrollView
+{
+    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath: @"transform"];
+    
+    animation.fromValue = [NSValue valueWithCATransform3D:CATransform3DIdentity];
+    animation.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI_2, 0.0, 0.0, 1.0)];
+    
+    animation.duration = 0.25;
+    animation.cumulative = YES;
+    animation.repeatCount = MAXFLOAT;
+    
+    return animation;
+}
+```
+
+The attributed string for the title of the empty state:
+```objc
+- (NSAttributedString *)titleForEmptyDataSet:(UIScrollView *)scrollView
+{
+    NSString *text = @"Please Allow Photo Access";
+    
+    NSDictionary *attributes = @{NSFontAttributeName: [UIFont boldSystemFontOfSize:18.0f],
+                                 NSForegroundColorAttributeName: [UIColor darkGrayColor]};
+    
+    return [[NSAttributedString alloc] initWithString:text attributes:attributes];
+}
+```
+
+The attributed string for the description of the empty state:
+```objc
+- (NSAttributedString *)descriptionForEmptyDataSet:(UIScrollView *)scrollView
+{
+    NSString *text = @"This allows you to share photos from your library and save photos to your camera roll.";
+    
+    NSMutableParagraphStyle *paragraph = [NSMutableParagraphStyle new];
+    paragraph.lineBreakMode = NSLineBreakByWordWrapping;
+    paragraph.alignment = NSTextAlignmentCenter;
+    
+    NSDictionary *attributes = @{NSFontAttributeName: [UIFont systemFontOfSize:14.0f],
+                                 NSForegroundColorAttributeName: [UIColor lightGrayColor],
+                                 NSParagraphStyleAttributeName: paragraph};
+                                 
+    return [[NSAttributedString alloc] initWithString:text attributes:attributes];                      
+}
+```
+
+The attributed string to be used for the specified button state:
+```objc
+- (NSAttributedString *)buttonTitleForEmptyDataSet:(UIScrollView *)scrollView forState:(UIControlState)state
+{
+    NSDictionary *attributes = @{NSFontAttributeName: [UIFont boldSystemFontOfSize:17.0f]};
+
+    return [[NSAttributedString alloc] initWithString:@"Continue" attributes:attributes];
+}
+```
+
+or the image to be used for the specified button state:
+```objc
+- (UIImage *)buttonImageForEmptyDataSet:(UIScrollView *)scrollView forState:(UIControlState)state
+{
+    return [UIImage imageNamed:@"button_image"];
+}
+```
+
+The background color for the empty state:
+```objc
+- (UIColor *)backgroundColorForEmptyDataSet:(UIScrollView *)scrollView
+{
+    return [UIColor whiteColor];
+}
+```
+
+If you need a more complex layout, you can return a custom view instead:
+```objc
+- (UIView *)customViewForEmptyDataSet:(UIScrollView *)scrollView
+{
+    UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
+    [activityView startAnimating];
+    return activityView;
+}
+```
+
+Additionally, you can also adjust the vertical alignment of the content view (ie: useful when there is tableHeaderView visible):
+```objc
+- (CGFloat)verticalOffsetForEmptyDataSet:(UIScrollView *)scrollView
+{
+    return -self.tableView.tableHeaderView.frame.size.height/2.0f;
+}
+```
+
+Finally, you can separate components from each other (default separation is 11 pts):
+```objc
+- (CGFloat)spaceHeightForEmptyDataSet:(UIScrollView *)scrollView
+{
+    return 20.0f;
+}
+```
+
+
+### Delegate Implementation
+Return the behaviours you would expect from the empty states, and receive the user events.
+
+Asks to know if the empty state should be rendered and displayed (Default is YES) :
+```objc
+- (BOOL)emptyDataSetShouldDisplay:(UIScrollView *)scrollView
+{
+    return YES;
+}
+```
+
+Asks for interaction permission (Default is YES) :
+```objc
+- (BOOL)emptyDataSetShouldAllowTouch:(UIScrollView *)scrollView
+{
+    return YES;
+}
+```
+
+Asks for scrolling permission (Default is NO) :
+```objc
+- (BOOL)emptyDataSetShouldAllowScroll:(UIScrollView *)scrollView
+{
+    return YES;
+}
+```
+
+Asks for image view animation permission (Default is NO) :
+```objc
+- (BOOL) emptyDataSetShouldAllowImageViewAnimate:(UIScrollView *)scrollView
+{
+    return YES;
+}
+```
+
+Notifies when the dataset view was tapped:
+```objc
+- (void)emptyDataSet:(UIScrollView *)scrollView didTapView:(UIView *)view
+{
+    // Do something
+}
+```
+
+Notifies when the data set call to action button was tapped:
+```objc
+- (void)emptyDataSet:(UIScrollView *)scrollView didTapButton:(UIButton *)button
+{
+    // Do something
+}
+```
+
+### Refresh layout
+If you need to refresh the empty state layout, simply call:
+
+```objc
+[self.tableView reloadData];
+```
+or
+```objc
+[self.collectionView reloadData];
+```
+depending of which you are using.
+
+### Force layout update
+You can also call `[self.tableView reloadEmptyDataSet]` to invalidate the current empty state layout and trigger a layout update, bypassing `-reloadData`. This might be useful if you have a lot of logic on your data source that you want to avoid calling, when not needed. `[self.scrollView reloadEmptyDataSet]` is the only way to refresh content when using with UIScrollView.
+
+
+## Sample projects
+
+#### Applications
+This project replicates several popular application's empty states (~20) with their exact content and appearance, such as Airbnb, Dropbox, Facebook, Foursquare, and many others. See how easy and flexible it is to customize the appearance of your empty states. You can also use this project as a playground to test things.
+
+#### Countries
+This project shows a list of the world countries loaded from CoreData. It uses NSFecthedResultController for filtering search. When searching and no content is matched, a simple empty state is shown. See how to interact between the UITableViewDataSource and the DZNEmptyDataSetSource protocols, while using a typical CoreData stack.
+
+#### Colors
+This project is a simple example of how this library also works with UICollectionView and UISearchDisplayController, while using Storyboards.

+# Introduction
+You can inspect and modify views in iOS app via Lookin, just like UI Inspector in Xcode, or another app called Reveal.
+
+Official Website：https://lookin.work/
+
+# Integration Guide
+To use Lookin macOS app, you need to integrate LookinServer (iOS Framework of Lookin) into your iOS project.
+
+> **Warning**
+> 1. Never integrate LookinServer in Release building configuration.
+> 2. Do not use versions earlier than 1.0.6, as it contains a critical bug that could lead to online incidents in your project: https://qxh1ndiez2w.feishu.cn/wiki/Z9SpwT7zWiqvYvkBe7Lc6Disnab
+
+## via CocoaPods:

+# 简介
+Lookin 可以查看与修改 iOS App 里的 UI 对象，类似于 Xcode 自带的 UI Inspector 工具，或另一款叫做 Reveal 的软件。
+
+官网：https://lookin.work/
+
+# 安装 LookinServer Framework
+如果这是你的 iOS 项目第一次使用 Lookin，则需要先把 LookinServer 这款 iOS Framework 集成到你的 iOS 项目中。
+
+> **Warning**
+> 
+> 1. 不要在 AppStore 模式下集成 LookinServer。
+> 2. 不要使用早于 1.0.6 的版本，因为它包含一个严重 Bug，可能导致线上事故: https://qxh1ndiez2w.feishu.cn/wiki/Z9SpwT7zWiqvYvkBe7Lc6Disnab
