-
-**Masonry is still actively maintained, we are committed to fixing bugs and merging good quality PRs from the wider community. However if you're using Swift in your project, we recommend using [SnapKit](https://github.com/SnapKit/SnapKit) as it provides better type safety with a simpler API.**
-
-Masonry is a light-weight layout framework which wraps AutoLayout with a nicer syntax. Masonry has its own layout DSL which provides a chainable way of describing your NSLayoutConstraints which results in layout code that is more concise and readable.
-Masonry supports iOS and Mac OS X.
-
-For examples take a look at the **Masonry iOS Examples** project in the Masonry workspace. You will need to run `pod install` after downloading.
-
-## What's wrong with NSLayoutConstraints?
-
-Under the hood Auto Layout is a powerful and flexible way of organising and laying out your views. However creating constraints from code is verbose and not very descriptive.
-Imagine a simple example in which you want to have a view fill its superview but inset by 10 pixels on every side
-```obj-c
-UIView *superview = self.view;
-
-UIView *view1 = [[UIView alloc] init];
-view1.translatesAutoresizingMaskIntoConstraints = NO;
-view1.backgroundColor = [UIColor greenColor];
-[superview addSubview:view1];
-
-UIEdgeInsets padding = UIEdgeInsetsMake(10, 10, 10, 10);
-
-[superview addConstraints:@[
-
-    //view1 constraints
-    [NSLayoutConstraint constraintWithItem:view1
-                                 attribute:NSLayoutAttributeTop
-                                 relatedBy:NSLayoutRelationEqual
-                                    toItem:superview
-                                 attribute:NSLayoutAttributeTop
-                                multiplier:1.0
-                                  constant:padding.top],
-
-    [NSLayoutConstraint constraintWithItem:view1
-                                 attribute:NSLayoutAttributeLeft

-                                multiplier:1.0
-                                  constant:padding.left],
-
-    [NSLayoutConstraint constraintWithItem:view1
-                                 attribute:NSLayoutAttributeBottom

-                                 attribute:NSLayoutAttributeBottom
-                                multiplier:1.0
-                                  constant:-padding.bottom],
-
-    [NSLayoutConstraint constraintWithItem:view1
-                                 attribute:NSLayoutAttributeRight
-                                 relatedBy:NSLayoutRelationEqual

-                                  constant:-padding.right],
-
- ]];
-```
-Even with such a simple example the code needed is quite verbose and quickly becomes unreadable when you have more than 2 or 3 views.
-Another option is to use Visual Format Language (VFL), which is a bit less long winded.
-However the ASCII type syntax has its own pitfalls and its also a bit harder to animate as `NSLayoutConstraint constraintsWithVisualFormat:` returns an array.
-
-## Prepare to meet your Maker!
-
-Heres the same constraints created using MASConstraintMaker
-
-```obj-c
-UIEdgeInsets padding = UIEdgeInsetsMake(10, 10, 10, 10);
-
-[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
-    make.top.equalTo(superview.mas_top).with.offset(padding.top); //with is an optional semantic filler
-    make.left.equalTo(superview.mas_left).with.offset(padding.left);
-    make.bottom.equalTo(superview.mas_bottom).with.offset(-padding.bottom);
-    make.right.equalTo(superview.mas_right).with.offset(-padding.right);
-}];
-```
-Or even shorter
-
-```obj-c
-[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
-    make.edges.equalTo(superview).with.insets(padding);
-}];
-```
-
-Also note in the first example we had to add the constraints to the superview `[superview addConstraints:...`.
-Masonry however will automagically add constraints to the appropriate view.
-
-Masonry will also call `view1.translatesAutoresizingMaskIntoConstraints = NO;` for you.
-
-## Not all things are created equal
-
-> `.equalTo` equivalent to **NSLayoutRelationEqual**
-
-> `.lessThanOrEqualTo` equivalent to **NSLayoutRelationLessThanOrEqual**
-
-> `.greaterThanOrEqualTo` equivalent to **NSLayoutRelationGreaterThanOrEqual**
-
-These three equality constraints accept one argument which can be any of the following:
-
-#### 1. MASViewAttribute
-
-```obj-c
-make.centerX.lessThanOrEqualTo(view2.mas_left);
-```
-
-MASViewAttribute           |  NSLayoutAttribute
--------------------------  |  --------------------------
-view.mas_left              |  NSLayoutAttributeLeft
-view.mas_right             |  NSLayoutAttributeRight
-view.mas_top               |  NSLayoutAttributeTop
-view.mas_bottom            |  NSLayoutAttributeBottom
-view.mas_leading           |  NSLayoutAttributeLeading
-view.mas_trailing          |  NSLayoutAttributeTrailing
-view.mas_width             |  NSLayoutAttributeWidth
-view.mas_height            |  NSLayoutAttributeHeight
-view.mas_centerX           |  NSLayoutAttributeCenterX
-view.mas_centerY           |  NSLayoutAttributeCenterY
-view.mas_baseline          |  NSLayoutAttributeBaseline
-
-#### 2. UIView/NSView
-
-if you want view.left to be greater than or equal to label.left :
-```obj-c
-//these two constraints are exactly the same
-make.left.greaterThanOrEqualTo(label);
-make.left.greaterThanOrEqualTo(label.mas_left);
-```
-
-#### 3. NSNumber
-
-Auto Layout allows width and height to be set to constant values.
-if you want to set view to have a minimum and maximum width you could pass a number to the equality blocks:
-```obj-c
-//width >= 200 && width <= 400
-make.width.greaterThanOrEqualTo(@200);
-make.width.lessThanOrEqualTo(@400)
-```
-
-However Auto Layout does not allow alignment attributes such as left, right, centerY etc to be set to constant values.
-So if you pass a NSNumber for these attributes Masonry will turn these into constraints relative to the view&rsquo;s superview ie:
-```obj-c
-//creates view.left = view.superview.left + 10
-make.left.lessThanOrEqualTo(@10)
-```
-
-Instead of using NSNumber, you can use primitives and structs to build your constraints, like so:
-```obj-c
-make.top.mas_equalTo(42);
-make.height.mas_equalTo(20);
-make.size.mas_equalTo(CGSizeMake(50, 100));
-make.edges.mas_equalTo(UIEdgeInsetsMake(10, 0, 10, 0));
-make.left.mas_equalTo(view).mas_offset(UIEdgeInsetsMake(10, 0, 10, 0));
-```
-
-By default, macros which support [autoboxing](https://en.wikipedia.org/wiki/Autoboxing#Autoboxing) are prefixed with `mas_`. Unprefixed versions are available by defining `MAS_SHORTHAND_GLOBALS` before importing Masonry.
-
-#### 4. NSArray
-
-An array of a mixture of any of the previous types
-```obj-c
-make.height.equalTo(@[view1.mas_height, view2.mas_height]);
-make.height.equalTo(@[view1, view2]);
-make.left.equalTo(@[view1, @100, view3.right]);
-````
-
-## Learn to prioritize
-
-> `.priority` allows you to specify an exact priority
-
-> `.priorityHigh` equivalent to **UILayoutPriorityDefaultHigh**
-
-> `.priorityMedium` is half way between high and low
-
-> `.priorityLow` equivalent to **UILayoutPriorityDefaultLow**
-
-Priorities are can be tacked on to the end of a constraint chain like so:
-```obj-c
-make.left.greaterThanOrEqualTo(label.mas_left).with.priorityLow();
-
-make.top.equalTo(label.mas_top).with.priority(600);
-```
-
-## Composition, composition, composition
-
-Masonry also gives you a few convenience methods which create multiple constraints at the same time. These are called MASCompositeConstraints
-
-#### edges
-
-```obj-c
-// make top, left, bottom, right equal view2
-make.edges.equalTo(view2);
-
-// make top = superview.top + 5, left = superview.left + 10,
-//      bottom = superview.bottom - 15, right = superview.right - 20
-make.edges.equalTo(superview).insets(UIEdgeInsetsMake(5, 10, 15, 20))
-```
-
-#### size
-
-```obj-c
-// make width and height greater than or equal to titleLabel
-make.size.greaterThanOrEqualTo(titleLabel)
-
-// make width = superview.width + 100, height = superview.height - 50
-make.size.equalTo(superview).sizeOffset(CGSizeMake(100, -50))
-```
-
-#### center
-```obj-c
-// make centerX and centerY = button1
-make.center.equalTo(button1)
-
-// make centerX = superview.centerX - 5, centerY = superview.centerY + 10
-make.center.equalTo(superview).centerOffset(CGPointMake(-5, 10))
-```
-
-You can chain view attributes for increased readability:
-
-```obj-c
-// All edges but the top should equal those of the superview
-make.left.right.and.bottom.equalTo(superview);
-make.top.equalTo(otherView);
-```
-
-## Hold on for dear life
-
-Sometimes you need modify existing constraints in order to animate or remove/replace constraints.
-In Masonry there are a few different approaches to updating constraints.
-
-#### 1. References
-You can hold on to a reference of a particular constraint by assigning the result of a constraint make expression to a local variable or a class property.
-You could also reference multiple constraints by storing them away in an array.
-
-```obj-c
-// in public/private interface
-@property (nonatomic, strong) MASConstraint *topConstraint;
-
-...
-
-// when making constraints
-[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
-    self.topConstraint = make.top.equalTo(superview.mas_top).with.offset(padding.top);
-    make.left.equalTo(superview.mas_left).with.offset(padding.left);
-}];
-
-...
-// then later you can call
-[self.topConstraint uninstall];
-```
-
-#### 2. mas_updateConstraints
-Alternatively if you are only updating the constant value of the constraint you can use the convience method `mas_updateConstraints` instead of `mas_makeConstraints`
-
-```obj-c
-// this is Apple's recommended place for adding/updating constraints
-// this method can get called multiple times in response to setNeedsUpdateConstraints
-// which can be called by UIKit internally or in your code if you need to trigger an update to your constraints
-- (void)updateConstraints {
-    [self.growingButton mas_updateConstraints:^(MASConstraintMaker *make) {
-        make.center.equalTo(self);
-        make.width.equalTo(@(self.buttonSize.width)).priorityLow();
-        make.height.equalTo(@(self.buttonSize.height)).priorityLow();
-        make.width.lessThanOrEqualTo(self);
-        make.height.lessThanOrEqualTo(self);
-    }];
-
-    //according to apple super should be called at end of method
-    [super updateConstraints];
-}
-```
-
-### 3. mas_remakeConstraints
-`mas_updateConstraints` is useful for updating a set of constraints, but doing anything beyond updating constant values can get exhausting. That's where `mas_remakeConstraints` comes in.
-
-`mas_remakeConstraints` is similar to `mas_updateConstraints`, but instead of updating constant values, it will remove all of its constraints before installing them again. This lets you provide different constraints without having to keep around references to ones which you want to remove.
-
-```obj-c
-- (void)changeButtonPosition {
-    [self.button mas_remakeConstraints:^(MASConstraintMaker *make) {
-        make.size.equalTo(self.buttonSize);
-
-        if (topLeft) {
-        	make.top.and.left.offset(10);

-    }];
-}

-
-You can find more detailed examples of all three approaches in the **Masonry iOS Examples** project.
-
-## When the ^&*!@ hits the fan!
-
-Laying out your views doesn't always goto plan. So when things literally go pear shaped, you don't want to be looking at console output like this:
-
-```obj-c
-Unable to simultaneously satisfy constraints.....blah blah blah....
-(
-    "<NSLayoutConstraint:0x7189ac0 V:[UILabel:0x7186980(>=5000)]>",
-    "<NSAutoresizingMaskLayoutConstraint:0x839ea20 h=--& v=--& V:[MASExampleDebuggingView:0x7186560(416)]>",
-    "<NSLayoutConstraint:0x7189c70 UILabel:0x7186980.bottom == MASExampleDebuggingView:0x7186560.bottom - 10>",
-    "<NSLayoutConstraint:0x7189560 V:|-(1)-[UILabel:0x7186980]   (Names: '|':MASExampleDebuggingView:0x7186560 )>"
-)
-
-Will attempt to recover by breaking constraint
-<NSLayoutConstraint:0x7189ac0 V:[UILabel:0x7186980(>=5000)]>
-```
-
-Masonry adds a category to NSLayoutConstraint which overrides the default implementation of `- (NSString *)description`.
-Now you can give meaningful names to views and constraints, and also easily pick out the constraints created by Masonry.
-
-which means your console output can now look like this:
-
-```obj-c
-Unable to simultaneously satisfy constraints......blah blah blah....
-(
-    "<NSAutoresizingMaskLayoutConstraint:0x8887740 MASExampleDebuggingView:superview.height == 416>",
-    "<MASLayoutConstraint:ConstantConstraint UILabel:messageLabel.height >= 5000>",
-    "<MASLayoutConstraint:BottomConstraint UILabel:messageLabel.bottom == MASExampleDebuggingView:superview.bottom - 10>",
-    "<MASLayoutConstraint:ConflictingConstraint[0] UILabel:messageLabel.top == MASExampleDebuggingView:superview.top + 1>"
-)
-
-Will attempt to recover by breaking constraint
-<MASLayoutConstraint:ConstantConstraint UILabel:messageLabel.height >= 5000>
-```
-
-For an example of how to set this up take a look at the **Masonry iOS Examples** project in the Masonry workspace.
-
-## Where should I create my constraints?
-
-```objc
-@implementation DIYCustomView
-
-- (id)init {
-    self = [super init];
-    if (!self) return nil;
-
-    // --- Create your views here ---
-    self.button = [[UIButton alloc] init];
-
-    return self;
-}
-
-// tell UIKit that you are using AutoLayout
-+ (BOOL)requiresConstraintBasedLayout {
-    return YES;
-}
-
-// this is Apple's recommended place for adding/updating constraints
-- (void)updateConstraints {
-
-    // --- remake/update constraints here
-    [self.button remakeConstraints:^(MASConstraintMaker *make) {
-        make.width.equalTo(@(self.buttonSize.width));
-        make.height.equalTo(@(self.buttonSize.height));
-    }];
-    
-    //according to apple super should be called at end of method
-    [super updateConstraints];
-}
-
-- (void)didTapButton:(UIButton *)button {
-    // --- Do your changes ie change variables that affect your layout etc ---
-    self.buttonSize = CGSize(200, 200);
-
-    // tell constraints they need updating
-    [self setNeedsUpdateConstraints];
-}
-
-@end
-```
-
-## Installation
-Use the [orsome](http://www.youtube.com/watch?v=YaIZF8uUTtk) [CocoaPods](http://github.com/CocoaPods/CocoaPods).
-
-In your Podfile
->`pod 'Masonry'`
-
-If you want to use masonry without all those pesky 'mas_' prefixes. Add #define MAS_SHORTHAND to your prefix.pch before importing Masonry
->`#define MAS_SHORTHAND`
-
-Get busy Masoning
->`#import "Masonry.h"`
-
-## Code Snippets
-
-Copy the included code snippets to ``~/Library/Developer/Xcode/UserData/CodeSnippets`` to write your masonry blocks at lightning speed!
-
-`mas_make` -> ` [<#view#> mas_makeConstraints:^(MASConstraintMaker *make) {
-     <#code#>
- }];`
-
-`mas_update` -> ` [<#view#> mas_updateConstraints:^(MASConstraintMaker *make) {
-     <#code#>
- }];`
-
-`mas_remake` -> ` [<#view#> mas_remakeConstraints:^(MASConstraintMaker *make) {
-     <#code#>
- }];`
-
-## Features
-* Not limited to subset of Auto Layout. Anything NSLayoutConstraint can do, Masonry can do too!
-* Great debug support, give your views and constraints meaningful names.
-* Constraints read like sentences.
-* No crazy macro magic. Masonry won't pollute the global namespace with macros.
-* Not string or dictionary based and hence you get compile time checking.
-
-## TODO
-* Eye candy
-* Mac example project
-* More tests and examples

+
+### 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

+
+### 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:
+### Swift Project
+`pod 'LookinServer', :subspecs => ['Swift'], :configurations => ['Debug']`
+### Objective-C Project
+`pod 'LookinServer', :configurations => ['Debug']`
+## via Swift Package Manager:
+`https://github.com/QMUI/LookinServer/`

+# 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
