# LYEmptyView
|
||||
不需要遵循协议，不需要设置代理，不需要实现代理方法，只需这一句代码，就可为一个UITableViwe/UICollectionView集成空白页面占位图。<br>`self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];`
|
||||
|
||||
#### 注意点:
|
||||
#### 1.除UITableViwe/UICollectionView外，这些View(包括UIScrollView)没有DataSource，代码层面无法判断有无数据，需手动管理显示隐藏，调用示例请移步示例8
|
||||
|
||||
| 特点 | 描述 |
|
||||
| ---------- | -----------|
|
||||
| 与项目完全解耦 | 在需要集成的界面中加入一行代码即可集成，与原代码没有一点耦合度 |
|
||||
| 0学习成本 | 无需关心视图的显示隐藏时机，只需加入一行代码即可，框架监听了系统刷新UI的方法，其内部计算后自动进行显示隐藏 |
|
||||
| 调用简单 | 利用分类+runtime，使调用非常简便 |
|
||||
| 高度自定义 | 利用继承特性，可对框架进行二次封装，使自定义更简便 |
|
||||
| 支持全部的刷新方法 | reload...、insert...、delete...等方法。你的项目中调用这些刷新方法时，该框架都会自动根据DataSource自动进行计算判断是否显示emptyView |

## <a id="效果展示"></a>一、效果展示
|
||||
|
||||
|
||||
|
||||
## <a id="集成方式"></a>二、集成方式
|
||||
|
||||
1.Cocoapods方式集成: `pod 'LYEmptyView'`<br>
|
||||
使用时导入头文件 `#import <LYEmptyView/LYEmptyViewHeader.h>`
|
||||
<br><br>
|
||||
2.手动下载集成: 将LYEmptyView文件夹，导入你的工程<br>
|
||||
使用时导入头文件：`#import "LYEmptyViewHeader.h"`
|
||||
|
||||
|
||||
## <a id="使用参考示例"></a>三、使用参考示例
|
||||
|
||||
### <a id="一行代码集成空内容视图"></a>1.一行代码集成空内容视图
|
||||
|
||||
```Objective-C
|
||||
//框架方法
|
||||
self.tableView.ly_emptyView = [LYEmptyView emptyViewWithImageStr:@"noData"
|
||||
titleStr:@"暂无数据，点击重新加载"
|
||||
detailStr:@""];
|
||||
```
|
||||
|
||||
PS:可对库进行二次封装，调用更简洁（二次封装方法在下面的示例5中会讲到）
|
||||
```Objective-C
|
||||
//二次封装方法，调用简洁
|
||||
self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];
|
||||
```
|
||||
|
||||
完全低耦合，在你的项目中加入这一行代码就可集成<br>
|
||||
不管项目中是reloadData方法刷UI还是insert、delete等方式刷UI,不需做其他任何操作，只需这一行代码就可实现以下效果
|
||||
|
||||
|
||||
|
||||
### <a id="自由选择空内容元素"></a>2.自由选择空内容元素
|
||||
```Objective-C
|
||||
交互事件可选择SEL或block方式
|
||||
self.tableView.ly_emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData"
|
||||
titleStr:@"无数据"
|
||||
detailStr:@"请稍后再试!"
|
||||
btnTitleStr:@"重新加载"
|
||||
target:target
|
||||
action:action];
|
||||
self.tableView.ly_emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData"
|
||||
titleStr:@""
|
||||
detailStr:@""
|
||||
btnTitleStr:@""
|
||||
btnClickBlock:^{}];
|
||||
// imageStr : 占位图片
|
||||
// titleStr : 标题
|
||||
// detailStr : 详细描述
|
||||
// btnTitleStr : 按钮标题
|
||||
```
|
||||
框架提供四个元素，传入相应元素的字符串即可显示对应元素（按钮的显示前提是传入target，action或btnClickBlock）
|
||||
可根据项目需求，自由进行组合，如下只展示了部分组合效果
|
||||
|
||||
|
||||
|
||||
### <a id="自定义空内容元素"></a>3.自定义空内容元素
|
||||
特殊情况下，如果空内容状态布局不满足需求时，可进行自定义<br>
|
||||
通过方法` + (instancetype)emptyViewWithCustomView:(UIView *)customView;`<br>
|
||||
传入一个View 即可创建一个自定义的emptyView
|
||||
```Objective-C
|
||||
self.tableView.ly_emptyView = [LYEmptyView emptyViewWithCustomView:customView];
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
### <a id="自定义元素的UI样式"></a>4.自定义元素的UI样式
|
||||
这里自定义UI样式需要很多代码，别担心，在示例5中会讲解二次封装的方式，封装后调用时就只需要一行代码了 ^_^
|
||||
```Objective-C
|
||||
//初始化一个emptyView
|
||||
LYEmptyView *emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData"
|
||||
titleStr:@"无数据"
|
||||
detailStr:@"请稍后再试!"
|
||||
btnTitleStr:@"重新加载"
|
||||
btnClickBlock:^{}];
|
||||
//元素竖直方向的间距
|
||||
emptyView.subViewMargin = 20.f;
|
||||
//标题颜色
|
||||
emptyView.titleLabTextColor = MainColor(90, 180, 160);
|
||||
//描述字体
|
||||
emptyView.detailLabFont = [UIFont systemFontOfSize:17];
|
||||
//按钮背景色
|
||||
emptyView.actionBtnBackGroundColor = MainColor(90, 180, 160);
|
||||
|
||||
//设置空内容占位图
|
||||
self.tableView.ly_emptyView = emptyView;
|
||||
```
|
||||
>这里只列举了一些常用的属性，更多属性请到LYEmptyView.h查看
|
||||
|
||||
|
||||
### <a id="二次封装"></a>5.二次封装
|
||||
第4小节的示例代码，修改emptyView的样式需要一个个属性单独去改，如果项目中每个界面都这么写就显得很麻烦，而且不易维护<br>
|
||||
解决办法是对库进行二次封装，二次封装后，对UI样式单独管理，方便维护<br>
|
||||
|
||||
##### 1)新建一个类继承自LYEmptyView，例如demo中的MyDIYEmpty
|
||||
##### 2)重写`- (void)prepare` 方法，并修改想要改变的元素的UI样式
|
||||
```Objective-C
|
||||
- (void)prepare{
|
||||
[super prepare];
|
||||
|
||||
self.titleLabFont = [UIFont systemFontOfSize:25];
|
||||
self.titleLabTextColor = MainColor(90, 180, 160);
|
||||
|
||||
self.detailLabFont = [UIFont systemFontOfSize:17];
|
||||
self.detailLabTextColor = MainColor(180, 120, 90);
|
||||
self.detailLabMaxLines = 5;
|
||||
|
||||
self.actionBtnBackGroundColor = MainColor(90, 180, 160);
|
||||
self.actionBtnTitleColor = [UIColor whiteColor];
|
||||
}
|
||||
```
|
||||
操作上面的两步就可实现对样式的单独管理<br>
|
||||
调用方法不变，只是调用的类变成了MYDiyEmpty
|
||||
```Objective-C
|
||||
self.tableView.ly_emptyView = [MyDIYEmpty emptyActionViewWithImageStr:@"noData"
|
||||
titleStr:@"无数据"
|
||||
detailStr:@"请稍后再试!"
|
||||
btnTitleStr:@"重新加载"
|
||||
btnClickBlock:^{}];
|
||||
```
|
||||
##### 3)进一步封装显示的元素内容，比如无数据状态图、无网络状态图<br>
|
||||
在MyDIYEmpty.h定义方法`+ (instancetype)diyNoDataEmpty;`<br>
|
||||
在MyDIYEmpty.m实现方法
|
||||
```Objective-C
|
||||
+ (instancetype)diyNoDataEmpty{
|
||||
return [MyDIYEmpty emptyViewWithImageStr:@"nodata"
|
||||
titleStr:@"暂无数据"
|
||||
detailStr:@"请检查您的网络连接是否正确!"];
|
||||
}
|
||||
```
|
||||
>经过3步封装，自定义了UI样式，使管理更方便，使调用更简洁<br>
|
||||
self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];
|
||||
|
||||
### <a id="延迟显示emptyView"></a>6.延迟显示emptyView
|
||||
如示例1图，框架自动根据DataSource计算是否显示emptyView，在空页面发起网络请求时，DataSource肯定为空，会自动显示emptyView，有的产品需求可能不希望这样，希望发起请求时暂时隐藏emptyView。
|
||||
本框架提供了两个方法可实现此需求，两个方法都是scrollView的分类，调用非常方便
|
||||
```Objective-C
|
||||
/**
|
||||
一般用于开始请求网络时调用，ly_startLoading调用时会暂时隐藏emptyView
|
||||
当调用ly_endLoading方法时，ly_endLoading方法内部会根据当前的tableView/collectionView的
|
||||
DataSource来自动判断是否显示emptyView
|
||||
*/
|
||||
- (void)ly_startLoading;
|
||||
|
||||
/**
|
||||
在想要刷新emptyView状态时调用
|
||||
注意:ly_endLoading 的调用时机，有刷新UI的地方一定要等到刷新UI的方法之后调用，
|
||||
因为只有刷新了UI，view的DataSource才会更新，故调用此方法才能正确判断是否有内容。
|
||||
*/
|
||||
- (void)ly_endLoading;
|
||||
```
|
||||
|
||||
*注意点:使用这两个方法，请先将emptyView的autoShowEmptyView属性置为NO，关闭自动显隐
|
||||
|
||||
以下是调用示例（具体细节可参看demo中的demo2）
|
||||
```Objective-C
|
||||
//1.先设置样式
|
||||
self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];
|
||||
//2.关闭自动显隐（此步可封装进自定义类中，相关调用就可省去这步）
|
||||
self.tableView.ly_emptyView.autoShowEmptyView = NO;
|
||||
//3.网络请求时调用
|
||||
[self.tableView ly_startLoading];
|
||||
//4.刷新UI时调用（保证在刷新UI后调用）
|
||||
[self.tableView ly_endLoading];
|
||||
```
|
||||
|
||||
|
||||
|
||||
### <a id="特殊需求，手动控制emptyView的显示隐藏"></a>7.特殊需求，手动控制emptyView的显示隐藏
|
||||
在某些特殊界面下，有的tableView/collectionView有固定的一些死数据，其它的数据根据网络加载，这时根据以上的示例方法可能达不到这需求。<br>
|
||||
本框架提供另外的两个方法来解决这个问题。
|
||||
|
||||
```Objective-C
|
||||
/**
|
||||
手动调用显示emptyView
|
||||
*/
|
||||
- (void)ly_showEmptyView;
|
||||
|
||||
/**
|
||||
手动调用隐藏emptyView
|
||||
*/
|
||||
- (void)ly_hideEmptyView;
|
||||
```
|
||||
|
||||
*注意点:使用这两个方法，请先将emptyView的autoShowEmptyView属性置为NO，关闭自动显隐
|
||||
|
||||
以下是调用示例（具体细节可参看demo中的demo4）
|
||||
```Objective-C
|
||||
//1.先设置样式
|
||||
self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];
|
||||
//2.关闭自动显隐（此步可封装进自定义类中，相关调用就可省去这步）
|
||||
self.tableView.ly_emptyView.autoShowEmptyView = NO;
|
||||
//3.显示emptyView
|
||||
[self.tableView ly_showEmptyView];
|
||||
//4.隐藏emptyView
|
||||
[self.tableView ly_hideEmptyView];
|
||||
```
|
||||
|
||||
|
||||
|
||||
### <a id="普通view调用示例"></a>8.普通view调用示例
|
||||
因普通view(包括scrollView)没有DataSource，代码层面无法判断view上有无数据，所以view想要实现占位图，
|
||||
还需通过两个方法来手动控制emptyView的显示和隐藏。
|
||||
以下是调用示例
|
||||
```Objective-C
|
||||
//1.先设置样式
|
||||
self.view.ly_emptyView = [MyDIYEmpty diyNoDataEmpty];
|
||||
//2.显示emptyView
|
||||
[self.view ly_showEmptyView];
|
||||
//3.隐藏emptyView
|
||||
[self.view ly_hideEmptyView];
|
||||
```
|
||||
### <a id="占位图完全覆盖父视图"></a>9.占位图完全覆盖父视图
|
||||
每个项目需求不同，有的占位图内容多大，占位图就多大，这种情况是默认的，不用设置属性。而有的占位图想要和父视图一样大，以达到覆盖住父视图的目的，这种情况下将LYEmptyView的emptyViewIsCompleteCoverSuperView属性值设置为YES即可。
|
||||
```Objective-C
|
||||
DemoEmptyView *emptyView = [DemoEmptyView diyEmptyView];
|
||||
emptyView.emptyViewIsCompleteCoverSuperView = YES;//完全覆盖父视图，背景色默认为浅白色，可自行设置
|
||||
//emptyView.backgroundColor = [UIColor redColor];//自己设置背景色为红色，此设置也可封装到公共的地方（DemoEmptyView），就不用每次都单独设置了
|
||||
self.tableView.ly_emptyView = emptyView;
|
||||
```
|
||||
|
||||
## 更新记录
|
||||
|
||||
### 2019-08-16 (pod V1.3.0)
|
||||
* 1.detailLab添加行间距属性
|
||||
* 2.每个子控件可单独设置间距
|
||||
* 3.actionBtn添加渐变背景颜色属性
|
||||
* 4.更改添加emptyView时其显隐的逻辑
|
||||
|
||||
### 2019-07-04 (pod V1.2.5)
|
||||
* 1.新增属性:按钮宽度actionBtnWidth
|
||||
* 2.修改属性默认值:按钮的圆角actionBtnCornerRadius默认改为0
|
||||
|
||||
### 2019-06-18 (pod V1.2.4)
|
||||
* 1.将点击重试事件加到emptyView上（当设置empty完全覆盖父视图时，就可实现点击屏幕重试的效果）
|
||||
* 2.swift项目中imageNamed:方法string为nil时崩溃解决
|
||||
|
||||
### 2018-12-04 (pod V1.2.3)
