29 | 30 | ## 一、效果展示 31 | 32 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/ImitateOtherApp.png) 33 | 34 | ## 二、集成方式 35 | 36 | 1.Cocoapods方式集成: `pod 'LYEmptyView'`
37 | 使用时导入头文件 `#import ` 38 |

39 | 2.手动下载集成: 将LYEmptyView文件夹，导入你的工程
40 | 使用时导入头文件：`#import "LYEmptyViewHeader.h"` 41 | 42 | 43 | ## 三、使用参考示例 44 | 45 | ### 1.一行代码集成空内容视图 46 | 47 | ```Objective-C 48 | //框架方法 49 | self.tableView.ly_emptyView = [LYEmptyView emptyViewWithImageStr:@"noData" 50 | titleStr:@"暂无数据，点击重新加载" 51 | detailStr:@""]; 52 | ``` 53 | 54 | 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） 55 | ```Objective-C 56 | //二次封装方法，调用简洁 57 | self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty]; 58 | ``` 59 | 60 | 完全低耦合，在你的项目中加入这一行代码就可集成
61 | 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 62 | 63 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example1.gif) 64 | 65 | ### 2.自由选择空内容元素 66 | ```Objective-C 67 | 交互事件可选择SEL或block方式 68 | self.tableView.ly_emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData" 69 | titleStr:@"无数据" 70 | detailStr:@"请稍后再试!" 71 | btnTitleStr:@"重新加载" 72 | target:target 73 | action:action]; 74 | self.tableView.ly_emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData" 75 | titleStr:@"" 76 | detailStr:@"" 77 | btnTitleStr:@"" 78 | btnClickBlock:^{}]; 79 | // imageStr   : 占位图片 80 | // titleStr   : 标题 81 | // detailStr   : 详细描述 82 | // btnTitleStr : 按钮标题 83 | ``` 84 | 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） 85 | 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 86 | 87 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example2.png) 88 | 89 | ### 3.自定义空内容元素 90 | 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
91 | 通过方法` + (instancetype)emptyViewWithCustomView:(UIView *)customView;`
92 | 传入一个View 即可创建一个自定义的emptyView 93 | ```Objective-C 94 | self.tableView.ly_emptyView = [LYEmptyView emptyViewWithCustomView:customView]; 95 | ``` 96 | 97 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example3.png) 98 | 99 | 100 | ### 4.自定义元素的UI样式 101 | 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 ^_^ 102 | ```Objective-C 103 | //初始化一个emptyView 104 | LYEmptyView *emptyView = [LYEmptyView emptyActionViewWithImageStr:@"noData" 105 | titleStr:@"无数据" 106 | detailStr:@"请稍后再试!" 107 | btnTitleStr:@"重新加载" 108 | btnClickBlock:^{}]; 109 | //元素竖直方向的间距 110 | emptyView.subViewMargin = 20.f; 111 | //标题颜色 112 | emptyView.titleLabTextColor = MainColor(90, 180, 160); 113 | //描述字体 114 | emptyView.detailLabFont = [UIFont systemFontOfSize:17]; 115 | //按钮背景色 116 | emptyView.actionBtnBackGroundColor = MainColor(90, 180, 160); 117 | 118 | //设置空内容占位图 119 | self.tableView.ly_emptyView = emptyView; 120 | ``` 121 | >这里只列举了一些常用的属性，更多属性请到LYEmptyView.h查看 122 | 123 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example4.png) 124 | ### 5.二次封装 125 | 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
126 | 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
127 | 128 | ##### 1)新建一个类继承自LYEmptyView，例如demo中的MyDIYEmpty 129 | ##### 2)重写`- (void)prepare` 方法，并修改想要改变的元素的UI样式 130 | ```Objective-C 131 | - (void)prepare{ 132 | [super prepare]; 133 | 134 | self.titleLabFont = [UIFont systemFontOfSize:25]; 135 | self.titleLabTextColor = MainColor(90, 180, 160); 136 | 137 | self.detailLabFont = [UIFont systemFontOfSize:17]; 138 | self.detailLabTextColor = MainColor(180, 120, 90); 139 | self.detailLabMaxLines = 5; 140 | 141 | self.actionBtnBackGroundColor = MainColor(90, 180, 160); 142 | self.actionBtnTitleColor = [UIColor whiteColor]; 143 | } 144 | ``` 145 | 操作上面的两步就可实现对样式的单独管理
146 | 调用方法不变，只是调用的类变成了MYDiyEmpty 147 | ```Objective-C 148 | self.tableView.ly_emptyView = [MyDIYEmpty emptyActionViewWithImageStr:@"noData" 149 | titleStr:@"无数据" 150 | detailStr:@"请稍后再试!" 151 | btnTitleStr:@"重新加载" 152 |                                                        btnClickBlock:^{}]; 153 | ``` 154 | ##### 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
155 | 在MyDIYEmpty.h定义方法`+ (instancetype)diyNoDataEmpty;`
156 | 在MyDIYEmpty.m实现方法 157 | ```Objective-C 158 | + (instancetype)diyNoDataEmpty{ 159 | return [MyDIYEmpty emptyViewWithImageStr:@"nodata" 160 | titleStr:@"暂无数据" 161 | detailStr:@"请检查您的网络连接是否正确!"]; 162 | } 163 | ``` 164 | >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
165 | self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty]; 166 | 167 | ### 6.延迟显示emptyView 168 | 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。 169 | 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 170 | ```Objective-C 171 | /** 172 | 一般用于开始请求网络时调用，ly_startLoading调用时会暂时隐藏emptyView 173 | 当调用ly_endLoading方法时，ly_endLoading方法内部会根据当前的tableView/collectionView的 174 | DataSource来自动判断是否显示emptyView 175 | */ 176 | - (void)ly_startLoading; 177 | 178 | /** 179 | 在想要刷新emptyView状态时调用 180 | 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， 181 | 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。 182 | */ 183 | - (void)ly_endLoading; 184 | ``` 185 | 186 | *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 187 | 188 | 以下是调用示例（具体细节可参看demo中的demo2） 189 | ```Objective-C 190 | //1.先设置样式 191 | self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty]; 192 | //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） 193 | self.tableView.ly_emptyView.autoShowEmptyView = NO; 194 | //3.网络请求时调用 195 | [self.tableView ly_startLoading]; 196 | //4.刷新UI时调用（保证在刷新UI后调用） 197 | [self.tableView ly_endLoading]; 198 | ``` 199 | 200 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example6.gif) 201 | 202 | ### 7.特殊需求，手动控制emptyView的显示隐藏 203 | 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。
204 | 本框架提供另外的两个方法来解决这个问题。 205 | 206 | ```Objective-C 207 | /** 208 | 手动调用显示emptyView 209 | */ 210 | - (void)ly_showEmptyView; 211 | 212 | /** 213 | 手动调用隐藏emptyView 214 | */ 215 | - (void)ly_hideEmptyView; 216 | ``` 217 | 218 | *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 219 | 220 | 以下是调用示例（具体细节可参看demo中的demo4） 221 | ```Objective-C 222 | //1.先设置样式 223 | self.tableView.ly_emptyView = [MyDIYEmpty diyNoDataEmpty]; 224 | //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） 225 | self.tableView.ly_emptyView.autoShowEmptyView = NO; 226 | //3.显示emptyView 227 | [self.tableView ly_showEmptyView]; 228 | //4.隐藏emptyView 229 | [self.tableView ly_hideEmptyView]; 230 | ``` 231 | 232 | ![](https://github.com/dev-liyang/LYEmptyView/blob/master/images/example7.gif) 233 | 234 | ### 8.普通view调用示例 235 | 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， 236 | 还需通过两个方法来手动控制emptyView的显示和隐藏。 237 | 以下是调用示例 238 | ```Objective-C 239 | //1.先设置样式 240 | self.view.ly_emptyView = [MyDIYEmpty diyNoDataEmpty]; 241 | //2.显示emptyView 242 | [self.view ly_showEmptyView]; 243 | //3.隐藏emptyView 244 | [self.view ly_hideEmptyView]; 245 | ``` 246 | ### 9.占位图完全覆盖父视图 247 | 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。 248 | ```Objective-C 249 | DemoEmptyView *emptyView = [DemoEmptyView diyEmptyView]; 250 | emptyView.emptyViewIsCompleteCoverSuperView = YES;//完全覆盖父视图，背景色默认为浅白色，可自行设置 251 | //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 252 | self.tableView.ly_emptyView = emptyView; 253 | ``` 254 | 255 | ## 更新记录 256 | 257 | ### 2019-09-20 (pod V1.3.1) 258 | * 完善scrollView的contentInset 259 | * 解决reloadData调用顺序导致empty被隐藏问题 260 | 261 | ### 2019-08-16 (pod V1.3.0) 262 | * detailLab添加行间距属性 263 | * 每个子控件可单独设置间距 264 | * actionBtn添加渐变背景颜色属性 265 | * 更改添加emptyView时其显隐的逻辑 266 | 267 | ### 2019-07-04 (pod V1.2.5) 268 | * 新增属性:按钮宽度actionBtnWidth 269 | * 修改属性默认值:按钮的圆角actionBtnCornerRadius默认改为0 270 | 271 | ### 2019-06-18 (pod V1.2.4) 272 | * 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） 273 | * swift项目中imageNamed:方法string为nil时崩溃解决 274 | 275 | ### 2018-12-04 (pod V1.2.3) 276 | * fix bug：当子控件的文字被设置为空并再次设置为非空时, 子控件无法正常显示 277 | * 新增属性：ignoreContentInset，是否忽略scrollView的contentInset 278 | 279 | ### 2018-09-11 (pod V1.2.2) 280 | * 新增构造方法，具体请查看LYEmptyBaseView.h 281 | 282 | ### 2018-08-22 (pod V1.2.1) 283 | * 大神的建议，不要手动调用layoutSubviews。优化baseView里setter方法调用的重绘机制，使用setNeedsLayout更加优美 284 | 285 | ### 2018-07-31 (pod V1.2.0) 286 | * 新增属性：emptyViewIsCompleteCoverSuperView, 占位图是否完全覆盖父视图 287 | 288 | ### 2018-05-11 (pod V1.1.0) 289 | * 新增普通View可设置占位图，实现所有的View都能集成占位图 290 | 291 | ### 2018-03-26 (pod V1.0.3) 292 | * 添加reloadSections、reloadRows、reloadItems 等方法的监听 293 | * emptyBaseView setter 方法bug fix 294 | 295 | ### 2018-02-09 (pod V1.0.2) 296 | * 解决只是在导入本框架的情况下，导致UIScrollView上的内容不显示的bug 297 | 298 | 299 | ## 技术交流 300 | 本人QQ:610005400
