 1 | # TanTan
 2 | 探探 和 陌陌 都有  
 3 | # 前提
 4 | 现在比较流行的社交软件都有这么一个功能模块，喜欢←划，不喜欢→划, 多么经典的一个广告语啊。   
 5 | 我就在业余时间写了这么一个demo样例
 6 | ![WechatIMG1.jpeg](http://upload-images.jianshu.io/upload_images/2368708-4e36e014ffd22e6b.jpeg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

 8 | 
 9 | 这两个都是比较参数经典的案例
10 | # 参数
11 | ```objc
12 | //代理
13 | @property (nonatomic, weak) id<TanTanDelegate>delegate;
14 | //数据源
15 | @property (nonatomic, weak) id<TanTanDataSource>dataSource;
16 | //是否设置循环
17 | @property (nonatomic, assign) BOOL isCyclically;
18 | //展示出来的item数目
19 | @property (nonatomic, assign) NSInteger showItemsNumber;
20 | //设置偏移量
21 | @property (nonatomic, assign) CGSize offSet;
22 | //显示的第一个View
23 | @property (nonatomic, strong , readonly) UIView *topView;
24 | //刷新展示数据
25 | - (void)refreshData;
26 | ```
27 | 我们可以通过设置isCyclically来实现视图是否循环，通过offset来设置重叠视图的重叠方向 `
28 | ```objc
29 | @protocol TanTanDataSource <NSObject>
30 | @required
31 | - (NSInteger)numberOfItemInTanTan:(TanTanView *)tantan;
32 | 
33 | - (UIView *)tantan:(TanTanView *)tantan
34 | viewForItemAtIndex:(NSInteger)index
35 |        reusingView:(UIView *)view;
36 | @end
37 | ```
38 | 上面的这个是数据源，这两个方法的思路和UITableView的数据源差不多，一个是设置数据源数目，一个就是视图复用
39 | ```objc
40 | @protocol TanTanDelegate <NSObject>
41 | @optional
42 | - (void)tantan:(TanTanView *)tantan beforeSwipingItemAtIndex:(NSInteger)index;
43 | - (void)tantan:(TanTanView *)tantan didRemovedItemAtIndex:(NSInteger)index;
44 | - (void)tantan:(TanTanView *)tantan didLeftRemovedItemAtIndex:(NSInteger)index;
45 | - (void)tantan:(TanTanView *)tantan didRightRemovedItemAtIndex:(NSInteger)index;
46 | ```
47 | 这就是相应的代理方法

50 | # 更新
51 | 当页面快速滑动的时候视图会出现BUG，已修复
