在很多app中就有UITableViewCell左滑出现菜单如系统删除按钮，但是系统的只能有一个，有很多需求需要个性化不仅可以放文字还可以放按钮修改背景色创建多个菜单项，，那么系统提供的肯定不适合，所以我们需要自己手工打造。 直接上代码如下： WHC_MenuCell.h 头文件如下：
<NSObject>- (: ((((((nonatomic,assign) id<WHC_MenuCellDelegate>delegate;//cell代理//单击菜单项- (void)clickMenuItem:(UIButton*)sender;//关闭菜单- (BOOL)closeCellWithAnimation:(BOOL)b;//关闭批量菜单- (BOOL)closeCellWithTableView:(UITableView*)tableView index:(NSInteger)index animation:(BOOL)b;//开始或者正在拉开菜单- (void)startScrollviewCell:(BOOL)state x:(CGFloat)moveX;//结束拉开菜单- (void)didEndScrollViewCell:(BOOL)state;@end
WHC_MenuCell.m源文件如下：
