UIView 快速添加手势事件（runtime）

直接贴代码
需要的朋友直接创建一个UIView 的分类 复制粘贴即可

#import <UIKit/UIKit.h>


@interface UIView (UserInteraction)

/**
 添加手势点击事件

 @param block 回掉
 */
- (void)addTapGestureActionWithBlock:(void (^)(UITapGestureRecognizer *tapAction))block;


/**
 添加手势长按事件

 @param block 回掉
 */
- (void)addLongPressGestureActionWithBlock:(void (^)(UILongPressGestureRecognizer *longPressAction))block;
