一、UIView自带有的触摸事件
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; if (touch.tapCount == 2) // 双击 NSLog(@"++++++++++++++++++++++++++++++++++++++++%lu", [touch tapCount]); if (event.allTouches.count == 2) // 两根手机触摸 NSLog(@"++++++++++++++++++++++++++++++++++++++++%lu", [event.allTouches count]); }
只需实现该事件函数即可。但是，注意，若是在UIViewController里有一个UITableView，点击该UITableView，触摸事件是会被UITableView截断的

二、手势UITapGestureRecognizer
UITapGestureRecognizer可以添加到任何的UIView控件上
// 默认是单指单机触发 UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard:)]; [self.view addGestureRecognizer:tap]; // tap.numberOfTapsRequired = 1; // 单击数 // tap.numberOfTouchesRequired = 1; // 手指数 ... - (void)dismissKeyboard:(UITapGestureRecognizer *)tap { // TODO }
