[tapaddTarget:selfaction:@selector(tapIconView:)]; 3.手势识别的状态: typedef NS_ENUM (NSInteger,UIGestureRecognizerState){ / / 没有触摸事件发生,所有手势识别的默认状态 UIGestureRecognizerStatePossible, / / 一个手势已经开始但尚未改变或者完
[tap addTarget:self action:@selector(tapIconView:)];
3.手势识别的状态:
typedef NS_ENUM(NSInteger, UIGestureRecognizerState) {
// 没有触摸事件发生,所有手势识别的默认状态
UIGestureRecognizerStatePossible,
// 一个手势已经开始但尚未改变或者完成时
UIGestureRecognizerStateBegan,
// 手势状态改变
UIGestureRecognizerStateChanged,
// 手势完成
UIGestureRecognizerStateEnded,
// 手势取消,恢复至Possible状态
UIGestureRecognizerStateCancelled,
// 手势失败,恢复至Possible状态
UIGestureRecognizerStateFailed,
// 识别到手势识别
UIGestureRecognizerStateRecognized = UIGestureRecognizerStateEnded
