//单击事件 -(void)fun1 { NSLog(@"click1"); } //双击事件 -(void)fun2 { NSLog(@"click2"); } //单击和双击方法之一 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if ([[touches anyObject] tapCount] == 1) { [self performSelector:@selector(fun1) withObject:nil afterDelay:1]; } else if ([[touches anyObject] tapCount] ==2) { [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(fun1) object:nil]; [self performSelector:@selector(fun2) withObject:nil afterDelay:1]; } }

原理:执行第二个方法的时候,取消第一次的方法操作
- (void)viewDidLoad { [super viewDidLoad]; //点击事件 UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun1)]; //单点触摸 tap.numberOfTouchesRequired = 1; //点击几次,如果是1就是单击 tap.numberOfTapsRequired = 1; [self.view addGestureRecognizer:tap]; UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun2)]; tap2.numberOfTapsRequired = 2; [self.view addGestureRecognizer:tap2]; //如果满足第二次 第一次的就取消 [tap requireGestureRecognizerToFail:tap2]; }
