[IOS]实现IOS单击或者双击事件
提供一下三种方法参考：方法一：
- (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];}
