iphone - UIView中有两个UITapGestureRecognizer

我想添加到我的UIViewController中:

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture:)];
tapGesture.numberOfTapsRequired = 2;
[self.view addGestureRecognizer:tapGesture];
[tapGesture release];

UITapGestureRecognizer *tapGesture2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture2:)];
tapGesture2.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tapGesture2];
[tapGesture2 release];

问题是如果用户点击两次则调用了两种方法，而我希望如果用户双击只有一次(handleTapGesture)将被调用，并且如果他进行一次点击它将仅调用第二种方法(handleTapGesture2)

最佳答案

用这个..

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture)];
tapGesture.numberOfTapsRequired = 2;
[self.view addGestureRecognizer:tapGesture];
[tapGesture release];

UITapGestureRecognizer *tapGesture2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture2)];
tapGesture2.numberOfTapsRequired = 1;

[tapGesture2 requireGestureRecognizerToFail: tapGesture];

[self.view addGestureRecognizer:tapGesture2];
[tapGesture2 release];
