Two UITapGestureRecognizer in on UIView

Question

我想添加到我的UIViewController：

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，则调用两个方法，我希望如果用户双击，则仅调用第一个（handleTapGesture），如果他点击一次，它将仅调用第二个（handleTapGesture2）

Answer 1

使用这个。

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];

你可以使用我在这里发布的代码在此requireGestureRecognizerToFail:使用的方法viewcontroller.m这将解决您的问题
