Question

tapGesture = [[UITapGestureRecognizer alloc] initWithTarget：self 动作：@selector（handleTapGesture :)]; tapGesture.numberOfTapsRequired = 2; tapGesture.numberOfTouchesRequired = 1;
[self.view addGestureRecognizer:tapGesture];
[tapGesture release];

和

- (void)handleTapGesture:(UITapGestureRecognizer *)sender {

     if (sender.state == UIGestureRecognizerStateRecognized) {
  // handling code
        NSLog(@"We got double tap here");
        DashBoardViewController*   dashboardObj = [[DashBoardViewController alloc] initWithNibName:@"DashBoardViewController" bundle:nil];
        [self.navigationController pushViewController:dashboardObj animated:YES];
 }

我想要做的是，我想在单击和双击时调用2个不同的事件。那么我怎样才能检测到tap == 1并点击== 2？双击在我的代码中被识别，但我不确定，如何找到并工作，只需点击一下。

这可能会给你一个解决方案

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];

[doubleTap setNumberOfTapsRequired:2];
[singleTap setNumberOfTouchesRequired:1];

[self.view addGestureRecognizer:singleTap];
[self.view addGestureRecognizer:doubleTap];

- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
// single tap action
}

- (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer {
   // double tap action
}

或者你必须使用NSTimer，因为darren指出要验证单次触摸。

在方法中，

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

关于iOS中的触摸似乎是一篇很好的帖子。
