Question

嗨我实现了这个功能，我可以手势，但我怎么能识别哪个手势是什么？例如简单地向左或向右移动？

我的处理代码：

/*this function is made to handel finger gesture and flip the view to other account*/
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{



    FirstViewController *screen = [[FirstViewController alloc] initWithNibName:nil bundle:nil];

    screen.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    screen.myArray = myArray;    
    [self presentModalViewController:screen animated:YES];
    [screen release];

}

感谢您的回答

嗯，这很大程度上取决于你想要陷阱的姿势。如果它是一个简单的捏，轻击水龙头等，那么你应该使用this document中描述的Apple新（3.2）便利类之一。

使用这些，捕获手势就像在代码中添加以下内容一样简单：

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

然后实现该方法以在找到它时处理该手势：

- (void)handleDoubleDoubleTap:(UIGestureRecognizer *)sender {
      //Do something here
}

这将陷入双击。
