本文介绍如何在iOS应用中使用UIGestureRecognizer实现单击和双击手势的识别。通过设置不同类型的UIGestureRecognizer，可以区分并响应单次点击和连续两次点击的手势，同时确保了当系统检测不到双击手势时会再次尝试识别单击手势。

UITapGestureRecognizer *atap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(atapAction)];
    [self.view addGestureRecognizer:atap];
    
    UITapGestureRecognizer *doubleClick = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleClickAction)];
    doubleClick.numberOfTapsRequired = 2;
    [self.view addGestureRecognizer:doubleClick];
    
    //当系统检测不到双击手势时执行再识别单击手势
    [atap requireGestureRecognizerToFail:doubleClick];
