本文介绍如何在iOS应用中实现单击和双击手势的识别，并通过具体的代码示例展示了如何为UIView添加手势检测方法，以及如何区分单击与双击事件。

1.给View添加手势

//view添加两个手势检测方法
    self.currentPlayerView.userInteractionEnabled = YES;
    UITapGestureRecognizer *singleTapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleSingleTap:)];
    singleTapGesture.numberOfTapsRequired =1;
    singleTapGesture.numberOfTouchesRequired  =1;
    [self.currentPlayerView addGestureRecognizer:singleTapGesture];
    
    UITapGestureRecognizer *doubleTapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleDoubleTap:)];
    doubleTapGesture.numberOfTapsRequired =2;
    doubleTapGesture.numberOfTouchesRequired =1;
    //只有当doubleTapGesture识别失败的时候(即识别出这不是双击操作)，singleTapGesture才能开始识别
    [singleTapGesture requireGestureRecognizerToFail:doubleTapGesture];
    [self.currentPlayerView addGestureRecognizer:doubleTapGesture];

2.两个手势事件分别区分单击了还是双击了

//两个手势分别响应的方法
-(void)handleSingleTap:(UIGestureRecognizer *)sender{
    NSLog(@"单击--------------");
}

-(void)handleDoubleTap:(UIGestureRecognizer *)sender{
    NSLog(@"双击-------------- ");
}
