iOS开发-UIImageView响应点击事件

UIImageView是不能够响应点击事件的，在开发过程中我们需要经常对头像等添加点击事件，上网搜索一番后发现有如下两个方法：

1.找到点击图片Event，添加事件处理函数

1 2 3 4 5 6 7 8 9 10 11 12 13 14

UIImageView.userInteractionEnabled = YES ; - ( void )touchesBegan:( NSSet *)touches withEvent:(UIEvent *)event {            UITouch *touch = [[event allTouches] anyObject];            if ([touch view] != UIImageView)      {          //do some method.....                }       }

 

2.为UIImageView添加Tap手势

1 2 3 4 5 6 7 8 9

UIImageView.userInteractionEnabled = YES ; UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector (handleSingleTap:)]; [UIImageView addGestureRecognizer:singleTap]; - ( void )handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {            //do something.... }

 

3.在UIImageView外层套一个UIView，在外层UIView上添加点击事件处理函数

1 2 3 4 5 6 7

UIView*view = [[UIControl alloc] initWithFrame:CGRectMake(50,200,150,150)] ; view.backgroundColor = [UIColor clearColor]; [(UIControl *)view addTarget: self action: @selector (xxx) forControlEvents:UIControlEventTouchUpInside]; UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@ "a.gif" ]]; imageView.frame = CGRectMake(0, 0, view.bounds.size.width, view.bounds.size.height); [view addSubview:imageView]; [ self .view addSubview:view];
