UIImageView是不能夠響應(yīng)點(diǎn)擊事件的，在開(kāi)發(fā)過(guò)程中我們需要經(jīng)常對(duì)頭像等添加點(diǎn)擊事件，上網(wǎng)搜索一番后發(fā)現(xiàn)有如下兩個(gè)方法：
1.找到點(diǎn)擊圖片Event，添加事件處理函數(shù)

UIImageView.userInteractionEnabled = YES;
- (void)touchesBegan:(NSSet*)touches withEvent:(UIEvent *)event{

    UITouch *touch = [[event allTouches] anyObject];
    if ([touch view] != UIImageView){

        //do some method.....

    }
}

2.為UIImageView添加Tap手勢(shì)

UIImageView.userInteractionEnabled = YES;
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[UIImageView addGestureRecognizer:singleTap];

- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer{
     //do something....

}
