通过添加手势给UIImageView添加点击事件

//创建imageview

UIImageView  *headImage = [[UIImageView alloc]initWithFrame: CGRectMake(30, 43, 60, 60)];

headImage.image = [UIImage imageNamed:@"bg_me_title"];

[self.view  addSubview:headImage];

//打开用户交互

headImage.userInteractionEnabled = YES;

//给图片添加点击手势（也可以添加其他手势）

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(selectHeaderImage)];

       [headImage addGestureRecognizer:tap];

//点击事件
-(void)selectHeaderImage
{
//具体的实现
}
