UIImageView 添加点击事件

clickx 作为一个方法被调用，表示当你点击图片的时候出发这个方法，这个方法可以自己随便写比如abc,clicky

- (IBAction)test:(id)sender {  UIImageView *imageView =[[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 200, 200)];  imageView.image=[UIImage imageNamed:@"22.png"];  imageView.userInteractionEnabled = YES;  [imageView setTag:2];//为了带个参数过去，设置值大一些  UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(clickx:)];  [imageView addGestureRecognizer:singleTap];  //[singleTap release];  [self.view addSubview:imageView]; }

UITapGestureRecognizer 带过来的参数 gesture 将索引值tag给传递过来

- (IBAction)clickx:(id)sender,UITapGestureRecognizer *gesture{ UIView *temView = [gesture view]; NSInteger temIndex = temView.tag; NSLog(@"aaaa%d",temIndex); }
