- (void)viewDidLoad

{

UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];

imageView.userInteractionEnabled = YES;

UITapGestureRecognizer *singleTap =

[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(whenClickImage)];

[imageView addGestureRecognizer:singleTap];

[imageView setImage:[UIImage imageNamed:@"1.png"]];

[singleTap release];

[self.view addSubview: imageView];

}

-(void)whenClickImage

{

NSLog(@"you click image");

}

不仅UIImageView可以添加，UIScrollView上也可以。还可以添加其他双击旋转等手势。

比较简单实用。
