如何在图像的uiscrollview中捕捉事件

嗨,我已经用图片填充了uiscrollview(代码如下),但是我不知道如何在里面的图片中添加一些事件。我想双击滚动视图中的图像并获取一些事件。有什么方向可以实现吗?

arrayOfImages = [[NSMutableArray alloc] init];
    NSString *img;
    for (img in imgArray)
    {
        [arrayOfImages addObject:[UIImage imageNamed:img]];
    }

    NSLog(@"Array initialization complete...");

    scrollView = [[UIScrollView alloc] init];
    scrollView.scrollEnabled = YES;
    scrollView.pagingEnabled = YES;
    scrollView.directionalLockEnabled = YES;
    scrollView.showsVerticalScrollIndicator = NO;
    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.delegate = self;
    scrollView.backgroundColor = [UIColor blueColor];
    scrollView.autoresizesSubviews = YES;
    scrollView.frame = CGRectMake(0, 0, 320, 29);
    [self.view addSubview:scrollView];

    NSLog(@"Scroll View initialization setup complete...");

    UIImage *imageToAdd;
    int x = 0;
    int y = 0;
    for (imageToAdd in arrayOfImages)
    {
        UIImageView *temp = [[UIImageView alloc] initWithImage:imageToAdd];     

        temp.frame = CGRectMake(x, y, 29, 29);
        x += 29;
        [scrollView addSubview:temp];

    }

    NSLog(@"Adding images to outlet complete...");
