ios - 检测在 uiscrollView 中点击了哪个 UIImage

Question

我有一个 UIScrollView装载了几个 UIImages ，对于这个例子，它加载了 5 UIImages 中的相同图片.如何检测 UIImages 中的哪一个？用户点击的？

这就是我正在使用的:

    _thumbnailScroll.delegate = self;

    [_thumbnailScroll setBackgroundColor:[UIColor blueColor]];
    [_thumbnailScroll setCanCancelContentTouches:NO];

    _thumbnailScroll.indicatorStyle = UIScrollViewIndicatorStyleWhite;
    _thumbnailScroll.clipsToBounds = NO;
    _thumbnailScroll.scrollEnabled = YES;
    _thumbnailScroll.pagingEnabled = YES;

    NSUInteger nimages = 0;
    NSInteger tot=0;
    CGFloat cx = 0;
    for (nimages = 0; nimages < 5 ; nimages++) {

        UIImage *image = [UIImage imageWithContentsOfFile:[path stringByAppendingPathComponent:@"newPics/thumb/thumb1.png" ]];
        if (tot==5) {
            break;
        }
        if (5==nimages) {
            nimages=0;
        }

        UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

        CGRect rect = imageView.frame;
        rect.size.height = 150;
        rect.size.width = 150;
        rect.origin.x = cx;
        rect.origin.y = 0;

        imageView.frame = rect;


        [_thumbnailScroll addSubview:imageView];
        _thumbnailScroll.userInteractionEnabled = YES;
        // [imageView release];

        cx += imageView.frame.size.width+100;
        tot++;
    }

    //self.pageControl.numberOfPages = nimages;
    [_thumbnailScroll setContentSize:CGSizeMake(cx, [_thumbnailScroll bounds].size.height)];

有任何想法吗 ？

将此用于循环内的点击监听器。

 UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self    action:@selector(onSingleTapGestureRecognized:)];
 singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;
 singleTap.delegate = self;
 [imageview1 addGestureRecogniser:singleTap];
 [singleTap1 release];

  imageview1.userInteractionEnabled = YES;
