Question

我正在尝试在imageView中使用单击识别器（也是一个scrollView子项）。在Interface Builder中，我只创建并引用了scrollView。滚动工作，但无法识别单击事件（没有记录任何内容）。这是代码：

- (void)loadView {
[super loadView];

UIImage *myImage = [UIImage imageNamed:@"img1.jpg"];
imageView = [[UIImageView alloc] initWithImage:myImage];

[myImage release];

// add gesture recognizers to the image view
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];

[imageView addGestureRecognizer:singleTap];

[singleTap release];

[imageScrollView setContentSize:CGSizeMake(imageView.frame.size.width, imageView.frame.size.height)];

[imageScrollView addSubview:imageView]; }

- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
// single tap handling
NSLog(@"sinlgeTap called"); }

我环顾了几个小时，尝试了很多东西。也许看别人可以帮助更多。感谢。

我为imageView启用了userInteraction，并为scrollView启用了canCancelContentTouches选项：

[imageScrollView setCanCancelContentTouches:YES];
[imageView setUserInteractionEnabled:YES];

现在有效。
