uiGestureRecognizer在uiScrollView内的视图中

是否有人设法让uigesturerecognizer使用ui滚动视图的子视图?我的回电好像从来没有接到过。

作为一个简单的例子,我希望有一个分页滚动视图,在第三页上用一个UITapGestureRecognizer监听一个tap。但是我不能让它工作。

我可以这样做:

self.scrollView = [[[UIScrollView alloc] initWithFrame:self.view.frame] autorelease];
self.scrollView.pagingEnabled = YES;
self.scrollView.contentSize = CGSizeMake(self.section1ScrollView.frame.size.width * 3, self.scrollView.frame.size.height); //3 pages

UIImageView *p0 = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"page0.png"]] autorelease];
[self.scrollView insertSubview:p0 atIndex:self.scrollView.subviews.count];

UIImageView *p1 = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"page1.png"]] autorelease];
//code to move it to the next page
[self.scrollView insertSubview:p1 atIndex:self.scrollView.subviews.count];

UIImageView *p2 = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"page2.png"]] autorelease];
//code to move it to the next page
[self.scrollView insertSubview:p2 atIndex:self.scrollView.subviews.count];

UITapGestureRecognizer *p2TapRegocnizer = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(p2Tapped:)] autorelease];
//p2TapRegocnizer.delegate = self;
[p2 addGestureRecognizer:p2TapRegocnizer];
