我一直在寻找如何嵌套 UIScrollViews。似乎它应该像使用容器滚动视图的 addSubview: 添加内部滚动视图一样简单。我的一切都在视觉上正确显示，但内部滚动视图的功能不存在，尽管为它们提供了适当的框架和内容大小。我下面的代码显示了我到目前为止所拥有的。只有外部滚动视图滚动。我想要它，以便外部滚动视图控制从左到右滚动，每个内部滚动视图控制其相关页面内容的垂直滚动。
self.containerScroll = [[UIScrollView alloc]init];
self.containerScroll.frame = CGRectMake(0,(self.headerView.frame.size.height + self.pageControl.frame.size.height),screenWidth, (screenHeight - (self.headerView.frame.size.height + self.pageControl.frame.size.height)));
self.containerScroll.backgroundColor = [UIColor clearColor];
self.containerScroll.alpha = 1;
self.containerScroll.pagingEnabled = YES;
self.containerScroll.contentSize = CGSizeMake(self.containerScroll.bounds.size.width*3,1);
self.containerScroll.bounces = NO;
self.containerScroll.delegate = self;
[self.view addSubview:self.containerScroll];
self.page1Scroll = [[UIScrollView alloc]init];
self.page1Scroll.frame = CGRectMake(0,0,self.containerScroll.bounds.size.width,self.containerScroll.bounds.size.height);
self.page1Scroll.backgroundColor = [UIColor redColor];
self.page1Scroll.alpha = 1;
[self.page1Scroll addSubview:self.feedPageVC.view];
self.page1Scroll.contentSize = CGSizeMake(320,500);
self.page1Scroll.delegate = self;
[self.containerScroll addSubview:self.page1Scroll];
self.page2Scroll = [[UIScrollView alloc]init];
self.page2Scroll.frame = CGRectMake(self.containerScroll.bounds.size.width,0,self.containerScroll.bounds.size.width,self.containerScroll.bounds.size.height);
self.page2Scroll.backgroundColor = [UIColor greenColor];
self.page2Scroll.delegate = self;
[self.containerScroll addSubview:self.page2Scroll];
self.page3Scroll = [[UIScrollView alloc]init];
self.page3Scroll.frame = CGRectMake(self.containerScroll.bounds.size.width*2,0,self.containerScroll.bounds.size.width,self.containerScroll.bounds.size.height);
self.page3Scroll.backgroundColor = [UIColor blueColor];
[self.page3Scroll addSubview:self.detailsPageVC.view];
self.page3Scroll.contentSize = CGSizeMake(320,500);
self.page3Scroll.delegate = self;
[self.containerScroll addSubview:self.page3Scroll];
