    <p>I've been searching around on how to nest UIScrollViews. It seems like it should be as easy as adding the inner scroll views by using addSubview: of the container scroll view. I have everything showing up visually correct but the functionality of the inner scroll views is non existent despite supplying them with proper frames and content sizes. My code below shows what I have so far. Only the outer scroll view scrolls. I want it so that the outer scroll view controls left to right scrolling and each inner scroll view controls vertical scrolling of their related page content.</p> <pre><code>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]; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
