    <p>Let me describe the situation I am trying to do:</p> <p>I have a list of Items. When I go into ItemDetailView, which is a UITableView. I want to do paging here like: When I scroll down out of the table view, I want to display the next item. Like in Good Reader:</p> <p><a href="http://img245.yfrog.com/img245/2073/pricethat.jpg" rel="nofollow noreferrer">Paging examples http://img245.yfrog.com/img245/2073/pricethat.jpg</a> Currently, I am trying 2 approaches but both do not really work for me. 1st: I let my UITableView over my scroll view and I have a nice animation and works quite ok except sometimes, the UITableView will receive event instead of my scroll view. And because, a UITableView is already a UITableView, this approach seems not be a good idea. Here is some code:</p> <pre><code>- (void)applicationDidFinishLaunching:(UIApplication *)application { // a page is the width of the scroll view scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * kNumberOfPages); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = YES; scrollView.scrollsToTop = NO; scrollView.delegate = self; [self loadScrollViewWithPage:0]; } - (void)loadScrollViewWithPage:(int)page { if (page &lt; 0) return; if (page &gt;= kNumberOfPages) return; [self.currentViewController.view removeFromSuperview]; self.currentViewController = [[[MyNewTableView alloc]initWithPageNumber:page] autorelease]; if (nil == currentViewController.view.superview) { CGRect frame = scrollView.frame; [scrollView addSubview:currentViewController.view]; } } - (void)scrollViewDidScroll:(UIScrollView *)sender { if (pageControlUsed) { return; } CGFloat pageHeight = scrollView.frame.size.height; int page = floor((scrollView.contentOffset.y - pageHeight / 2) / pageHeight) + 1; [self loadScrollViewWithPage:page]; } - (IBAction)changePage:(id)sender { int page = pageControl.currentPage; [self loadScrollViewWithPage:page]; // update the scroll view to the appropriate page CGRect frame = scrollView.frame; [scrollView scrollRectToVisible:frame animated:YES]; pageControlUsed = YES; } </code></pre> <p>My second approach is: using pop and push of navigationController to pop the current ItemDetail and push a new one on top of it. But this approach will not give me a nice animation of scrolling down like the first approach.</p> <p>So, the answer to how I can get it done with either approach will be appreciated</p>

Guidance
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.
