    <p>Following up on the previous answer, there are some times when you would like to load multiple views at the same time. Here's an example: You are displaying a report with multiple pages and you're going to use a UIScrollView to manage them. When the user is done browsing the report, he will close the report which will dismiss the view.</p> <p>Create a UIScrollView in a XIB along with a UIView for each page you need. Since the UIViews are part of the XIB, they will be loaded into memory together, all at once, when the report is opened. Create two UIViewControllers and use them to display the page being viewed and the one being scrolled to. As the user moves through the pages, re-use the UIViewController on the page being scrolled away from to hold the page being scrolled to.</p> <p>This will ensure great performance while the user is flipping through the pages. It loads all the pages at once up front into memory. I only uses two UIViewControllers, and it just changes which views are in them and moves them around.</p> <p>This also has the great benefit of having all of the pages in one XIB. It makes it easier to edit, and quicker to load than separate XIB's. You just have to make sure you have the memory to load all the pages at once. If it's static content (such as in my case) it's a great way to go.</p> <p>If you're looking for a good example of how to do this, I found this resource to be an excellent starting point:</p> <p><a href="http://cocoawithlove.com/2009/01/multiple-virtual-pages-in-uiscrollview.html" rel="nofollow noreferrer">http://cocoawithlove.com/2009/01/multiple-virtual-pages-in-uiscrollview.html</a></p>

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.
