Body
Apple isn't cutting down on it. This is the only way to create custom container view controllers prior to iOS 5. Apple actually listened to the developers and made it easier to do this sort of thing in iOS 5 with child and parent view controller methods, not to mention they made it so it worked hierarchically. In most cases, this wouldn't actually be a problem in terms of applications crashing or performance or anything. It can be a problem in some cases, because let's say you have a child view controller. You add the view controller's view to your root view controller. Prior to iOS 5, child view controllers were things like navigation controller view controllers, tab bar controller view controllers, and modal view controllers. What happens when you have a button that calls <code>[self.parentViewController dismissModalViewControllerAnimated:YES];</code>? Technically, the view controller isn't being presented as a modal view controller, you added the view to the root view controller view. In iOS5, you're able to add child view controllers to view controllers and are able to transition from one child view controller to another. Now even if your view controller doesn't have a different parent, adding a "root" view controller to another root view controller isn't the best way to do it (especially since you don't get access to the parent view controller unless you explicitly create a parentViewController pointer in the child view controller). So in the end, Apple just made it easier and more decoupled.

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.
