Uitransitionview and Uilayoutcontainerview

1. What's UITransitionView ?
2. What's UILayoutContainerView ?
3. Would I get in trouble for adding subviews to them?

They is the superviews of a UITableView which was inside of a UINavigationController which is inside of a UITabBarController .

UITransitionViewI got by asking for the superview of the table view. UILayoutContainerViewI got by asking for the superview of UITransitionView .

They is both internal views used by Apple and no published in the SDK.

It's difficult to say exactly what Apple would or won ' t do however, adding a view to an undocumented view you retrieve from A superview message is not contentious. What's the should not does (or be careful if your do does) is make assumptions about the view you are adding to. Specifically its class but even basic things like the fact that it even exists.

What is your trying to do? There may is a simpler way-like adding your view directly to the app ' s UIWindow.
