title: UIView not autoresizing correctly iPhone 3.5 inch vs 4 inch screen
body: <p>I have a UINavigationController that has as its top UIViewController a UIViewController with a UITabBar on it.  (It is not a UITabBarController b/c I am told that Apple does not want you to push a UITabBarController on a UINavigationController).  </p>
  
  <p>The UITabBar controls 3 UIViewControllers.  When I run it in the simulator, the 3 UIViewControllers work for the 3.5 inch screen, or the 4 inch screen depending on how I use the simulated metrics in Interface Builder.  But I can not get the autoresizing to work on both the 3.5 and 4 inch screen.  It seems like it's either or.</p>
  
  <p>This should be very simple since it's just UIAutosizeRemaskFlexibileWidth and Height.  I have tried this in code and also by playing with Interface builder, and the 3 UIViewControllers controlled by the UITabBar never fit the screen size.  I should not have to write branching code for different iphone screen sizes should I? </p>
