title: Why doesn't my root view's height take account of its navigation bar?
body: <p>I was under the impression that a UINavigationController's navigation bar would always push down the child view's height, such that the child view's origin was at the bottom of the title bar.</p>
  
  <p>But when I present a view controller like this ...</p>
  
  <pre><code>MyViewController *viewController = [[MyViewController alloc] init];
  UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
  viewController.title = @"My View Controller";
  viewController.navigationItem.prompt = @"My Prompt";
  viewController.delegate = self;
  
  [self presentModalViewController:navigationController animated:YES];
  [navigationController release]; [viewController release];
  </code></pre>
  
  <p>... and then check <code>self.view.frame.size.height</code> with an NSLog in <code>viewDidLoad</code>, it reports that my view is 460px high. Shouldn't it subtracting the height of my title &amp; prompt? </p>
