title: presentViewController and displaying navigation bar
body: <p>I have a view controller hierarchy and the top-most controller is displayed as a modal and would like to know how to display the navigation bar when using </p>
  
  <pre><code>'UIViewController:presentViewController:viewControllerToPresent:animated:completion'
  </code></pre>
  
  <p>The docs for 'presentViewController:animated:completion:' note: </p>
  
  <blockquote>
    <p>'On iPhone and iPod touch, the presented view is always full screen.
    On iPad, the presentation depends on the value in the
    modalPresentationStyle property.'</p>
  </blockquote>
  
  <p>For 'modalPresentationStyle', the docs say:</p>
  
  <blockquote>
    <p>The presentation style determines how a modally presented view controller is displayed onscreen. On iPhone and iPod touch, modal view controllers are always presented full-screen, but on iPad there are several different presentation options. </p>
  </blockquote>
  
  <p>Is there way to ensure that the navigation bar is visible below the status bar once the view control displays itself? Should I interpret the doc as, you don't get any options of iPhone/iPod and only on iPad?</p>
  
  <p>Previously, I was using <code>'UIViewController:presentModalViewController:animated'</code> which worked fine, but since iOS 5.0, the API has been deprecated so I'm switching over to the new one.</p>
  
  <p>Visually, what I'm looking to do is have the new controller slide in from the bottom of the screen, just like the old API used to do.</p>
  
  <p>[updating with code]:</p>
  
  <pre><code>// My root level view:
  UIViewController *vc = [[RootViewController alloc] 
                              initWithNibName:nil 
                              bundle:[NSBundle mainBundle]];
  navController = [[UINavigationController alloc] initWithRootViewController:vc];        
  ....
  
  // Within the RootViewController, Second view controller is created and added 
  // to the hierarchy. It is this view controller that is responsible for 
  // displaying the DetailView:
  SecondTierViewController *t2controller = [[SecondTierViewController alloc] 
                                             initWithNibName:nil
                                             bundle:[NSBundle mainBundle]];
  
  [self.navigationController pushViewController:t2controller animated:YES];
  
  // Created by SecondTierViewController 
  DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil                                                                                 
                                          bundle:[NSBundle mainBundle]];  
  
  controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
  controller.modalPresentationStyle = UIModalPresentationCurrentContext;
  
  [self.navigationController presentViewController:controller 
                                          animated:YES
