title: iPhone: Show modal UITableViewController with Navigation bar
body: <p>I am showing a modal view which is a <code>UITableViewController</code> class.  For some reason it won't show the navigation bar when I show it.  Here is my code:</p>
  
  <pre><code>SettingsCreateAccount *detailViewController = [[SettingsCreateAccount alloc] initWithStyle:UITableViewStyleGrouped];
      detailViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
      detailViewController.navigationController.navigationBarHidden = NO;
      [self.navigationController presentModalViewController:detailViewController animated:YES];
      detailViewController = nil;
      [detailViewController release];
  </code></pre>
  
  <p>I thought it was shown by default?  If it helps, I am calling this from another class that is also a <code>UITableViewController</code> managed by a <code>UINavigationController</code>.  Ideas?</p>
