title: UINavigationItem Prompt Animation Issue
body: <p>I have two <code>UITableViewController</code>s that are connected via a <code>Show</code> segue. The <code>prompt</code> property of <code>UINavigationItem</code> is set on both view controllers in Interface Builder. When the first view controller is shown, the prompt and navigation bar are both displayed properly, however, when performing a segue to the second view controller, the <code>title</code> and the back button animate undesirably. I have tried setting the prompts programmatically in the <code>viewWillLayoutSubviews</code>, <code>viewDidLayoutSubviews</code>, <code>viewDidLoad</code>, <code>viewWillAppear:</code>, and the <code>viewDidAppear:</code> methods of both view controllers, but I get the same effect. </p>
  
  <p>Any ideas on how to resolve this issue? I don't want to resort to a custom view for the <code>titleView</code> because I prefer the stock functionality, but I am not able to figure out how to fix the undesirable animation. </p>
