title: How to implement tab bar controller with navigation controller in right way
body: <p>I am using Storyboard and Xcode 6. I have next controllers and scenes in my Storyboard:</p>
  
  <p><code>UINavigationController</code> that has <code>HomeViewController</code> as a root. <code>HomeViewController</code> has a button that <code>Show (e.g. Push)</code> <code>UITabBarController</code>. <code>UITabBarController</code> has 4 <code>UIViewControllers</code>.</p>
  
  <p>But my problem that after I Show <code>UITabBarController</code> there are no Navigation Bars in 4 <code>UIViewControllers</code>. But I supposed that if I <code>Show (e.g. Push)</code> <code>UITabBarController</code> then it should has embedded navigation controller that is initial controller in storyboard. Am I right? And if so how can I setup then navigation bar in Storyboard, because there are now default bar event in pushed tab bar that I see on storyboard. I have selected UIViewController and set simulated metrics in identity inspector to Translucent Navigation bar for the Top property, but I supposed it should be automatically added to this controller and to the tab bar without additional steps.</p>
  
  <p>Or should I add new navigation controller for each tab bar items that will have their root view controllers?</p>
  
  <p>The main question why I don't see navigation bar in storyboard using show (e.g. Push). For example if I add navigation controller and then set as root - tab bar controller then Xcode automatically add top navigation bar, but if the queue has an extra step like in my case HomeViewController the top navigation bar never appear automatically.</p>
