title: How can I add an AdBannerView to a UITabViewController?
body: <p>I have read through Apple's docs and referenced their infamous <code>iAdSuite</code> sample code. I have looked at many tutorials and stackoverflow posts and I still cannot arrive at the solution.</p>
  
  <p><strong>How can I prevent iAd from being unloaded</strong>, while being compliant with Apple's terms, while I am using a <em>tabviewcontroller</em>, and <em>storyboard</em>?</p>
  
  <p>I have a <code>tabBarController</code> that splits into <strong>3</strong> separate <code>UINavigationControllers</code> with respective <code>UIViewControllers</code>.</p>
  
  <p>Is there a way to add an <code>AdBannerView</code> to the <code>UITabBarController</code>? I have tried using a container view without success. What do I do?</p>
