title: iAd Banner Question
body: <p>I am getting this warning when I switch views (which are just different themes) in my app.  Any ideas, suggestions on why the app is not loading?</p>
  
  <p>2011-04-25 16:14:20.211 MyApp [4121:40b] ADBannerView: WARNING A banner view (0x631bb30) has an ad but may be obscured. This message is only printed once per banner view.</p>

  <p>It appears that when the view switches, the other view is just in the background, any ideas on how to do this.</p>
  
  <p>** Note there is an excellent example on Apple's developer site, called iADSuite </p>
