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?

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.

It appears that when the view switches, the other view is just in the background, any ideas on how to do this.

\*\* Note there is an excellent example on Apple's developer site, called iADSuite
