Answer 1

I'm having the same exception in one of my applications. Have you been able to figure this out?

Answer 2

Might be easier to answer with your header file, but did you set the interface to implement the delegate interface? You need to do that in your UIViewController in order to capture the iAd messages. And don't forget to #import .

If you set things up with Interface Builder -- and AFAICT you didn't and just create the iAd on the fly -- then there are other issues with setting your iAd delegate to your view which you do by connecting the iAd delegate to the "File's Owner" socket.

Anyway, check your header file and I hope this helps you both.
