Answer 1

I wouldn't say this is an "answer" per say, but since no one has responded yet (and I am unable to comment since I have <50 reputation points), I'll just throw this thought out there. Since GADBannerView is a subclass of UIView, just think of it as a regular view. You must be adding this view to the pushed view controller somehow without knowing it, otherwise it wouldn't be able to display the ad.
