This is my first time implementing iAd, so it is probably a newb mistake. In my app delegate I initialize an iAd banner view and assign it to a delegate property, then in my View Controller I add it as a subview to the view, then add the main view to the view. When it displays, only the top strip (perhaps 20 pixels) of the iAd banner are shown above the main view. I thought adding subviews to the main view controller's view would automatically manage the position of the views. If I don't show the main view, I can see the full iAd banner.
I checked the view's resizing mask, but I don't know how to specify that the main view gets "squeezed" below the iAd banner view.
