Add protocol to my view controller
@interface adViewerViewController : UIViewController
This way I will have the definition as an ADBanner delegate. I first implemented a very simple set of callbacks to verify that I set my delegate in interface builder correctly.
//The Add banner delgate methods.
// This method is invoked each time a banner loads a new advertisement. Once a banner has loaded an ad,
// it will display that ad until another ad is available. The delegate might implement this method if
// it wished to defer placing the banner in a view hierarchy until the banner has content to display.
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
// This method will be invoked when an error has occurred attempting to get advertisement content.
// Possible error codes defined as constants in ADManager.h.
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
// Update the text display with informaito about the error.
// This message will be sent when the user taps on the banner and some action is to be taken.
// Actions either display full screen content in a modal session or take the user to a different
// application. The delegate may return NO to block the action from taking place, but this
// should be avoided if possible because most advertisements pay significantly more when
// the action takes place and, over the longer term, repeatedly blocking actions will
// decrease the ad inventory available to the application. Applications may wish to pause video,
// audio, or other animated content while the advertisement's action executes.
- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave
// All we do is display ads, we have NO desire to block it.
// This message is sent when a modal action has completed and control is returned to the application.
// Games, media playback, and other activities that were paused in response to the beginning
// of the action should resume at this point.
- (void)bannerViewActionDidFinish:(ADBannerView *)banner
