Failed to get call to iOS 7 iAd delegate methods

Question

If I create a new project of the same kind in Xcode 5.0.2, add the iAd Framework by implementing the ADInterstitialAdDelegate in ViewController.h

#import <UIKit/UIKit.h> #import <iAd/iAd.h> @interface ViewController : UIViewController <ADInterstitialAdDelegate> @end 

and delegate methods in ViewController.m

 -(void)viewDidLoad { [super viewDidLoad]; [ self performSelector:@selector(onDelay) withObject:nil afterDelay:2 ]; } -(void)onDelay { self.interstitialPresentationPolicy = ADInterstitialPresentationPolicyManual; [ self requestInterstitialAdPresentation ]; } -(void)interstitialAd:(ADInterstitialAd *)interstitialAd didFailWithError:(NSError *)error { NSLog(@"interstitialAd didFailWithError"); } -(void)interstitialAdDidLoad:(ADInterstitialAd *)interstitialAd { NSLog(@"interstitialAdDidLoad"); } 

none of the ADInterstitialAdDelegate methods are called . I am also experiencing some problems using the old implementation in iOS 6 and below.

 interstitial = [[ADInterstitialAd alloc] init]; interstitial.delegate = self; [ interstitial presentFromViewController:self ]; 

Only

 -(void)interstitialAdDidLoad:(ADInterstitialAd *)interstitialAd 

called then but no

 - (void)interstitialAdDidUnload:(ADInterstitialAd *)interstitialAd 

after closing the ad. Does anyone remember the same problems or know what is going on here?
