插页式 iAd 实施

Question

我在使用 iAd 全屏广告时遇到问题。 我像这样实施 iAd：

 -(void)showFullScreenAd {
     //Check if already requesting ad
     if (requestingAd == NO) {
         [ADInterstitialAd release];
          interstitial = [[ADInterstitialAd alloc] init];
          interstitial.delegate = self;
          self.interstitialPresentationPolicy = ADInterstitialPresentationPolicyManual;
         [self requestInterstitialAdPresentation];
         NSLog(@"interstitialAdREQUEST");
         requestingAd = YES;
     }//end if
 }

 -(void)interstitialAd:(ADInterstitialAd *)interstitialAd didFailWithError:(NSError *)error {
     interstitial = nil;
     [interstitialAd release];
     [ADInterstitialAd release];
     requestingAd = NO;
     NSLog(@"interstitialAd didFailWithERROR");
     NSLog(@"%@", error);
 }

  -(void)interstitialAdDidLoad:(ADInterstitialAd *)interstitialAd {
     NSLog(@"interstitialAdDidLOAD");
     if (interstitialAd != nil && interstitial != nil && requestingAd == YES)      {
         [interstitial presentFromViewController:self];
         NSLog(@"interstitialAdDidPRESENT");
     }//end if
 }

 -(void)interstitialAdDidUnload:(ADInterstitialAd *)interstitialAd {
     interstitial = nil;
     [interstitialAd release];
     [ADInterstitialAd release];
     requestingAd = NO;
     NSLog(@"interstitialAdDidUNLOAD");
 }

 -(void)interstitialAdActionDidFinish:(ADInterstitialAd *)interstitialAd {
     interstitial = nil;
[interstitialAd release];
 [ADInterstitialAd release];
  requestingAd = NO;
  NSLog(@"interstitialAdDidFINISH");
  }

我正在调用“showFullScreenAd”来展示广告。但是在调用它 10 次后，我收到了这条消息，即使我关闭了这个 View Controller 并设置 interstitial = nill，：

警告：当前存在超过 10 个 ADBannerView 或 ADInterstitialView 实例。这是对 iAd API 的滥用，广告效果将因此受到影响。此消息仅打印一次。

我猜问题在于消除插页式广告。因为声明 interstitial = [[ADInterstitialAd alloc] init];

每次都会制作新的插页式广告实例。

我看到了一些关于此的主题，但没有回答如何正确关闭这些实例。

你需要调用viewDidLoad中的方法。

-(void)viewDidLoad 
{ 
  [self showFullScreenAd];
}

我在调用viewWillLayoutSubviews中的方法时遇到了这个问题。
