插页式 iAd 实现

Question

我遇到了iAd全屏广告的问题。我像这样实现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");
  }

我打电话给"showFullScreenAd"来展示广告。但是在调用它 10 次后，即使我关闭此视图控制器并设置插页式 = nill，我也会收到此消息：

警告：当前存在 10 多个 ADBannerView 或 ADInterstitialView 实例。这是对iAd API的滥用，广告性能将因此受到影响。此消息仅打印一次。

我想问题在于忽略插页式广告。因为声明 插页式广告 = [[ADInterstitialAd alloc] init];

每次都会产生新的插页式广告实例。

我看到的关于此的主题很少，但没有答案如何正确消除这些实例。

你需要在viewDidLoad中调用方法。

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

当我在 viewWillLayoutSubviews 中调用该方法时，我遇到了这个问题。
