iOS 4.3.3中出现奇怪的iAd错误

我有一个应用程序以Apple提供的“iAd Suite”中推荐的方式实现iAds，但是当我使用iOS 4.3.3在iPhone上运行应用程序时，我会遇到一些奇怪的行为

具体来说，虽然我实现了委托并实现了以下方法

#pragma mark ADBannerViewDelegate methods -(void)bannerViewDidLoadAd:(ADBannerView *)banner { //NSLog(@"LOADING AN AD"); [self layoutForCurrentOrientation:YES]; } -(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { [self layoutForCurrentOrientation:YES]; } -(BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave { return YES; } -(void)bannerViewActionDidFinish:(ADBannerView *)banner { } 

我间歇性地得到了这个错误。

有没有人见过这种怪异？ 我注意到的另一件事是我可以使用模拟器（不是版本的iPhone 4.0,4.1,4.2）使它失败..这只发生在我安装到我的实际设备或在4.3.3模拟器上运行时
