我有一个应用程序以Apple提供的“iAd Suite”推荐的方式实现iAds，但是当我在iOS 4.3.3上使用iPhone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
{
}
我间歇性地收到了这个错误。

有没有人见过这种奇怪的东西？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
