任何人都可以提供一点帮助吗？我刚刚收到来自 Apple 的反馈，建议我的应用程序无法被接受，因为它包含在没有提供广告时仍然可见的广告横幅，问题是我不知道该怎么做才能防止这个问题。

我们已完成对您申请的审核；但是，我们无法将此版本发布到 App Store，因为当广告内容不可用时，它会显示一个空的 iAd 横幅。当 iAd 不提供广告内容时，应隐藏应用程序中的横幅。我们在下面提供了其他详细信息，以帮助解释该问题。我们希望您考虑修改并重新提交您的申请。
要处理广告内容不可用的情况，您需要实现横幅视图委托。为方便起见，此处包含示例代码片段。此外，您可能希望查看 iAd 编程指南的“使用横幅视图”部分以了解具体细节： https ://developer.apple.com/iphone/prerelease/library/documentation/UserExperience/Conceptual/iAd_Guide/WorkingwithBannerViews/ WorkingwithBannerViews.html
横幅视图委托在广告不可用时删除横幅视图：
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
if (self.bannerIsVisible)
{
[UIView beginAnimations:@"animateAdBannerOff" context:NULL];
// assumes the banner view is at the top of the screen.
banner.frame = CGRectOffset(banner.frame, 0, -50);
[UIView commitAnimations];
self.bannerIsVisible = NO;
}
}
现在我正在努力解决的是如何处理该代码，当我尝试将其放入其中时只会抛出几个红色错误，所以我来寻求建议，任何人都可以在这里帮助我吗？
