iAd 警告 - 横幅视图被遮挡

Question

我正在尝试在我现有的应用程序之一中实施 iAd。它有效，但我不断收到错误消息：ADBannerView：警告横幅视图有广告，但可能被遮挡。此消息仅在每个横幅视图中打印一次。

广告是否被遮挡或可能被遮挡？代码有问题吗？我想不通。我承认自己是个新手。任何帮助将不胜感激。谢谢你甚至看我的问题。

- (void)createBannerView {

        Class cls = NSClassFromString(@"ADBannerView");

    if (cls) {

        ADBannerView *adView = [[[cls alloc] initWithFrame:CGRectZero]autorelease];       

        adView.currentContentSizeIdentifier =ADBannerContentSizeIdentifierPortrait;

       adView.autoresizingMask =  UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin |UIViewAutoresizingFlexibleBottomMargin| UIViewAutoresizingFlexibleRightMargin |UIViewAutoresizingFlexibleLeftMargin;

        adView.delegate = self;

        CGRect bannerFrame =adView.frame;

        bannerFrame.origin.y = self.view.frame.size.height;
            adView.frame = bannerFrame;

             adView.frame = CGRectOffset(adView.frame, 0, -50);


        self.bannerView = adView;

        [self.view addSubview:adView];


    }

}

- (void)showBanner {

    CGFloat fullViewHeight = self.view.frame.size.height;

    CGRect tableFrame = self.tView.frame;

    CGRect bannerFrame = self.bannerView.frame;

    tableFrame.size.height = fullViewHeight - bannerFrame.size.height;

    bannerFrame.origin.y = fullViewHeight - bannerFrame.size.height; 

    [UIView beginAnimations:@"showBanner" context:NULL];

    self.tView.frame = tableFrame;

    self.bannerView.frame = bannerFrame;

    [UIView commitAnimations];

}

Answer 1

可能的是，当iad正在显示时，您在前面打开了一个modalView控制器或其他视图。这可能会导致模糊错误。

消除错误的最简单方法是删除 ViewWillDisappear 中的横幅视图：

-(void)viewWillDisappear:(BOOL)animated
{
    [bannerView removeFromSuperview];
}

Answer 2

尝试添加 [self.view BringSubviewToFront:bannerView];
