Question

我正在使用此代码隐藏iAd，因为Apple文档建议。但有时候它并没有隐藏iAd，即使是日志记录也暗示了if-block运行的内部代码。

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    NSLog(@"Error loading");

    if (isAdVisible == YES )
    {
        NSLog(@"Inside error loading");
        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];
        banner.frame = CGRectMake(0, -50, 320, 50);
        [UIView commitAnimations];
        isAdVisible = NO;
    }
}

我使用CGRectOffset来偏移banner.frame（它返回一个原点偏离源矩形的矩形）。然后我用一个块启动动画。以下代码在bannerView:didFailToReceiveAdWithError:内调用，调整我UITabBarController.tabBar的大小并隐藏它下面的AdBannerView：

-(void) hideBanner: (UIView*) banner
{
    NSLog(@"Running %@ '%@'", self.class, NSStringFromSelector(_cmd));

    // Hide the banner by sliding down while resizing the contentController.view.frame
    if(banner && !banner.isHidden){

        CGRect tabBarFrame = self.contentController.tabBar.frame;

        [UIView animateWithDuration:0.25 animations:^{

            self.contentController.tabBar.frame = CGRectOffset(tabBarFrame, 0, banner.frame.size.height);
            banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);

        } completion:^(BOOL finished) {
            banner.hidden = YES;
        }];
    }
}

ios iAds没有正确隐藏
