ios - iAd 涵盖了我对第一次加载的看法

Question

我使用 UITabBarController-iAds 的修改版本让 iAds 几乎完美地工作.我遇到的唯一问题是在第一次加载广告时我的观点就被覆盖了。一旦广告在 30 秒后刷新， View 就会调整大小。

我正在使用以下代码:

- (void)layoutBanner 
{ 
    float height = 0.0; 
    ADBannerView *_banner = (ADBannerView *)[self.view viewWithTag:12]; 
    CGRect bounds = [UIScreen mainScreen].bounds; 

    if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) { 
        _banner.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait; 
    } else { 
        _banner.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape; 
    } 

    //When compiling against iOS 8 SDK this needs to be height, regardless of the actual device orientation 
    height = bounds.size.height; 

    CGSize bannerSize = [ADBannerView sizeFromBannerContentSizeIdentifier:_banner.currentContentSizeIdentifier]; 

    //Get content view 
    UIView *_contentView = self.selectedViewController.view; 

    CGRect contentFrame = _contentView.frame; 
    CGRect bannerFrame = _banner.frame; 

    if (_banner.isBannerLoaded) { 
        if (iOS7) { 
            contentFrame.size.height = height - bannerSize.height; 
            bannerFrame.origin.y = contentFrame.size.height - self.tabBar.frame.size.height; 
        } else { 
            contentFrame.size.height = height - self.tabBar.frame.size.height - bannerSize.height; 
            bannerFrame.origin.y = contentFrame.size.height; 
        } 
    } else { 
        if (iOS7) { 
            contentFrame.size.height = height; 
            bannerFrame.origin.y = bounds.size.height; 
        } else { 
            contentFrame.size.height = height - self.tabBar.frame.size.height; 
            bannerFrame.origin.y = bounds.size.height; 
        } 
    } 

    [UIView animateWithDuration:0.25 animations:^{ 
        _banner.frame = bannerFrame; 
        _contentView.frame = contentFrame; 
    } completion:^(BOOL finished) { 
        [self.view bringSubviewToFront:_banner]; 
    }]; 
}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner 
{ 
    NSLog(@"Did load"); 
    [self layoutBanner]; 
} 

有什么想法吗？

我通过尝试动画 block 设法解决了这个问题。我移动了内容 View 行，它解决了问题

 [UIView animateWithDuration:0.25 animations:^{
 _banner.frame = bannerFrame;
 } completion:^(BOOL finished) {
     _contentView.frame = contentFrame;
     [self.view bringSubviewToFront:_banner];
 }];
