objective-c - 如何让我的 iAd 横幅显示在屏幕底部？

Question

我有以下代码可以将它放在顶部。我希望它出现在底部。

 adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
 adView.frame = CGRectOffset(adView.frame, 0, -50);
 adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
 adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
 [self.view addSubview:adView];

我们将不胜感激。

更新——@larsacus 指出这是针对 4.2+ 的:

adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
CGRect adFrame = adView.frame;
adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
adView.frame = adFrame;
[self.view addSubview:adView];
