iAd width in landscape on iPad is narrow

I have an iAd in an iPad app. When the user rotates, I use setFrame to tell the ad's view to resize and move to the bottom of the screen. Unfortunately, although I am setting the width to 1024, iOS is not complying and the iAd's switch is rema开发者_高级运维ining at 768.

How to fix this?

Thanks.

To resize the banner view you must use the currentContentSizeIdentifier property. The documentation:

Your application should never directly change the size of the banner view. Instead, set the currentContentSizeIdentifier property to a known advertising size. The view is automatically resized to match the new content size.

So to resize the banner view for landscape, you would do the following:

bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;

If you need to know the actual size this will change the banner view's frame to, use the ADBannerView class method sizeFromBannerContentSizeIdentifier:. So if you resize the banner view for landscape, then the new size will be

CGSize bannerViewSize = [ADBannerView sizeFromBannerContentSizeIdentifier:ADBannerContentSizeIdentifierLandscape];
