I have View Controller with UITextView and in the bottom I have iAds.
When I access the View Controller I get an error: <Error>: CGAffineTransformInvert: singular matrix. Why?
Everything works fine, but when I change from Portrait to Landscape or vice-versa I get this error twice.
Maybe something is wrong with the UITextView and the iAds?
That's absolutely ok. Dont worry about this. That's Xcode trouble. iAd would working fine in production.
