Re: Text layout responsibility

Try changing the container size once the layout is complete, you can do this by using the delegate method: - (void)layoutManager:(NSLayoutManager *)layoutManager didCompleteLayoutForTextContainer:(NSTextContainer *)textContainer atEnd:(BOOL)layoutFinishedFlag and checking the layoutFinishedF
