objective c - Setting UITextView frame to content size no longer works in Xcode 5

Question

The code snippet below worked to resize a UITextView frame to it's content height, before installing Xcode 5 but it doesn't work since the upgrade:

CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;

I've searched and haven't found the fix. Any thoughts?

There's new stuff for this on iOS 7.

To get the "fitted" size used by the text view after it's updated its text, call usedRectForTextContainer: on the textView's layoutManager property, passing the textView's textContainer property as an argument.

Word of warning about scrolling: Be advised, though, that changing the frame size of a text view after it has updated it's text can have unexpected visual bugs if scrolling is disabled on your text view. If this happens, set scrolling enabled before editing the text of the text view, then disabling it after it's updated (if you need scrolling to remain disabled).
