如何检测UITextView的自动更正状态？

Question

How can I tell whether UITextView is in autocorrecting state? That is, the incorrect or incomplete part is highlighted and the candidate is popped up.

Neither selectedRange nor markedTextRange is useful for this.

I suppose you could force the autocorrect to be applied and then check to see if there are any changes (a modified version of this answer: https://stackoverflow.com/a/13012198/953105 ), however that will destroy the autocorrect suggestion. I'm not sure of your use case, but that could work.
