Hi I am trying to get autoGrowing textview height dynamically, i.e  I mean text data is coming from services for each time when we loading the app. 
And my main requirement is I want to find textview exact height because of sometimes textview data is increasing sometimes decreasing according to data which comes from services.
That's what I want to find and I don't want to resize textview because I have already that technique.
CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;
