contentSize of UITextView doesn't change when push UIViewController in landscape

I have UIViewController's view with UITableView. Custom UITableViewCell consists of two halfs: 1.question(UILabel) and 2.answer(UITextView).

Yes, I know that UITextView is very 'heavy' control but I want to recognize phone numbers and automatically return back to app after phone call ends.

1-st question: are there any other solution(without using UITextView) to achieve such behavior? Solution: custom UILabel + "tel://" 开发者_C百科url - don't work, it doesn't come back me to the app.

On top of this I want display disclose indicator when answer is longer than 2 lines. Since UITextView doesn't have property which tells haw many lines text has, I am calculating the count of text lines: textView.contentSize.height / textView.font.lineHeight;

2-nd question: When contentSize of UITextView is updated? I faced with problem, when push UIViewController in landscape mode, contentSize has default(Portrait) values.
