iOS - Resize UILabel to match content?

I have a UILabel with linecount of 0. I set the text for this UILabel in code. How can I make the UILable to resize itself until it displays the full content? I don't want to take any space unless开发者_如何转开发 the text is long enough to be displayed in multiple lines.

You may be looking for [label sizeToFit]; That will get your label to crop tight on the text you give it.
