Remove extra paddings to fit to a precisely measured text

suggest change

UITextView has extra paddings by default. Sometimes it’s annoying especially if you want to measure some text without view instance and place them at some area precisely.

Do this to remove such paddings.

messageTextView.textContainerInset = UIEdgeInsetsZero
messageTextView.textContainer.lineFragmentPadding = 0

Now you can measure text size using NSAttributedString.boundingRectWithSize(...), and resize a UITextView just to fit it to the text.

let budget = getSomeCGSizeBudget()
let text = getSomeAttributedString()
let textSize = text.boundingRectWithSize(budget, options: [.UsesLineFragmentOrigin, .UsesFontLeading], context: nil).size
messageTextView.frame.size = textSize // Just fits.

Found a mistake? Have a question or improvement idea? Let me know.
