How to align text inside textView vertically?

Question

I want to align vertically the text inside my UITextView (so it will be in the middle of it). How can i achieve that? I looked up and could not find any answer that could h

Answer 1

Link your textview to your viewcontroller and name it as you want (let's say textView).

In viewDidLayoutSubviews function put this line:

textView.centerVertically()

Then under the last curly bracket of your class put this extension:

  extension UITextView {

    func centerVertically() {
        let fittingSize = CGSize(width: bounds.width, height: CGFloat.greatestFiniteMagnitude)
        let size = sizeThatFits(fittingSize)
        let topOffset = (bounds.size.height - size.height * zoomScale) / 2
        let positiveTopOffset = max(1, topOffset)
        contentOffset.y = -positiveTopOffset
    }

}

To use this function for swift2 just change CGFloat.greatestFiniteMagnitude to CGFloat.max
