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

Swift 5 w/ no extensions

inside viewDidLoad():

textView.textAlignment = .center

Answer 2

If you want to do this using the storyboard, you could add a view inside of your textView. Then, set the constraints that you used for the textView to the new view. Finally, add the following constraints to your text view:

• (right and left) O and point to the new view

• using the alignment constraints, add a vertically constraint.

Answer 3

This is used to center the text horizontal.

Answer 4

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

Answer 5

Swift 5

Put the following extension below your last curly bracket in your ViewController:

// MARK: - UITextView extension
extension UITextView {

    func centerVerticalText() {
        self.textAlignment = .center
        let fitSize = CGSize(width: bounds.width, height: CGFloat.greatestFiniteMagnitude)
        let size = sizeThatFits(fitSize)
        let calculate = (bounds.size.height - size.height * zoomScale) / 2
        let offset = max(1, calculate)
        contentOffset.y = -offset
    }
}

Call this function after you set the text.

yourTextView.centerVerticalText()

Answer 6

The above answer is correct, just want to add solution for those updating the textView on real time/onEditing.

Use the above extension and add the delegate method as well.

func textViewDidChange(_ textView: UITextView) { textView.centerVertically() }
