iOS 7 - UITextView size font to fit all text into view (no scroll)

Question

I am trying to find a non-deprecated method to size the font of a textview down so that all text fits in the textview without requiring scrolling.

The method \'sizeWithF

Answer 1

Swift 5+

    var fontSize = Font.Size.section.rawValue
    let minSize = Font.Size.large.rawValue

    while fontSize > minSize {
        let textViewSize = CGSize(width: textView.frame.size.width, height: textView.frame.size.height)
        let size = textView.sizeThatFits(textViewSize)

        if size.height <= textViewSize.height {
            break
        }

        fontSize -= 1.0
    }

    textView.font = Font.primary.of(size: fontSize)
