How to calculate TextView height base on text

Question

I am using the code below for calculate the height of text, then set this height for UILabel and UITextView

CGSize targetSize = CGS         


        

Answer 1

This calculates the size of any string, whether or not you put them in a text view.

let frame = NSString(string: yourText).boundingRect(
    with: CGSize(width: yourDesiredWidth, height: .infinity),
    options: [.usesFontLeading, .usesLineFragmentOrigin],
    attributes: [.font : yourFont],
    context: nil)

let height = frame.size.height
