How to change letter spacing in Swift?

Question

I'd like to change the letter spacing in the title of my navigation bar but I've had no success so far.

Thanks in advance.

Answer 1

A cool extension for UILabel:

extension UILabel{
func setCharacterSpacing(_ spacing: CGFloat){
    let attributedStr = NSMutableAttributedString(string: self.text ?? "")
    attributedStr.addAttribute(NSAttributedString.Key.kern, value: spacing, range: NSMakeRange(0, attributedStr.length))
    self.attributedText = attributedStr
 }
}

Usage:

label.setCharacterSpacing(4)

Answer 2

You can set the title via code passing the title string with some blank spacing ("E x a m p l e"), or with a tab (\t) or via code like this:

 let attributedString = NSMutableAttributedString(string: "Example")
 attributedString.addAttribute(NSKernAttributeName, value:   CGFloat(1.4), range: NSRange(location: 0, length: 9))

Then you assign attributedString to your title.

Answer 3

the bellow function works for me, hope this helps you too

func setCharacterSpacig(string:String) -> NSMutableAttributedString {

    let attributedStr = NSMutableAttributedString(string: string)
    attributedStr.addAttribute(NSKernAttributeName, value: 1.25, range: NSMakeRange(0, attributedStr.length))
    return attributedStr
}
