NSAttributedString superscript styling

Question

I want to superscript all the instances of ® character in a block of text (legal disclaimer, naturally ;)) and the default way NSAttributedString is not very go

Answer 1

Swift 4.2

In my example I want to subscript one instance of infinity symbol so my label's title will look like this:

let font = UIFont(name: "Helvetica", size: 14.0)

let attributedString = NSMutableAttributedString(string: "Solids(ΔE∞)•G7®", attributes: [NSAttributedStringKey.font : font!])

attributedString.setAttributes([NSAttributedStringKey.baselineOffset: -5], range: NSRange(location: 9, length: 1))

solidsLbl.attributedText = attributedString
