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 version:

let fnt = UIFont(name:"Helvetica", size:20.0)
let attributedString = NSMutableAttributedString(string:"GGG®GGG", attributes:[NSFontAttributeName : fnt!])
attributedString.setAttributes([NSFontAttributeName : fnt!.fontWithSize(10), NSBaselineOffsetAttributeName: 10], range: NSRange(location: 3, length: 1))
