NSNumberFormatter and 'th' 'st' 'nd' 'rd' (ordinal) number endings

Question

Is there a way to use NSNumberFormatter to get the \'th\' \'st\' \'nd\' \'rd\' number endings?

EDIT:

Looks like it does not exist. Here\'s what I\'m using.

Here's a Swift solution that cycles through the user's preferred languages until it finds one with known rules (which are pretty easy to add) for ordinal numbers:

    extension Int {
        var localizedOrdinal: String {

            func ordinalSuffix(int: Int) -> String {
                for language in NSLocale.preferredLanguages() as [String] {

                switch language {
                    case let l where l.hasPrefix("it"):
                        return "°"
                    case let l where l.hasPrefix("en"):
                        switch int {
                        case let x where x != 11 && x % 10 == 1:
                            return "st"
                        case let x where x != 12 && x % 10 == 2:
                            return "nd"
                        case let x where x != 13 && x % 10 == 3:
                            return "rd"
                        default:
                            return "th"
                        }
                    default:
                        break
                    }
                }

                return ""
            }

            return "\(self)" + ordinalSuffix(self)
        }
    }
