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 short Int extension for the English language that also accounts for and displays negative integers correctly:

extension Int {
    func ordinal() -> String {
        let suffix: String!
        // treat negative numbers as positive for suffix
        let number = (self < 0 ? self * -1 : self)

        switch number % 10 {
        case 0:
            suffix = self != 0 ? "th" : ""
        case 1:
            suffix = "st"
        case 2:
            suffix = "nd"
        case 3:
            suffix = "rd"
        default:
            suffix = "th"
        }

        return String(self) + suffix
    }
}
