Is there a simple way to format currency into string in iOS?

Question

I need a way to format the price from NSNumber into a string like this: \"USD 0.99\", not \"$ 0.99\".

My game uses custom fonts, and they could not have the symbols

Nice example I found here http://bendodson.com/weblog/2014/12/10/skproduct-localized-price-in-swift/

import StoreKit

extension SKProduct {

    @objc func localizedPrice() -> String {
        let formatter = NSNumberFormatter()
        formatter.numberStyle = .CurrencyStyle
        formatter.locale = self.priceLocale
        return formatter.stringFromNumber(self.price)!
    }
}
