How to properly format currency on ios

Question

I\'m looking for a way to format a string into currency without using the TextField hack.

For example, i\'d like to have the number \"521242\" converted into \"5,212

Answer 1

func getCurrencyFormat(price:String)->String{
    let convertPrice = NSNumber(double: Double(price)!)
    let formatter = NSNumberFormatter()
    formatter.numberStyle = .CurrencyStyle
    formatter.currencyCode = "USD"        

    let convertedPrice = formatter.stringFromNumber(convertPrice)       
    return convertedPrice!
}

Note:- A currency code is a three-letter code that is, in most cases, composed of a country’s two-character Internet country code plus an extra character to denote the currency unit. For example, the currency code for the Australian dollar is “AUD”.
