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

swift 2.0 version:

    let _currencyFormatter : NSNumberFormatter = NSNumberFormatter()
    _currencyFormatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle
    _currencyFormatter.currencyCode = "EUR"
    textField.text = _currencyFormatter.stringFromNumber(amount);
