title: How to place a currency symbol prefix or postfix with a string?
body: <p>I'm wondering if there is any official way to put a currency symbol to the left or to the right from the money amount, depending of the region and the currency itself?
  For example, if it's a $ sign, it should be to the left of the amount, as $20. If it's, for instance, € sign, then it should go as 20€.
  I've found a simple way, I just check with If statement if the currency symbol is $ and append it to the left or to the right to my NSString. But this looks a bit lame like a crutch method.
  I was unable to find some more convenient way. Is there any?
  Thank you.</p>
