Objective-C: How to format string as $ Price

Question

Is their a built-in way of formatting string as $ price, e.g. 12345.45 converted to $12,345.45?

Answer 1

Assuming the price is held in a float, you probably want +localizedStringWithFormat:.

NSString *priceString = [NSString localizedStringWithFormat:@"$ %'.2f",price];

Hmmm... Apple says they follow the IEEE standard for printf, so it should accept the ' flag, but it doesn't work on Tiger. NSNumberFormatter it is.
