How to Convert Price to Global Currency Format in iOS

See NSNumberFormatter.

It can handle all your numeric formatting needs and do so in an automatically localized fashion, when used correctly (since currencies around the world are often written with different punctuation & formatting).

In particular, check out the number formatting guide linked to at the top of the class documentation.

Using NSNumberFormatter:

NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat: 1000.99]];
NSLog(@"%@", numberAsString);
