NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber *myNumber = [NSNumber numberWithInteger:122344];
NSString *formattedNumberString = [numberFormatter stringFromNumber:myNumber];
[numberFormatter release];  // if you aren't using ARC.
NSLog(@"formattedNumberString: %@", formattedNumberString);
