If I have a number int aNum = 2000000 how do I format this so that I can display it as the NSString 2,000,000?

Don’t do your own number formatting. You will almost certainly not get all the edge cases right or correctly handle all possible locales. Use the
NSNumberFormatterfor formatting numeric data to a localized string representation.You would use the
NSNumberFormatterinstance method-setGroupingSeparator:to set the grouping separator to@","(or better yet[[NSLocale currentLocale] objectForKey:NSLocaleGroupingSeparator]; thanks @ntesler) and-setGroupingSize:to put a grouping separator every 3 digits.
