NSNumberFormatter class has built-in functionality for conversion numbers to words:

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle: NSNumberFormatterSpellOutStyle];
[formatter setLocale:...]; // Set locale if you want to use something other then the current one
NSString* numberString = [formatter stringFromNumber:[NSNumber numberWithInt: 100]];
