first you create the number formatter object with decimal style then convert your number to the formatted string

    NSNumberFormatter *formatter = [NSNumberFormatter new];
    [formatter setNumberStyle:NSNumberFormatterDecimalStyle];


    long priceInt =  10000000;


    NSString *formatted = [formatter stringFromNumber:[NSNumber numberWithLong:priceInt]];

@interface NSString (NumberPadTools)

- (NSString*)numberPadformattedString;

@end


@implementation NSString (NumberPadTools)

- (NSString*)numberPadformattedString {
    NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
    [formatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
    [formatter setNumberStyle:NSNumberFormatterDecimalStyle];
    formatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
    [formatter setGroupingSeparator:@","];
    [formatter setDecimalSeparator:@"."];
    [formatter setMaximumFractionDigits:12];
    // Decimal values read from any db are always written with no grouping separator and a comma for decimal.

    NSNumber *numberFromString = [formatter numberFromString:self];

    [formatter setGroupingSeparator:@","]; // Whatever you want here
    [formatter setDecimalSeparator:@"."]; // Whatever you want here

    NSString *finalValue = [formatter stringFromNumber:numberFromString];
    return finalValue;
}

@end
