How to overcome the 2,147,483,647 issue NSNumberFormatter

Question

-(NSString *)convertCurrency:(NSString *)textFieldString{
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];

    [numberFormatter setNumberStyle: NSNumberFormatterNoStyle];
    [numberFormatter setGroupingSize:3];
    [numberFormatter setGroupingSeparator:@","];
    [numberFormatter setUsesGroupingSeparator:YES];
    [numberFormatter setMaximumIntegerDigits:20];
    number= [NSNumber numberWithInt:[textFieldString intValue]];
    NSString *numberString = [NSString stringWithFormat:@"$%@",[numberFormatter stringForObjectValue:number]];
    return numberString;
}

When I send the textfield string value is send 10000000000 only return the $2,147,483,647 but I want only $10,000,000,000. how to solve this issue.

Answer 1

Use a long long. That's assuming $9,223,372,036,854,775,807 is enough.

NSNumber* number = [NSNumber numberWithLongLong:[textFieldString longLongValue]];
NSString* numberString = [numberFormatter stringFromNumber:number];

BTW you could have just used

[numberFormatter setCurrencySymbol:@"$"];

instead of -stringWithFormat: to add the dollar sign.
