how to convert india number to arabic number?

i'm trying to make calls from my app, but it seems i can't because the numbers are in india format (example : ٩٦٦٥٩٥٨٤٨٨٨٢) and to make it work , I have to convert this string to arabic format (example : 966595848882)

my code : 

NSString *cleanedString = [[ContactInfo componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""];

NSString *phoneNumber = [@"telprompt://" stringByAppendingString:cleanedString];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

Use NSNumberFormatter with the appropriate locale. For example:

NSString *indianNumberString = @"٩٦٦٥٩٥٨٤٨٨٨٢";
NSNumberFormatter *nf1 = [[NSNumberFormatter alloc] init];
NSLocale *locale = [NSLocale localeWithLocaleIdentifier:@"hi_IN"];
[nf1 setLocale:locale];

NSNumber *newNum = [nf1 numberFromString:indianNumberString];
NSLog(@"new: %@", newNum);

This prints "966595848882".

I'm not 100% certain on the locale identifier above-- hi_IN should be "Hindi India". If that's not correct, use [NSLocale availableLocaleIdentifiers] to get a list of all known locale identifiers, and find one that's more appropriate.

Update: in order to pad this out to nine digits (or however many you want), convert back to an NSString using standard NSString formatting:

NSString *paddedString = [NSString stringWithFormat:@"%09ld", [newNum integerValue]];

The format %09ld will zero-pad out to nine digits.

It's also possible to do this using the same number formatter, converting the number above back into a string while requiring 9 digits. This also gives at least nine digits, with zero padding if necessary:

[nf1 setMinimumIntegerDigits:9];
NSString *reverseConvert = [nf1 stringFromNumber:newNum];
