NSString *text;
NSDecimalNumber *someNumber = [NSDecimalNumber decimalNumberWithString:number];
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];

Try this, I hope this helps you :
NSString *NumberString = #"۸۸۸";
NSNumberFormatter *Formatter = [[NSNumberFormatter alloc] init];
NSLocale *locale = [NSLocale localeWithLocaleIdentifier:#"EN"];
[Formatter setLocale:locale];
NSNumber *newNum = [Formatter numberFromString:NumberString];
if (newNum) {
NSLog(#"%#", newNum);
}
//print in console 888

You must take care of not only Persian numbers, but also Arabic ones.
Use the below functions/methods to do so:
// Convert string From English numbers to Persian numbers
+(NSString *) convertToPersianNumber:(NSString *) string {
NSNumberFormatter *formatter = [NSNumberFormatter new];
formatter.locale = [NSLocale localeWithLocaleIdentifier:#"fa"];
for (NSInteger i = 0; i < 10; i++) {
NSNumber *num = #(i);
string = [string stringByReplacingOccurrencesOfString:num.stringValue withString:[formatter stringFromNumber:num]];
}
return string;
}
// Convert string From Arabic/Persian numbers to English numbers
+(NSString *) convertToEnglishNumber:(NSString *) string {
NSNumberFormatter *formatter = [NSNumberFormatter new];
formatter.locale = [NSLocale localeWithLocaleIdentifier:#"fa"];
for (NSInteger i = 0; i < 10; i++) {
NSNumber *num = #(i);
string = [string stringByReplacingOccurrencesOfString:[formatter stringFromNumber:num] withString:num.stringValue];
}
formatter.locale = [NSLocale localeWithLocaleIdentifier:#"ar"];
for (NSInteger i = 0; i < 10; i++) {
NSNumber *num = #(i);
string = [string stringByReplacingOccurrencesOfString:[formatter stringFromNumber:num] withString:num.stringValue];
}
return string;
}

Follow the same. Just replace your locale identifier with "en".
