For Arabic/English

NSString *regEx = @"^([a-zA-Z0-9\u0600-\u06ff](\\-|\\_|\\.|\\ )?)+$";
        NSPredicate *regExPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regEx];
        BOOL myStringMatchesRegEx = [regExPredicate evaluateWithObject: self.text];
        if (!myStringMatchesRegEx)
            return NO;
