}

Production Mode On/Off

     {

     }];

        // number of restore count
        int numberOfTransactions = payment.transactions.count;

        for (SKPaymentTransaction *transaction in payment.transactions)
        {
            NSString *purchased = transaction.payment.productIdentifier;
            if([purchased isEqualToString:@"com.myproductType.product"])
            {
                //enable the prodcut here
            }

      [IAPShare sharedHelper].iap = [[IAPHelper alloc] initWithProductIdentifiers:dataSet];
  }

[IAPShare sharedHelper].iap.production = NO;

                      NSDictionary* rec = [IAPShare toJSON:response];
