如何使用Cyber source SDK iOS添加数量?

//Card data
        let cardData = InAppSDKCardData.init()
        cardData.accountNumber = txtCardNumber.text
        cardData.expirationMonth = txtMonth.text
        cardData.expirationYear = txtYear.text
        cardData.cvNumber = txtCVV.text

        //Create Transaction object
        let transactionObj = InAppSDKTransactionObject.init()
        transactionObj.billTo = getBillToData()
        transactionObj.cardData = cardData

        //Get the Merchant data and credentials and assign.
        transactionObj.merchant = getMerchantData()

        //Set the End point / Environment. Test or Live
        InAppSDKSettings.sharedInstance()?.inAppSDKEnvironment = INAPPSDK_ENV_TEST

        //Enable log for debugging
        InAppSDKSettings.sharedInstance()?.enableLog = true

        //Obtain the gateway sharted instance.
        let gatWay = InAppSDKGateway.sharedInstance()

        result = (gatWay?.performPaymentDataEncryption(transactionObj, with: self))!

        if (result) {
            NSLog("InAppSDK: Request Accepted. Expect the response in the delegate method.");
        }
        else {
            NSLog("InAppSDK: Request NOT Accepted. Verify the input values if any one is invalid.");
        }
