在iOS中的InApp购买付款

我需要使用InApp购买来订阅计划。进行付款，但我正在显示沙盒环境中的警报，例如“您想购买....”。我需要添加我的卡详细信息，并显示一些示例交易。如何重定向到付款并添加卡详细信息？如何在以下情况下完成InApp购买付款 实时环境。

// MARK: - IAP payment queue
    func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        for transaction:AnyObject in transactions {
            if let trans = transaction as? SKPaymentTransaction {
                switch trans.transactionState {
                case .purchased:
                    hideLoader()

                    if let paymentTransaction = transaction as? SKPaymentTransaction {
                        SKPaymentQueue.default().finishTransaction(paymentTransaction)
                    }

                    if productID == PRODUCT_ID {
                        UserDefaults.standard.set(true, forKey: "isPurchased")
                        lblPurchaseDone.text = "Pro version PURCHASED!"
                        lblPurchaseDone.isHidden = false
                        btnPurchase.isHidden = true
                        btnRestore.isHidden = true
                        self.present(Utilities().showAlertContrller(title: "Purchase Success", message: "You've successfully purchased"), animated: true, completion: nil)
                    }
                case .failed:
                    hideLoader()
                    if trans.error != nil {
                        self.present(Utilities().showAlertContrller(title: "Purchase failed!", message: trans.error!.localizedDescription), animated: true, completion: nil)
                        print(trans.error!)
                    }
                    SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
                case .restored:
                    print("restored")
                    SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
                default: break
                }
            }
        }
    }
