PKPaymentAuthorizationViewController 总是 returns 无？

Question

我正在尝试为我的应用程序设置 Apple Pay，但出于某种原因，PKPaymentViewController 总是返回为 nil（如果代码中的语句是为了测试这个）？有什么想法吗？

@IBAction func payAction(_ sender: Any) {

    price = donationAmount.text
    print(price)

    let request = PKPaymentRequest()
    request.merchantIdentifier = applePayMerchantID
    request.supportedNetworks = SupportedPaymentNetworks
    request.merchantCapabilities = PKMerchantCapability.capability3DS
    request.countryCode = "GBR"
    request.currencyCode = "GBP"
    request.requiredBillingAddressFields = PKAddressField.all

    //request.applicationData = "This is a test".dataUsingEncoding(NSUTF8StringEncoding)

    let paymentSummary = [PKPaymentSummaryItem(label:"Sponsorship", amount: 10.00)]

    request.paymentSummaryItems = paymentSummary

    let applePayController: PKPaymentAuthorizationViewController = PKPaymentAuthorizationViewController(paymentRequest: request)

    applePayController.delegate = self;


    if(applePayController == nil){
        print("___")
    } else{
        self.present(applePayController, animated: true, completion: nil)
    }
}


func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {
    completion(PKPaymentAuthorizationStatus.success)
}

func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {
    controller.dismiss(animated: true, completion: nil)
}
