一旦我 select 在 STPAddCardViewController() 上完成,应用程序就会加载并且不会停止加载

Once I select done on the STPAddCardViewController() the app loads and doesn't stop loading

我使用本教程将支付集成到我的应用程序中:

但是当我 select 在 STPAddCardViewController() 上完成时,应用程序加载并且不会停止加载。我将打印语句添加到教程中显示的扩展中,希望它能告诉我代码在哪里停止,但显示了 none 的打印语句。如下所示:

extension OrderDetialsViewController: STPAddCardViewControllerDelegate {

    func addCardViewControllerDidCancel(_ addCardViewController: STPAddCardViewController) {
        print("addCard")
        navigationController?.popViewController(animated: true)
    }

    private func addCardViewController(_ addCardViewController: STPAddCardViewController,
                             didCreateToken token: STPToken,
                             completion: @escaping STPErrorBlock) {
        print("addCard Created Token")
        var totalCost = 0
        for i in 0...localData.shoppingCart.itemSizeArray.count-1{
            if localData.shoppingCart.itemSizeArray[i] == "hd"{
                totalCost = totalCost+2000
            }
            else if localData.shoppingCart.itemSizeArray[i] == "d"{
                totalCost = totalCost+4000
            }
            else if localData.shoppingCart.itemSizeArray[i] == "free"{
                totalCost = totalCost + 0
            }
            else if localData.shoppingCart.itemSizeArray[i] == "home" {
                totalCost = totalCost + 500
            }
        }
        StripeClient.shared.completeCharge(with: token, amount: totalCost) { result in
            print("StripeClient")
          switch result {
          case .success:
            completion(nil)
            let alertController = UIAlertController(title: "Congrats on your order",
                                  message: "Your payment was successful! Check email for confirmation!",
                                  preferredStyle: .alert)
            let alertAction = UIAlertAction(title: "OK", style: .default, handler: { _ in
              self.navigationController?.popViewController(animated: true)
            })
            alertController.addAction(alertAction)
            self.present(alertController, animated: true)
            self.createOrderEmailBody()
            self.createCustomerOrderBody()
            self.changeUserRewardsScore()
          case .failure(let error):
            print(error)
            completion(error)
          }
        }
  }
}

您使用的是什么版本的 iOS SDK?

如果是v16.0.0之后的版本,需要实现didCreatePaymentMethod函数来取回一个PaymentMethod对象,didCreateToken方法已废弃

您还必须实施 PaymentIntents,因为 PaymentMethods 只能与 PaymentIntents 一起使用,这是推荐的集成。

这里有一个关于如何在您的 iOS 应用中开始使用 PaymentMethods 和 PaymentIntents 的教程:https://youtu.be/s5Ml41bZidw?t=57
