Question

首先在这里发帖！。

我一直试图解决这个问题好几天 - 我在Swift中创建了一个超级基本Stripe Payment示例来学习移动支付。此代码应与我在同一台机器/ LAN上设置的基本python服务器通信。

问题是，只要按下付款按钮，Apple Pay视图就会出现，但是从那里按下付款（在模拟器上）然后会导致以下日志输出崩溃：

-[STPAPIClient createTokenWithPayment:completion:]: unrecognized selector sent to instance 0x7fe54a4f2d00  
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[STPAPIClient createTokenWithPayment:completion:]: unrecognized selector sent to instance 0x7fe54a4f2d00'

似乎无法在Stripe或Swift的文档中找到解决方案。 FWIW，这是基于Ray Wenderlich Apple Pay的例子。 [link]代码如下，非常感谢帮助！

更新：添加-ObjC链接器标志会删除上述错误。然而，我无法弄清楚的另一个错误：Apple Pay屏幕现在提供的付款未完成＆＃39;当我按下付款时签字。添加了screenshot以供参考。

        completion(STPBackendChargeResult.Failure, NSError(domain: StripeDomain, code: 50, userInfo: [NSLocalizedDescriptionKey: "Token value is \(token.tokenId)."]))

您如何整合Stripe SDK？这里的一个理论是，如果您将其作为静态库导入，则需要确保使用-ObjC标记构建它 - 有关此处的更多说明，请参阅https://stripe.com/docs/mobile/ios#manual-installation。
