[英]Stripe on iOS: NSInvalidArgumentException for createTokenWithPayment
First ever post here!. 第一次在这里发布!
I have been trying to resolve this issue for several days - I created a super basic Stripe Payment example in Swift to learn mobile Payments. 几天来,我一直在尝试解决此问题-我在Swift中创建了一个超级基本的Stripe Payment示例,以学习移动支付。 This code should communicate with the basic python server I set up on the same machine/LAN. 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。
The problem is, as soon as I press the pay button, the Apple Pay view comes up, but pressing pay from there (on the simulator) then results in a crash with the following log output: 问题是,一旦按下付款按钮,就会出现Apple Pay视图,但是从那里(在模拟器上)按下付款会导致崩溃,并显示以下日志:
-[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'
Can't seem to find a solution in Stripe's or Swift's documentation for this. 在Stripe或Swift的文档中似乎找不到解决方案。 FWIW, this is based on the Ray Wenderlich Apple Pay example. FWIW,这是基于Ray Wenderlich Apple Pay的示例。 [link] Code is below, help would be very appreciated! [link]代码在下面,非常感谢您的帮助!
Update: adding the -ObjC linker flag removes the above errors. 更新:添加-ObjC链接器标志可消除上述错误。 There is however another error I can't figure out: Apple Pay screen now gives a 'Payment not completed' sign when I press Pay. 但是,还有一个我无法弄清的错误:当我按“付款”时,Apple Pay屏幕现在显示“付款未完成”标志。 Added a screenshot for reference. 添加了屏幕截图以供参考。

How are you integrating the Stripe SDK? 您如何集成Stripe SDK? One theory here is that if you're importing it as a static library, you need to make sure that you're building it with the -ObjC
flag - for more instructions here, see https://stripe.com/docs/mobile/ios#manual-installation . 这里的一种理论是,如果要将其作为静态库导入,则需要确保使用-ObjC
标志进行构建-有关此处的更多说明,请参见https://stripe.com/docs/mobile / ios#manual-installation 。
