我目前正在为Capcitor应用开发一个原生插件。我对原生iOS开发、Swift和Obj-C几乎没有经验。
我使用了一个用C++编写的框架（FunSDK）。我在一个C2C ++ Package 器中调用它。如下所述：https://medium.com/@cecilia.humlelu/set-up-c-library-dependencies-in-swift-projects-5dc2ccd2ddaf
然后通过桥接头在Swift中使用 Package 器。到目前为止，这是可行的，我可以从框架中调用函数，并且它们可以正确执行。然而，框架的函数是异步执行的。当获得结果时，总是执行“OnFunSDKResult”方法。
在这个步骤中，我在调试时得到一个EXC_BAD_ACCESS错误。然后我在诊断设置下勾选了“Zombie objects”。这会导致执行停止并显示EXC_BREAKPOINT。
据我所知，在执行iniXMSDK方法之后，FunSDKWrapper类在执行“OnFunSDKResult”方法之前从内存中清除？
我也已经集成了一个completion函数，它只在“OnFunSDKResult”方法中调用，这样数据就被传输到Swift类中。然而，这也没有帮助。
我不知道该怎么办。希望有人能帮帮我。
如果你需要更多的信息，我很乐意提供。

提前感谢您提供的信息。
不幸的是，FunSDK的文档并不是很好。
这是一个演示应用程序，其中使用了框架的所有功能：https://gitlab.xmcloud.io/demo/FunSDKDemo_iOS
文档中并没有描述如何调用“OnFunSDKResult”方法。在DemoApp中的某个地方，只有这样的注解：“所有带有回调信息的FUN接口都会回调到这个方法中。”
EXC_BAD_ACCESS错误也只在我实现“OnFunSDKResult”方法时发生。所以我假设框架以某种方式通过“UI_SendMsg”将数据返回给“OnFunSDKResult”方法。
我现在基本上明白ARC释放了 Package 器。从关于内存管理的教程中，我仍然没有弄清楚如何在我的情况下改变这一点。
谁能给予我一个代码示例，说明我如何确保ARC只在某个时间释放 Package 器？我还读到我可以显式地为个别类禁用ARC，并自己接管内存管理。这是一个选项，以便我只在“OnFunSDKResult”中再次手动释放内存吗？

现在，我可以通过从FunSDKWrapper和CompletionManager创建一个强引用来解决这个问题。
