Deleting obj and bin files.删除 obj 和 bin 文件。

Clean & Rebuild the solution.清理并重建解决方案。

For the error MT5209 I have changed the architecture, and I hope it will work in real devices.对于错误MT5209，我已经更改了架构，希望它能在真实设备上运行。 These are the errors I am getting.这些是我得到的错误。

2 个解决方案

This happens when the native linker cannot find an Objective-C class.当本机 linker 找不到 Objective-C class 时，就会发生这种情况。 You can add the [Protocol] attribute to the api that binds the Objective-C protocol for annotation, this official document can help you solve the problem.可以在绑定Objective-C协议的api中添加[Protocol]属性进行注解，这个官方文档可以帮你解决问题。

I solved this by simply changing the supported architectures to just x86_64 from iOS properties.我通过简单地将支持的架构从 iOS 属性更改为 x86_64 来解决这个问题。 Double click iOS project to open iOS properties window and set like below.双击iOS项目打开iOS属性window如下设置。 Clean and rebuild;清理和重建； error will be gone.错误将消失。
