ios - 在 ionic 中构建 IOS 应用程序时出现架构 x86_64 错误的重复符号

我构建了一个 ionic 应用程序并从中构建了 IOS 应用程序。当我尝试构建 IOS 应用程序时，我在此应用程序中使用了 firebase 推送通知，不断收到此错误。我怎样才能摆脱这里提到的重复文件

duplicate symbols for architecture x86_64

Best Answer-推荐答案

架构 x86_64 的重复符号

这意味着您已经加载了两次相同的函数。由于从其他链接器标志中删除 -ObjC 后问题消失，这意味着此选项导致函数加载两次:

来自技术问答

This flag causes the linker to load every object file in the library that defines an Objective-C class or category. While this option will typically result in a larger executable (due to additional object code loaded into the application), it will allow the successful creation of effective Objective-C static libraries that contain categories on existing classes.
