ios - Unity Facebook SDK 7.0.2 在 iOS 中编译失败

Question

我目前使用的是 Unity 5.0.2 和 Unity FB SDK 7.0.2 Beta，在 iOS 编译期间出现问题。

错误是:

      RegisterMonoModules() in RegisterMonoModules.o

      RegisterMonoModules() in RegisterMonoModules.o

如果我使用 IL2CPP 编译，它会显示类似的错误以及一些额外的信息

有人知道怎么解决吗？

如果您发现 Xcode 项目中缺少 fbUnityInterface.h，请尝试以下操作:

在您的 Unity 项目中找到该文件，然后在检查器的“为插件选择平台”框中单击 iOS 复选框。

如果没有此复选框，Unity 可能不知道 .h 文件需要包含在构建中，因为它仅在 .mm 文件中引用，而 Unity 不会解析该文件。
