Unity Facebook SDK 7.0.2在iOS上编译失败

Question

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

错误信息如下：

如果我使用IL2CPP编译，可能会出现类似错误的提示，其中还包含一些额外的信息。

有人知道怎样解决吗？

Answer 1

如果你发现Xcode项目中缺少fbUnityInterface.h文件，请尝试以下操作：

在Unity项目中找到该文件，并在检查器中的“选择插件平台”框中勾选iOS选项。

没有勾选此复选框，Unity可能不知道需要将.h文件包含在构建中，因为它仅在.mm文件中被引用，而Unity不解析该文件。

这个对我解决了问题！虽然，FBUnityUtility.h 对我来说也需要检查以使其编译。所以一个建议是在项目搜索窗口中输入“fbunity”，并检查结果列表中列出的所有文件，以确保 iOS 复选框被选中。 - user1029978

Answer 2

问题是XCode项目缺少Facebook绑定文件。

请确保以下文件存在于Xcode中。

1. fbUnityInterface.h和fbUnityInterface.m（FB绑定文件）
2. NativeDialogModes.cs
3. FacebookSDK

即使这些文件没有在Xcode中呈现，我也无能为力。 - Cadrick Loh

这些文件位于Unity文件夹中。请手动将它们添加到您的XCode项目中。 - Zohaib Javed
