Unity Facebook SDK 7.0.2無法在iOS中編譯

Question

我目前正在使用Unity 5.0.2和Unity FB SDK 7.0.2 Beta在iOS編譯期間出現問題。

錯誤是：

Undefined symbols for architecture armv7:

      RegisterMonoModules() in RegisterMonoModules.o

      RegisterMonoModules() in RegisterMonoModules.o

如果我使用IL2CPP進行編譯，它將顯示類似的錯誤和一些額外的信息

任何人都知道如何解決它？

Answer 1

如果您發現Xcode項目中缺少fbUnityInterface.h ，請嘗試以下操作：

在Unity項目中找到該文件，然后在檢查器的“選擇插件平台”框中單擊iOS中的復選框。

如果沒有此復選框，Unity可能不知道.h文件需要包含在構建中，因為它僅在.mm文件中引用，Unity不會解析。

Answer 2

問題是XCode項目缺少Facebook綁定文件。

請確保Xcode中存在以下文件。

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