Unity Facebook SDK 7.0.2在iOS中編譯失敗

Question

我目前在iOS編譯時使用Unity 5.0.2和Unity FB SDK 7.0.2 Beta時遇到問題。

的錯誤是：

clang: error: linker command failed with exit code 1 (use -v to see invocation) 

如果我使用IL2CPP編譯，它會顯示一些額外的信息

任何人都知道如何解決它類似的錯誤？

Answer 1

問題是XCode項目缺少Facebook綁定文件。

請確保以下文件存在於Xcode中。

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

Answer 2

如果發現fbUnityInterface.h從Xcode項目缺失，試試這個：

在您的Unity項目中找到該文件，並在檢查器中的「選擇插件平臺」框中點擊iOS複選框。

沒有這個複選框，Unity可能不知道.h文件需要包含在構建中，因爲它只在.mm文件中引用，而Unity不解析該文件。
