unity Firebase iOS 构建未定义符号：_OBJC_CLASS_$_FIRApp

Question

我正在尝试按照官方文档将 Firebase 集成到我的 iOS 平台的 Unity 项目中。 但是，当我尝试从 XCode 编译 Unity 构建时，我面临以下问题：

 Undefined symbols for architecture arm64: "_OBJC_CLASS_$_FIRDatabaseReference", referenced from: objc-class-ref in libFirebaseCppDatabase.a(database_reference_ios.mm.o) "_OBJC_CLASS_$_FIRDatabase", referenced from: objc-class-ref in libFirebaseCppDatabase.a(database_ios.mm.o) "_OBJC_CLASS_$_FIRConfiguration", referenced from: objc-class-ref in libFirebaseCppApp.a(app_ios.mm.o) "_OBJC_CLASS_$_FIRApp", referenced from: objc-class-ref in libFirebaseCppApp.a(app_ios.mm.o) "_OBJC_CLASS_$_FIRTransactionResult", referenced from: objc-class-ref in libFirebaseCppDatabase.a(database_reference_ios.mm.o) "_OBJC_CLASS_$_FIROptions", referenced from: objc-class-ref in libFirebaseCppApp.a(app_ios.mm.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

请我跪下乞求

Answer 1

打开Unity-iPhone.xcworkspace而不是Unity-iPhone.xcodeproj

如果没有Unity-iPhone.xcworkspace ，运行pod install

如果 cocoapods 有问题，请重新安装 cocoapods。
