尝试构建我的xcode项目时出现GTMSessionFetcherService链接器错误

Question

我正在使用Cocoapods来安装最新的GPG并使用最新的XCode 7.3和iOS SDK 9.3但是我无法完成我的项目的构建并且遇到了这些我无法解决的5个链接器错误:

 "_OBJC_CLASS_$_GSDK_GTMSessionFetcherService", referenced from:
      objc-class-ref in gpg(GIPNetworkImage.o)
   objc-class-ref in libSignIn_external.a(GIDSignIn.o)

  "_GSDK_kGTMSessionFetcherStatusDomain", referenced from:
      -[GSDK_GTMOAuth2SignIn authCodeObtained] in libGTMOAuth2_external_external.a(GTMOAuth2SignIn.o)
  "_GSDK_GTMSessionFetcherAssertValidSelector", referenced from:
      -[GSDK_GTMOAuth2Authentication authorizeRequest:delegate:didFinishSelector:] in libGTMOAuth2_external_external.a(GTMOAuth2Authentication.o)
      -[GSDK_GTMOAuth2SignIn initWithAuthentication:authorizationURL:delegate:webRequestSelector:finishedSelector:] in libGTMOAuth2_external_external.a(GTMOAuth2SignIn.o)
  "_OBJC_CLASS_$_GSDK_GTMSessionFetcher", referenced from:

      objc-class-ref in libGTMOAuth2_external_external.a(GTMOAuth2SignIn.o)
      objc-class-ref in gpg(GPGClearcutLogger.o)
      objc-class-ref in libSignIn_external.a(GIDSignIn.o)
      objc-class-ref in libSignIn_external.a(GIDRuntimeConfigFetcher.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我甚至试图在我的项目中添加GTMSessionFetcherService源,但似乎无法解决这个问题.任何的想法？

谢谢

Answer 1

在尝试集成Google登录时,我遇到了一个非常类似的构建问题.在非的CocoaPods指令提添加GoogleSignIn.framework到您的项目,但他们不告诉你,你需要在框架的其余部分的登录链接SDK,以及:

GoogleAppUtilities.framework
GoogleAuthUtilities.framework
GoogleNetworkingUtilities.framework
GoogleSignIn.framework
GoogleSymbolUtilities.framework
GoogleUtilities.framework

Answer 2

您所要做的就是从Google+ iOS SDK添加 到库GoogleOpenSource.framework

然后

添加将GoogleOpenSourcerobovm.xml

最后确保GoogleSignIn robopod存在
