解析应用程序ParseFacebookUtils中的框架错误

Question

我将Parse Framework更新为应用程序中的最新版本，现在我的应用程序中出现了很多错误，主要是与Framework相关的：

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_FBSDKAccessToken", referenced from:
      objc-class-ref in ParseFacebookUtilsV4(PFFacebookUtils.o)
      objc-class-ref in ParseFacebookUtilsV4(PFFacebookAuthenticationProvider.o)

      BreakpadPFC_::Initialize(NSDictionary*) in ParseCrashReporting(Breakpad.o)
      BreakpadPFC_::GenerateReport(NSDictionary*) in ParseCrashReporting(Breakpad.o)

我已经确认已添加框架，所以我不确定造成的错误是什么。

不知道您是否使用CocoaPods，但如果是这样，今天更新时我遇到了同样的问题。 从显示的内容中，“ Facebook-iOS-SDK”和“ ParseFacebookUtils”已从最新更新中删除。 无需深入了解错误，就好像发生了链接器错误。 在我的Podfile中，我只是添加了：

pod 'Facebook-iOS-SDK'
pod 'ParseFacebookUtils'

如果不使用CocoaPods，则可能有助于确保这两个库在您的源代码中，进行清理和重建。
