Parse 应用程序 ParseFacebookUtils 中的框架错误

Question

我在我的应用程序中将 Parse 框架更新为最新版本，现在我的应用程序中出现大量错误，主要与框架相关：

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)

我已经确认添加了Framework，所以不知道是什么原因造成的。

不确定您是否使用 CocoaPods，但如果是，我今天在更新时遇到了同样的问题。从它的显示来看，“Facebook-iOS-SDK”和“ParseFacebookUtils”已从最新更新中删除。如果不深入您的错误，看起来好像正在发生链接器错误。在我的 Podfile 中，我只是添加了：

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

如果不使用 CocoaPods，确保这两个库在您的源代码中、清理并重建可能会有所帮助。
