框架错误

Question

我更新了解析框架到最新的版本在我的应用程序，现在我得到错误的TON在我的应用程序，主要是框架相关：

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

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

我已经证实，框架被添加，所以我不确定错误是由什么引起的。

不知道您是否在使用CocoaPods，但如果是这样，我今天在更新时遇到了同样的问题。从最新的更新中删除了'Facebook-iOS-SDK'和'ParseFacebookUtils'。不要深入了解错误，看起来好像链接器错误正在发生。在我Podfile，我只是说：

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

如果不使用的CocoaPods，它可以帮助确保这两个库是在源代码中，清洁和重建。
