框架錯誤

Question

我更新瞭解析框架到最新的版本在我的應用程序，現在我得到錯誤的TON在我的應用程序，主要是框架相關：

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) 

我已經證實，框架被添加，所以我不確定錯誤是由什麼引起的。

不知道您是否在使用CocoaPods，但如果是這樣，我今天在更新時遇到了同樣的問題。從最新的更新中刪除了'Facebook-iOS-SDK'和'ParseFacebookUtils'。不要深入瞭解錯誤，看起來好像鏈接器錯誤正在發生。在我Podfile，我只是說：

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

如果不使用的CocoaPods，它可以幫助確保這兩個庫是在源代碼中，清潔和重建。
