FacebookSDK 3.0 - Apple Mach-O鏈接程序錯誤

我正試圖在我的一個應用程序中實現Facebook，因此遵循官方的Facebook教程Hackbook。 https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/FacebookSDK 3.0 - Apple Mach-O鏈接程序錯誤

我實現了所描述的一切，並且沒有收到任何錯誤或警告。但是，當我嘗試構建應用程序時，我得到17個Mach-O鏈接程序錯誤。

重新實現，清潔應用，確保一切之後在那裏，我的想法。我也在另一個應用程序中實現了它，但又重新發現了錯誤。然而，來自Facebook的給定樣本按預期工作。我在互聯網上做了各種各樣的tipps，但他們都沒有工作到目前爲止。也許這裏有人知道一些有關的API並具有很好的提示我:)

您是否嘗試過設備（iPhone/iPad，..）以及？嘗試時有沒有不同的錯誤信息？現在看起來有點像你試圖將模擬器構建與設備庫相鏈接。 – Till 2012-08-11 18:46:02

嘿，我試着用iphone和ipad模擬器，也在我的設備上，但錯誤保持不變。 – Blade 2012-08-11 18:46:46

好吧，那麼......你確定你是否按照關於SDK的鏈接指示（應包含在該框架中）？ – Till 2012-08-11 18:48:32

我認爲你缺少這一行

的NSString * const的FBSessionStateChangedNotification = @「FBSessionStateChangedNotification」;

並添加參考-lsqlite3.0

見https://developers.facebook.com/docs/getting-started/getting-started-with-the-ios-sdk/#project

謝謝，我其實忘了參考。傻我：D – Blade 2012-08-12 13:17:31

謝謝..！這真的幫了我很多 – 2012-09-05 07:32:41

如果你添加'NSString * const FBSessionStateChangedNotification = @「FBSessionStateChangedNotification」;'，但是感謝指向sqlite3.0，你會得到鏈接器錯誤（對於我用3.0 SDK的重複符號）！完全錯過 – cbowns 2012-09-20 22:43:44

我認爲你缺少這

轉到項目 - > BuildPhase->鏈接二進制添加 - > - lsqlite3.0

是的，我發現解決方案：libsqlite3.dylib，我用armv6編譯不是7，所以你下載Xcode dmg文件（超過4.2），並從它提取的lib。
