遷移到Xcode 4.5後與Reachability相關的未定義符號

我將運行在Xcode 4.2上的Mac中的Xcode項目移動到運行Xcode 4.5的另一個Mac中後，我收到以下錯誤。遷移到Xcode 4.5後與Reachability相關的未定義符號

@Spynet：我冒昧地撤銷了對這個問題的編輯。這不是代碼，而是鏈接器的逐字輸出，並且格式化得很好。 –

看起來你可能已經忘記了包含RestKit。 Add the library，看看你是否仍然有問題。

謝謝@ Inspire48，但庫已添加 – fadd

問題很可能是該項目不包括RestKit。轉到您的目標 - >構建階段 - >鏈接，並確認實際上您有RestKit。

SCError，SCErrorString，...都來自SystemConfiguration.framework，因此您的目標的「Link Binary With Libraries」設置似乎丟失。在Xcode文檔瀏覽器

（「未定義的符號...」鏈接錯誤在很多情況下可以通過查找符號沒有領先解決下劃線。在文檔頁面的頂部找到框架的地方符號被定義）。

我有類似的問題。添加SystemComfiguration.framework後，問題就解決了。

您忘了將SystemConfiguration.framework添加到您的項目中。

嘗試創建一個新的方案。我在Xcode 6.3中看到類似的錯誤信息 - 這爲我解決了它。
