在XCode中構建項目的問題 - ProcessPCH錯誤

Question

在試圖將Facebook SDK安裝到項目中後，我一直在編譯項目時出現問題。我已將代碼恢復到之前的狀態，但是我仍然收到與「ProcessPCH」相關的錯誤消息。我檢查了目標設置，但仍找不到解決此問題的任何解決方案。

錯誤代碼如下所示：

如果任何人有一個解決方案，這將不勝感激。

現在問題已解決。儘管我對自己不感到驕傲，但我很高興解決了這個問題。

在我的情況下，我不小心評論了我的AppDelegate頭文件的@end，導致XCode項目完全失敗。

我仍然很不確定爲什麼當時說我的失敗與MKNetworkKit中的文件有關，但我只能建議你檢查所有的文件，如果清理構建/派生數據不起作用。重新安裝XCode絕對不是一個理想的解決方案。
