我遇到了一個神祕的核心數據崩潰，通過我的應用程序中的崩潰報告，我很難提出一個理論。沒有繁殖步驟，沒有明顯的原因，但它發生了幾千次。崩潰報告相當含糊，但似乎發生在NSManagedObject通過屬性分配給另一個？任何理論將不勝感激。神祕的核心數據錯誤崩潰

在你的代碼中有沒有在不同線程之間共享NSManagedObjects的地方？例如，您在主線程上獲取對象，然後將其放入dispatch_async（background_queue ...）進行處理。或者，也許你訪問NSManagedObjectContext是從其他線程在主線程上創建的？ –
據我所知，並沒有做很多工作來避免這種事情。 –
@MishaKarpenko可能是正確的道路。這聞起來像是一個線程問題。像這樣的錯誤錯誤通常在線程邊界被違反時發生。 –
