我在應用程序的關鍵階段得到這一個錯誤。 這種情況是,MainView使用謂詞「User ==%@」currentUser在主視圖中獲取實體「Category」的列表。iCloud - 核心數據同步問題
此頁面通過icloud在設備間同步。
有一個用戶< ----->類別< ---- >>字段< --------- >>條目(時間戳,值)。 < < ------------>用戶 唯一的區別在於,條目可以屬於不同的用戶。因此是最後一次關係。
當我做添加一個「入口」的實體,它創造了當地罰款,但是當日志中接收設備到達(通過iCloud的)......我得到這個:

我用同樣的上下文,我不知道這裏發生了什麼...當這些日誌到達時,其他的stuf沒有工作..
請指點我正確的方向!
謝謝
是的,顯然我添加的上下文沒有正確初始化。我多麼跛腳! – jasonIM 2012-02-21 14:52:06
