如果這是一個轉發，我很抱歉，但我一直在網上搜索，似乎無法找到任何有效的東西。我有一個鍛鍊列表，顯示在捆綁中的plist中收集的tableview中。還有一個單獨的選項卡，允許用戶構建自己的鍛鍊並將其保存在文檔文件夾plist文件中。保存後，它們將被添加到表格視圖中。在模擬器中，everyuhting正常工作。但在實際的設備上，除非我長時間關閉程序，從xcode重新加載程序或關閉手機，否則不會更新。我曾嘗試將[[self tableview] reload]添加到「viewDidLoad」，「viewWillappear」和「viewDidAppear」，它們都不起作用。再次保存文件，更新在模擬器中工作，並且不會立即在手機中更新。有什麼建議麼？謝謝。tableview將不會更新電話
編輯：我知道它是一個長一段代碼，而應該是直線前進（希望笑）

是的，這是問題=）。我只在viewDidLoad中加載了plist文件。在模擬器上，它非常爽快，但在電話上，它不是。將我所有的代碼移動到viewDidAppear，並且一切都是excelsior = D。非常感謝。 – TigerCoder
