我似乎無法使這個自定義單元格的tableView工作。我得到一個運行時錯誤TableView在未捕獲異常'NSUnknownKeyException'下崩潰，這個類不是密鑰x的關鍵值編碼。
終止應用程序由於未捕獲的異常「NSUnknownKeyException」， 原因：「[setValue方法：forUndefinedKey：]：此類不是關鍵 值編碼兼容的關鍵causeCampaignDescription。」
奇怪的是，該屬性不是那樣調用。這是細胞文件MainViewControllerTableViewCell

- 應用崩潰如果線路
reloadData未被註釋（I甚至不知道什麼時候和如果我應該使用這個） - 如果我設置標籤，你不能看到任何東西在scree N，我看到空白卡，但同樣，只要我去掉
reloadData崩潰 - 有沒有
causeCampaignDescription，現在它被稱爲causeDescription，所以我不知道爲什麼錯誤不斷提的是，現場 - 數據
desc是確定因爲我打印它，它有正確的內容，所以它不是
可能是什麼問題？
在代碼中搜索'causeCampaignDescription'。您可能忘記將它從界面構建器中刪除（Storyboards/Xibs） – sheetal
您將'causeCampaignDescription'重命名爲'causeDescription'，但您的故事板或NIB最有可能仍然提及舊名稱。去IB的那個領域，檢查那個控制點的出口。我敢打賭，你會發現那個舊名字仍然在那裏引用。 – Rob
