我知道這個問題以前已經問過，但我的是不同的。我的應用程序有一個添加按鈕和編輯按鈕，可以刪除/添加表格視圖。我希望每個由用戶創建的單元都轉到相同的視圖。我一直在尋找代碼，但我找不到它。順便說一句____只是一個佔位符。表格編碼位於應用程序委託中，而且我有第二個視圖控制器用於單擊行時加載的視圖。從表格視圖單元格添加視圖

這裏有幾點提示：首先，我不明白除了添加/刪除表格視圖的按鈕...用戶創建的應用程序是你在說什麼？其次，開發的重點不在於「爲代碼尋找無處不在」。第三，國際海事組織用___取代班級的部分名稱頗爲自命不凡，就像你的應用程序太棒了，我們甚至無法知道最細微的細節;只要刪除該名稱的部分，如果它是如此機密...最後，我希望你使用ARC ... – EmilioPelaez
每個細胞*我的壞。而且我正在尋找代碼，因爲不幸的是我無法將它從我的屁股中拉出來。第三，誰關心班級的名字，你知道這意味着什麼嗎？那麼你很好。什麼是ARC？ –
