我有一個非常奇怪的錯誤，我無法弄清楚，我現在確實需要一些幫助。基本上，tableView有三個UITableViewCell子類，它們有自己的原型單元，並出現在它們自己的部分。但是第三部分的原型也出現在第二部分中。奇怪的部分是，在將一些NSLogs放入我的代碼之後，第二節中顯示的單元格（它應該在第三節中）是UITableViewCell的正確子類，但其他原型的內容正在顯示。我不知道爲什麼會發生這種情況。我已經檢查確保原型是正確的子類，並且標識符都是正確的，並且它們是。有沒有人遇到過這個問題？對不起提前多久我cellForRowAtIndexPath:方法是：UITableView從故事板加載錯誤的原型單元格
