自定義uitableview崩潰報告NSuitableviewcellAccessbilityElement超級查看]無法識別的選擇器實例

Question

我做了一個uitableview單元格來顯示註釋，並且這個單元格包含一個新的tableview來顯示子註釋。通常它工作正常，但有時它會突然崩潰，報告[NSUITableViewCellAccessibilityElement superview]無法識別的選擇器實例。我花了很多時間，但無法修復它。我甚至不知道什麼時候會發生這種事故。任何人都可以回答我的問題，thx！

我不知道這裏發生了什麼。但我很確定問題是由單元格中的tableview造成的。我不知道是否會有人發現這個問題。我不得不說，將可滾動控制器嵌入可滾動控制器是危險的。我已經適應了一種正常的方式。
