Ios 自定义uitableview崩溃报告NSuitableviewcellAccessbilityElement superview]无法识别的实例选择器

我创建了一个uitableview单元格来显示注释，这个单元格包含一个新的tableview来显示子命令。正常情况下，它工作正常，但有时会突然崩溃，向实例报告[NSUITableViewCellAccessibilityElement superview]无法识别的选择器。我花了很多时间，但无法修复它。我甚至不知道这场车祸什么时候会发生。有人能回答我的问题吗，谢谢

我不知道这里发生了什么。但我很确定问题是由单元格中的tableview引起的。我不知道是否会有人发现这个问题。我不得不说，在可滚动控制器中嵌入可滚动控制器是危险的。我采用了一种正常的方式。

您能提供您的代码吗？显示调用superview的代码-即异常所在的行thrown@Paulw11我从不在代码中调用superview，异常是从内存之类的地方抛出的。真奇怪
