UItableviewcell故障

Question

所以有时候回到我的游戏主菜单时，我会受到非常特别的欢迎。从图中可以看出，我已经复制了UIView表外的单元格。现在起初我认为这是基于内存问题的图形损坏，然后我发现你可以与它们进行交互，它们是有效的单元格...而不是鬼图像，它们响应代码，所以我做了一点搜索，虽然我的桌子卡在编辑模式或其他什么东西所以我称之为setediting：我无处可去。它仍然困扰着我。

有没有人首先想到可能导致这种情况的原因？它不会一直发生，但它似乎只会发生......如果我从它上面的另一个视图弹回到这个屏幕的话。我也无法一直复制它，因此很难修复并知道是什么导致它。

请记住，我可能正在做某事或不做我未提及的事情，所以不要忘记问你认为相关的一切，我很乐意通知你。
