Objective c 为什么我只给addChild打过一次电话，程序就崩溃了？

为什么会在那里坠毁？错误显示我已经给“addChild”打了两次电话，但我显然没有。有人能解决这个问题吗？我已经试过把它放到一个场景中，然后把当前场景换成新生成的场景

这是全班同学。

还有其他地方可以添加孩子吗？@RamyAlZuhouri不，我没有在其他地方添加过。我使用control find查找[self-addChild:playBasicButton]，但什么也没找到。你想让我为那个类粘贴我的全部代码吗？很难说。。。唯一的方法是上传并发布整个项目，因为从代码中我看不到任何可能导致问题的东西。@RamyAlZuhouri我已经用包含该代码的类编辑了我的问题。你不必担心其他的课程。
