我目前正在开发一款游戏，包含各种关卡和菜单场景。当前关卡创建了一个问题标签和答案按钮，即使在关卡完成后，你导航到另一个场景，按钮和问题仍然在场景上，无论你导航到哪个场景。
我希望得到一个解决方案，只有按钮和标签出现在指定的场景，不出现在其他场景，除非说明。
提前谢谢你。
我认为你没有理解这里的所有权模型。ViewController拥有它的视图。视图拥有SKView而SKView拥有SKScene。有一个从SKScene到它的SKView的反向指针，你正在使用它来添加一个UIKit StakcView到Scene的父视图。因为UIKit位于SKScene的顶部，你的按钮总是可见的。正确的架构是视图应该添加和管理它自己的子视图。每当它加载一个新的SKScene时，它应该确定场景需要什么UI，然后隐藏任何不应该显示的UI。您可以通过在相关视图上设置. ishidden来实现。
