正如问题所述，我试图在SpriteKit内调用UITextField接受用户输入的名称。我看过这里的许多帖子，但似乎都不适用于我所面临的问题。我要做的第一件事是将UITextField声明为类变量，因此稍后可以通过执行以下操作将其从单独的函数中从视图中删除：
let nameEntry = UITextField(frame: CGRect(origin: CGPoint(x: 800, y: 875), size: CGSize(width: 600, height: 200)))
然后我通过声明添加UITextField：
self.view?.addSubview(nameEntry)
但是，文本框未显示在我的场景中。我已经在层次结构视图中对其进行了研究，但它根本不存在。我对使用SceneKit缺乏经验，所以很好奇我做错了什么。预先感谢任何尝试提供帮助的人！
以更好地了解我的工作方式：
class Tutorial : SKScene{
let nameEntry = UITextField(frame: CGRect(origin: CGPoint(x: 800, y: 875), size: CGSize(width: 600, height: 200)))
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
//insert many lines of code here
self.view?.addSubview(nameEntry)
}
}
编辑：这是到目前为止的所有代码。

SpriteKit的SKSKScene存在于UIKit的SKView内部。也就是说，整个Spritekit场景基本上是应用程序中单个视图的支持层。如果要在UIKit层中执行操作，则更有意义的是在视图控制器级别执行这些操作并将职责委派回去。因此，例如，如果您想要一个textField，则可以在界面构建器中对其进行设置并将其隐藏，然后仅在场景请求时显示它。
如果您不想这样做，您仍然可以在执行操作时进入视图并从SKScene添加子视图（它糟糕的OOP可以扩展并更改您的父级，但是UIKit中没有任何功能）阻止您执行此操作）。您遇到的最可能的问题是SpriteKit和UIKit中的坐标系不同，并且实际上是颠倒的。因此，您不能仅将SKScene坐标用于UIViews。您需要转换。 SKView有一系列可以为您进行数学计算的方法：SKView.convert(:to:) SkView.convert( :from:)。请注意，这只会使您到达SKView。然后，您需要使用UIKit的convert方法转换为viewController.view坐标。
我认为，如果您将UIKit内容留在UIKit层中，而只是让viewController和scene来回传递相关信息，那么它就不会那么混乱了。
