最简单（尽管未记录）的方法是将视图控制器支持的 UIView 设置为 SCNPlane上材质的漫反射内容（或任何其他几何体，但由于显而易见的原因，它最适合飞机）。

The simplest (although undocumented) way to achieve that is to set a UIView backed by a view controller as diffuse contents of a material on a SCNPlane (or any other geometry really, but it works best with planes for obvious reasons).

let plane = SCNPlane()
plane.firstMaterial?.diffuse.contents = someViewController.view
let planeNode = SCNNode(geometry: plane)

你必须将视图控制器保留在某处，否则它会继续被释放，飞机将不可见。只使用 UIView 而不使用任何 UIViewController 将引发错误。

You will have to persist the view controller somewhere otherwise it's going to be released and plane will not be visible. Using just a UIView without any UIViewController will throw an error.

关于它的***的事情是它保留了所有的手势，实际上只是作为一个简单的视图。例如，如果您使用 UITableViewController 的视图，您将能够在场景中向右滚动。

The best thing about it is that it keeps all of the gestures and practically works just as a simple view. For example, if you use UITableViewController's view you will be able to scroll it right inside a scene.

我还没有在iOS 10及更低版本上测试它，但到目前为止它一直在iOS 11上运行。适用于普通的SceneKit场景和ARKit。

I haven't tested it on iOS 10 and lower, but it's been working on iOS 11 so far. Works both in plain SceneKit scenes and with ARKit.
