如何在场景中添加按钮和标签

Question

I am new in Scenekit and ARKit, I wanted to add button and label inside UIView to the scenekit's scene. I am getting the world coordinates by the hit test to place the view but SCNNode don't have addSubView Method to add view.

I want to achieve following output :

My attempts to achieve this :

func addHotspot(result : SCNHitTestResult, parentNode : SCNNode? = nil) {
    let view = UIView()
    view.backgroundColor = .red

    let material = SCNMaterial()
    material.diffuse.contents = view

    let plane = SCNPlane(width: 100, height: 100)
    plane.materials = [material]

    let node = SCNNode()
    node.geometry = plane

    node.position = result.worldCoordinates
    parentNode?.addChildNode(node)
}

error :

Please suggest the way I can complete it.

To add a UIView object to a scene node, you can assign it to the node's geometry material diffuse content. It will be added to the node and will maintain its position as you move your device around:

DispatchQueue.main.async {
  let view: UIView = getView() // this is your UIView instance that you want to add to the node

  let material = SCNMaterial()
  material.diffuse.contents = view

  node.geometry.materials = [material]
}
