ARKit插入VC捕获事件Swift 4

Question

我在sceneView: ARSCNView中放了一个VC

但是SecondVC的事件不能工作，当用户按下以下按钮时，我需要更改文本，这是我的代码：

class ViewController: UIViewController, ARSCNViewDelegate,ARSessionDelegate {

   let vc = SecondVC()
    var viewVC = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()

// I Get te reference to my view

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let viewController = storyboard.instantiateViewController(withIdentifier :"SecondVC") as! SecondVC
        viewVC = viewController.view

        // Set the view's delegate
        sceneView.delegate = self
        sceneView.session.delegate=self

    }
}

当我发现一个锚并将VC放到场景中时，我就触发了这个事件。

    func renderer(_ renderer: SCNSceneRenderer, nodeFor anchor: ARAnchor) -> SCNNode? {


      if self.detectedDataAnchor?.identifier == anchor.identifier {

              let node = SCNNode()
               let plane = SCNPlane(width: 0.2, height: 0.2)
                plane.firstMaterial?.diffuse.contents = viewVC
                let planeNode = SCNNode(geometry: plane)
                planeNode.opacity = 0
                node.addChildNode(planeNode)
              return node
       }
    return nil
}

在我的SecondVC课上：

@IBOutlet weak var label: UILabel!

    @IBAction func pressButton(_ sender: UIButton) {

        label.text = "I changed"
    }

但在主视图中从未调用此操作：

最后我找到了解决办法

1我在场景中创建了xib文件2获取对文件3的访问，如下所示：

let node = SCNNode()
let plane = SCNPlane(width: 0.2, height: 0.2)
            plane.firstMaterial?.diffuse.contents = viewToShow
            let planeNode = SCNNode(geometry: plane)
            node.addChildNode(planeNode)

return node

而且起作用了！当点击按钮时，我可以更改文本。
