如何在arkit中添加带有手势动作的scnnode中的标签节点和用户图像?

scnnode arkit xcode swift ios

实际上,我正在工作名片图像检测,以显示那里的业务概况。我已经实现了图像检测,平面动画。这是我的问题,当图像检测到与飞机,它应该显示用户名标签,个人资料和网站。我正在尝试显示用户名标签,但我已经在scntext中完成了。如何使用scnnode标签用户iamge?

这是我尝试的代码:

guard let imageAnchor = anchor as? ARImageAnchor else {return}
if let imageName  = imageAnchor.referenceImage.name {

    print(imageName)

    if imageName == "card" {

   //                let planeGeometry = SCNPlane(width: 25, height: 25)
   //                planeGeometry.firstMaterial?.isDoubleSided = true
  //                planeGeometry.firstMaterial?.diffuse.contents = UIColor.blue.withAlphaComponent(0.5)
         //--
        let plane = SCNPlane(width: 4,
                                 height: 10)
        plane.firstMaterial?.diffuse.contents = UIColor.init(red: 0, green: 189, blue: 255, alpha: 0.88)
        plane.cornerRadius = 0.25

        let planeNode = SCNNode(geometry: plane)
        planeNode.opacity = 0.25
        planeNode.eulerAngles.x = -.pi / 2
   //                planeNode.position = SCNVector3(x:0, y:0, z:2)
        planeNode.runAction(SCNAction.moveBy(x: 0, y: 0, z: 5, duration: 0.5))


        let nameText = SCNText()
        nameText.firstMaterial?.diffuse.contents = "Gowdhaman"
        nameText.font = UIFont(name: "Avenir-medium", size: 16)
        nameText.firstMaterial?.diffuse.contents = UIColor.red
        nameText.firstMaterial?.diffuse.contents = SCNVector3.init(0, 0, 0)
     //            nameText.firstMaterial?.diffuse.contents =

     //                nameText.firstMaterial?.diffuse.contents = SCNAction.moveBy(x: 0, y: 0, z: 5, duration: 1)

        let nameLabelNode = SCNNode(geometry: nameText)
        let eulerAngles = 
    self.sceneView.session.currentFrame?.camera.eulerAngles

        nameLabelNode.eulerAngles = SCNVector3((eulerAngles?.x)!, 
   (eulerAngles?.y)!, (eulerAngles?.z)! - .pi/6)

        planeNode.addChildNode(nameLabelNode)
        node.addChildNode(planeNode)

        self.sceneView.scene.rootNode.addChildNode(node)



    }

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

        let node = SCNNode()

        ......

        // create a plane to contain the image
        let profilePlane = SCNPlane(width: 0.035, height: 0.035)

        // Add the profile picture file in your assets folder to the contents of your plane
        profilePlane.firstMaterial?.diffuse.contents = "ProfilePictureName"

        let profilePlaneNode = SCNNode(geometry: profilePlane) 

        node.addChildNode(profilePlaneNode)

}
