在我的ARKit应用程序中,我提出了一个模态窗口.当我关闭模态并返回到ARSCNView时,我发现由于此代码,会话暂停:

 override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

        // Pause the view's session
        sceneView.session.pause()
    } 

当我关闭模态并返回到ARKit相机视图屏幕时,此代码被触发:

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        // Create a session configuration
        let configuration = ARWorldTrackingSessionConfiguration()

        // Run the view's session
        sceneView.session.run(configuration)
    }

但是这段代码永远不会恢复会话.屏幕在其读取的最后一张图像上完全冻结.有任何想法吗？

我将viewDidAppear代码更新为以下内容.它仍然卡在相机屏幕上,图像被冻结.

  override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        // Create a session configuration
        let configuration = ARWorldTrackingSessionConfiguration()

        sceneView.session.delegate = self

        if self.isPaused {
            sceneView.session.run(sceneView.session.configuration!)
        } else {
            // Run the view's session
            sceneView.session.run(configuration)
        }


    }
