从另一个视图控制器切换回ARSCNView后，ArKit失去了世界定位

Question

我有两个ViewControllers，一个带有ARSCNView，另一个带有一些数据。从第二个视图控制器切换回第一个视图控制器时，ARSession无法正常工作。

我已经尝试保存世界地图，并在单击“后退按钮”从一个视图到另一个视图之后将其还原。

我还尝试了在堆栈溢出时已经在此处提供的Session的所有重置内容

我确实覆盖了这些方法：

override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        // Pause the view's session
        sceneView.session.pause()
        print("view did disappear")
        sceneView.session.getCurrentWorldMap { (worldMap, error) in
            guard let worldMap = worldMap else {
                print("Error getting current world map.")
                return
            }

            do {
                try self.archive(worldMap: worldMap)
                DispatchQueue.main.async {
                    print("World map is saved.")
                }
            } catch {
                fatalError("Error saving world map: \(error.localizedDescription)")
            }
        }
    }


override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        let worldMapData = retrieveWorldMapData(from: worldMapURL)
        var worldMap: ARWorldMap? = nil
        if worldMapData != nil {
            worldMap = unarchive(worldMapData: worldMapData!)
        }
        resetTrackingConfiguration(with: worldMap)
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        // self.mode = .showFeaturePoints
    }

    func resetTrackingConfiguration(with worldMap: ARWorldMap? = nil) {
        let configuration = ARWorldTrackingConfiguration()
        configuration.planeDetection = [.horizontal]

        let options: ARSession.RunOptions = [.resetTracking, .removeExistingAnchors]
        if let worldMap = worldMap {
            configuration.initialWorldMap = worldMap
            print("Found saved world map.")
        } else {
            print("Move camera around to map your surrounding space.")
        }

        sceneView.debugOptions = [.showFeaturePoints, .showWireframe]
        sceneView.session.run(configuration, options: options)
    }

我只希望我的ARSession在按下UINavigation的后退按钮后能够正常工作
