ios - ARSKView 在关闭 ViewController 时不释放内存

Question

我正在创建一个使用 ARSKView 的应用程序。我发现它在关闭 ViewController 时没有释放内存。我在我的代码中找不到任何问题。这是我使用 ARSKView 的代码。

class ARViewController: UIViewController, ARSKViewDelegate {

    weak var sceneView: ARSKView?

    override func viewDidLoad() {
        super.viewDidLoad()
        sceneView = ARSKView(frame: self.view.frame)
        self.view.addSubview(sceneView!)
        sceneView?.delegate = self

        let scene = CustomScene(size: view.frame.size)
        scene.sceneDelegate = self
        sceneView?.presentScene(scene)
    }

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

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        sceneView?.session.pause()
    }

    var configuration = ARWorldTrackingConfiguration()
    func activateARView() {
        configuration.worldAlignment = .gravityAndHeading
        sceneView?.session.run(configuration)
    }

}

Controller 刚刚暂停，您可以尝试将 Controller 设置为“nil”，只需确保在此之前清除所有依赖项即可。
