我有 viewController 1,它用 ARSCNView 呈现 viewController。在 viewControllers 的事务之间,方向发生了变化,所有的 UI 方向都在该位置,但 ARSCNView 相机视图位于错误的位置

(视图框架在当前位置,但相机视图倒置或向左)

当我将手机旋转到纵向并返回所有外观时。

  • ARSCNView 在自定义视图中

    class MyARSceneView :UIView {
        @IBOutlet private weak var sceneView: ARSCNView!
    
        private func loadViewFromNib() -> UIView {
        let bundle = Bundle(for: type(of: self))
        let nib:UINib = UINib(nibName: self.nibName, bundle: bundle)
        // Assumes UIView is top level and only object in CustomView.xib file
        let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
        return view
        }
    
        ....
    }
    
  • ARViewContoller:

    class ARViewController : UIViewController {
        @IBOutlet weak var arSceneView: FBARSceneView!
    
        override func viewDidLoad() {
            appDelegate.enableAllOrientation = true
            super.viewDidLoad()
        }
    
        func presentARViewController() {
             self.annotationView = UIStoryboard.arViewController()
             viewController.present(annotationView!, animated: true) {
            self.setUpARViewController()
            completion?()
        }
    }
    
  • 在 appDeleagte 中:

    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask
    {
        if  enableAllOrientation == true  {
            return UIInterfaceOrientationMask.allButUpsideDown
        }
        return UIInterfaceOrientationMask.portrait
    }
    

调用 presentARViewController 函数后,会显示新屏幕,但相机视图的方向错误。

方向错误
