popover下视图上的活动UI导航

Question

我有一个UI，其中SCNView在后台，WKWebView在前台以.popover的形式呈现。视图由单独的视图控制器控制。当用户按下铃声按钮时，WKWebView就会出现(见所附屏幕)。SCNView启用了标准摄像头控制。

目前，当WKWebView弹出窗口出现时，SCNView将变得无响应。轻拍WKWebView外部的手势会将其关闭，其他手势将被忽略，因此当SCNView弹出窗口可见时，用户无法控制WKWebView摄像头。如何在出现WKWebVIew弹出窗口时使SCNView响应？仅当按下时，我如何才能关闭？

使用的代码如下：

class MainVC: UIViewController, UIPopoverPresentationControllerDelegate {
    @IBOutlet weak var scnView: SCNView!
    @IBOutlet weak var bellBtn: UIButton!
    var myWebViewVC: MyWebViewVC!    
    override func viewDidLoad() {
        super.viewDidLoad()
        let scene = SCNScene(named: "art.scnassets/DemoScene.scn")!
        let scnView = sceneView
        scnView!.scene = scene
        scnView!.allowsCameraControl = true
    }
    @IBAction func onBellBtnPressed(_ sender: UIButton) {
        myWebViewVC.modalPresentationStyle = .popover
        myWebViewVC.popoverPresentationController?.delegate = self
        present(myWebViewVC, animated: true, completion: nil)
        myWebViewVC.popoverPresentationController?.sourceView = sender
        myWebViewVC.popoverPresentationController?.sourceRect = sender.bounds
    }
}

MyWebViewVC只关心视图的大小。文件中不会实现任何其他自定义修改。

好的。因此，解决方案主要与视图控制器的popoverPresentationController参数有关。这是documentation。要在呈现为.popover的视图下启用对视图的控制，您需要通知它将在出现popover时响应的视图。传球的顺序是从上到下。下面的代码和passThrough数组使其工作。

class MainVC: UIViewController, UIPopoverPresentationControllerDelegate {
    @IBOutlet weak var scnView: SCNView!
    @IBOutlet weak var bellBtn: UIButton!
    @IBOutlet weak var dotBtn: UIButton!
    var myWebViewVC: MyWebViewVC!    
    override func viewDidLoad() {
        super.viewDidLoad()
        let scene = SCNScene(named: "art.scnassets/DemoScene.scn")!
        scnView!.scene = scene
        scnView!.allowsCameraControl = true
    }
    @IBAction func onBellBtnPressed(_ sender: UIButton) {
        activeUiNavigationUnderPopover()
    }
    func activeUiNavigationUnderPopover () {
        myWebViewVC.modalPresentationStyle = .popover
        myWebViewVC.popoverPresentationController?.delegate = self
        if let pop = myWebViewVC.popoverPresentationController {

                var passthroughViews: [AnyObject]?
                    passthroughViews = [dotBtn, scnView]
                    pop.passthroughViews = NSMutableArray(array: passthroughViews!) as? [UIView]
                    pop.permittedArrowDirections = .any
                    pop.delegate = self
        }
        present(myWebViewVC, animated: true, completion: nil) 
        myWebViewVC.popoverPresentationController?.sourceView = sender
        myWebViewVC.popoverPresentationController?.sourceRect = sender.bounds
    }
}
