我正在尝试在 UIImagePicker 中的视频捕获会话上覆盖视图。覆盖效果很好，但是当应用程序进入用户可以“重拍”、“播放”或“使用视频”的屏幕时，应用程序崩溃并给出错误：

2017-04-16 21:33:04.129212-0400 ChugMug [429:59833] libMobileGestalt MobileGestalt.c:2690: statfs(/mnt4): 没有这样的文件或目录 2017-04-16 21:33:04.129871-0400 ChugMug [ 429:59833] libMobileGestalt MobileGestalt.c:2587：SInt64 NANDSize()：找不到磁盘 0 的 kIOMediaSizeKey！2017-04-16 21:33:09.352085-0400 ChugMug [429:60065] [MediaRemote] 错误操作需要已注册客户端回调。请求播放队列

代码很简单，当覆盖层被注释掉时，视频预览屏幕和按钮工作正常，但是当覆盖层存在时，应用程序冻结在以下屏幕：在此处输入图像描述

这是相机和叠加层的代码：

func startMediaBrowserFromViewController(viewController: UIViewController, usingDelegate delegate: UINavigationControllerDelegate & UIImagePickerControllerDelegate) -> Bool {
    // 1
    if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum) == false {
        return false
    }

    // 2
    let mediaUI = UIImagePickerController()
    mediaUI.sourceType = .savedPhotosAlbum
    mediaUI.mediaTypes = [kUTTypeMovie as NSString as String]
    mediaUI.allowsEditing = true
    mediaUI.delegate = delegate

    // 3
    present(mediaUI, animated: true, completion: nil)
    return true
}

func startCameraFromViewController(viewController: UIViewController, withDelegate delegate: UIImagePickerControllerDelegate & UINavigationControllerDelegate) -> Bool {

    if UIImagePickerController.isSourceTypeAvailable(.camera) == false {
        return false
    }


    cameraController.sourceType = .camera
    cameraController.mediaTypes = [kUTTypeMovie as NSString as String]
    cameraController.allowsEditing = false
    cameraController.delegate = delegate
    cameraController.showsCameraControls = true


    //customView stuff
    let customViewController = CustomOverlayViewController(
        nibName:"CustomOverlayViewController",
       bundle: nil
    )
    let customView = customViewController.view //as! CustomOverlayView
   customView?.frame = cameraController.view.frame

    present(cameraController, animated: true, completion: {
        self.cameraController.cameraOverlayView = customView
        customViewController.cameraLabel.text = "Camera Label"
        self.cameraController.startVideoCapture()
    })

    return true
}

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let mediaType = info[UIImagePickerControllerMediaType] as! NSString
    dismiss(animated: true, completion: nil)

    // Handle a movie capture
    if mediaType == kUTTypeMovie {
        guard let path = (info[UIImagePickerControllerMediaURL] as! NSURL).path else { return }
        if UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path) {
            UISaveVideoAtPathToSavedPhotosAlbum(path, self, nil, nil)
        }
    }
}

我不知道是什么导致了这个奇怪的错误，也找不到类似的东西。我希望有一个人可以帮助我。
