信息[UIImagePickerController.InfoKey.mediaURL]在从摄像机卷（Swift）选择视频时一直返回零

我有一个imagePickerController，但无法获取我从摄像机卷中选择的视频的url，这过去是有效的，但现在我总是看到从mediaURL返回一个nil值

上述函数在选择图像的情况下正常工作，但似乎总是失败，并为let videoUrl=info[UIImagePickerController.InfoKey.mediaURL]返回nil作为？URL，导致应用程序崩溃。非常感谢您提供的任何帮助/解释

请检查与您类似的问题：

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]){

    picker.dismiss(animated: true, completion: nil)
    NewLookMediaImage.layer.borderWidth = 1
    //NewLookMediaImage.layer.borderColor = nil
    NewLookMediaImage.layer.backgroundColor = nil

    let mediaType = info[UIImagePickerController.InfoKey.mediaType] as! CFString
    NewLookMediaButton.setImage(nil, for: .normal)
    //NewLookMediaButton.backgroundColor = UIColor(.black)
    switch mediaType {
      case kUTTypeImage:
        // Handle image selection result
        print("Selected media is image")
        GlobalVideoURL = nil
        let editedImage = info[UIImagePickerController.InfoKey.editedImage] as! UIImage
        NewLookMediaImage.image = editedImage
        PlayButton.isHidden = true

      case kUTTypeMovie:
        // Handle video selection result
        print("Selected media is video")
        let videoUrl = info[UIImagePickerController.InfoKey.mediaURL] as? URL

        let thumnailImage = ThumbnailImageForFileURL(FileURL: videoUrl!)
        GlobalVideoURL = videoUrl
        NewLookMediaImage.image = thumnailImage
        //lets give our video thumbnail a play button
        PlayButton.isHidden = false

      default:
        print("Mismatched type: \(mediaType)")
    }
}
