Ios 无法检索摄像机滚动雨燕5中视频的URL

以下是我的代码：

@IBAction func selectVideoButton(_ sender: UIButton) {
    let videoPicker = UIImagePickerController()
    videoPicker.sourceType = UIImagePickerController.SourceType.photoLibrary
    videoPicker.mediaTypes = [kUTTypeImage as String, kUTTypeMovie as String]
    videoPicker.delegate = self
    present(videoPicker, animated: true, completion: nil)
}


func retrieveURL(_picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
    if let videoURL = info[.mediaURL] {
        print("Here is the URL: \(videoURL)")
        return
    }
}

我没有收到任何错误，应用程序在选择视频后也不会崩溃，它似乎什么都没做。抱歉，如果在某个地方有此问题的答案，无法找到与swift 5或有效的相关的答案

我尝试将“Any”改为字符串，然后相应地修改videoURL，但也没有效果。

您需要正确的委托方法

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

    if let videoURL = info[.mediaURL] {
        print("Here is the URL: \(videoURL)") 
    }
    picker.dismiss(animated:true,completion:nil) // add this 
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
   let videoURL = info[UIImagePickerControllerMediaURL] as? URL
   print(videoURL)
   imagePickerController.dismissViewControllerAnimated(true, completion: nil)
}
