我正在使用 PHPickerViewControllerDelegate 获取 url。我已经确认我的 url 已正确输入到代码中，但是当我播放视频节点时，没有视频显示并且我没有听到任何声音，所以这不是分层问题。我们可以将此选项称为 1。

更新：我认为我可以通过使用 AVPlayer 来解决问题，所以我尝试了两种额外的方法，（选项 2）将视频文件放入项目中，这有效但不能解决我从本地目录中提取文件的问题。（选项 3）使用本地目录中的视频，但不起作用。SKVideoNode 框显示但没有视频播放。

这告诉我，它与本地目录 url 有关。我需要包括一些隐私的东西，所以视频显示了吗？我很近，但似乎很远。
