Ios 如何将CoreData（NSManagedObject）设置为AvAudioRecorder的目标？

我可以通过什么方法将NSManagedObject设置为AVAudioRecorder的目标（与NSURL相反）？我想在选择“外部存储”选项的情况下，将微小的声音片段保存为二进制核心数据类型。。。当然，也会播放它们。我已经看到了一些围绕这个主题的问题，似乎有一些正在这样做，但我还没有找到任何核心代码示例。到目前为止，我已经按照本教程成功地录制了基本文件类型：，我只想将其直接带到核心数据

仅供参考-我确实意识到最佳实践是存储URL，然后检索，但如果可能的话，我真的希望直接将二进制文件输入CoreData

谢谢
