Question

我希望你今天过得好！

我正在尝试创建一个非常简单的应用程序，它具有较小的社交扩展。当用户将音频消息分享到我的应用程序时，我希望我的应用程序检测它是否是音频。它只适用于音频附件，但我无法实现。例如，如果我将'kUTTypeAudio'更改为'kUTTypeImage'并且我正在尝试将图像共享到我的应用程序 - 它可以正常工作。它会检测图像类型，但是使用音频消息它不起作用。在我的应用程序中，我不需要带有发布按钮和所有内容的ShareView UI。我这就是我取消View的原因，只是向用户显示一条消息并提示消息。

我的问题是： 1.如何检测来自Whatsapp的音频消息？ 2.接下来，如何使用此音频消息？我需要将它变为变量然后满足我的需求或者什么？谢谢你们！

这是我的ShareViewController.swift：
