This is a duplicate of Record Internal Sound iPhone SDK.
这是Record Internal Sound iPhone SDK的副本。
And no, you cannot do it by any public API - using a non-public API will result in your app getting rejected and not allowed into the Apple App Store.
不，您不能通过任何公共 API 来做到这一点 - 使用非公共 API 将导致您的应用被拒绝并且不允许进入 Apple App Store。

Have you tried getting the stream URL for BBC Radio and record directly from the stream? If you can find the right URL, something like AudioStreamercould help you actually stream the audio. Then it is only up to you to record what you get from the stream. This is a much more realistic approach to accomplishing your goal.
您是否尝试过获取 BBC Radio 的流 URL 并直接从流中录制？如果您能找到正确的 URL，则AudioStreamer 之类的东西可以帮助您实际流式传输音频。然后只由您来记录您从流中获得的内容。这是实现目标的更现实的方法。
