推荐答案

您可能需要设置音频会话类别。来自iPhone应用程序编程指南

You may need to set an audio session category. From the "iPhone Application Programming Guide"

类别是为$ b标识音频行为的键$ b申请。通过设置一个类别，你可以将你的音频意图表示为 iPhone OS，例如你的音频是否应该在屏幕锁定时继续。

A category is a key that identifies a set of audio behaviors for your application. By setting a category, you indicate your audio intentions to iPhone OS, such as whether your audio should continue when the screen locks.

每个类别的详细信息都列在音频会话类别

The details about each category are listed at "Audio Session Categories"
