推荐答案

您应该阅读音频会话编程指南，您的要求无法满足。接到电话或系统警报后，您的音频会话将被中断。没有其他办法了。您的应用程序在通话期间无法播放声音。它不会杀死你的应用程序，但是你可以在中断开始/结束时收到通知，以便优雅地做出反应。文档的相关部分（在处理音频中断中）：

You should read the Audio Session Programming Guide, your requirements are impossible to meet. On receiving phone calls or on system alarms your audio session is interrupted. There is no way around it. Your application cannot play sound during the call. It does not kill your app however, you can get notifications on interruption begin/end so as to react gracefully. Relevant bit of the document (in "Handling Audio Interruptions"):

An audio interruption is the deactivation of your application’s audio session—which immediately stops or pauses your audio, depending on which technology you are using. Interruptions happen when a competing audio session from a built-in application activates and that session is not categorized by the system to mix with yours. After your session goes inactive, the system sends a "you were interrupted" message which you can respond to by saving state, updating the user interface, and so on.
