ios - 实现 iPod 播放

Question

当我的应用程序正在运行时，如何让 ipod 播放继续？

Answer 1

在启动时，您需要AudioSession通过调用

AudioSessionInitialize(NULL,NULL,NULL,NULL);

然后将您的音频类别设置为kAudioSessionCategory_AmbientSound，就像这样

UInt32  sessionCategory = kAudioSessionCategory_AmbientSound;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
AudioSessionSetActive(true);

Answer 2

I'm pretty sure that it has nothing to do with your app (i.e. a special background service runs for the ipod), but i could be wrong...
