之前是here回答的。事实表明，您需要像本例中那样设置音频 session

UInt32 category = kAudioSessionCategory_MediaPlayback;
OSStatus result = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory,
                                                                                sizeof(category), &category);

if (result){
        DebugLog(@"ERROR SETTING AUDIO CATEGORY!\n");
}

result = AudioSessionSetActive(true);
if (result) {
        DebugLog(@"ERROR SETTING AUDIO SESSION ACTIVE!\n");
}
