我的应用启动后，其他应用的音乐停止播放

Question

When I start my app music from other apps stops playing.

I've tried adding the setCategory:AVAudioSessionCategoryAmbient in didFinishLaunchingWithOptions but the music still stops on FIRST launch. If I start the music and goes back to the app with home button the music will continue to play. Is there any workaround for the first launch issue?

Snippet I've added:

// make sure music plays while sounds play.
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[[AVAudioSession sharedInstance] setActive:YES error:nil];

Answer 1

Try this instead:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient withOptions:0 error:nil];

Or this if above doesn't work:

[[AVAudioSession sharedInstance] setActive:NO error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[[AVAudioSession sharedInstance] setActive:YES error:nil];

EDIT:

If none of the above works for you, you should maybe try set another category you see fit together with AVAudioSessionCategoryOptionMixWithOthers if that works for your use-case.

Determines whether audio from this session is mixed with audio from active sessions in other audio apps.
