AVAudioPlayer with MPMusicPlayerController

问题

I have music playing within my application using a MPMusicPlayerController, using iPodMusicPlayer (also tried applicationMusicPlayer). When I play a sound using AVAudioPlayer my music from my MPMusicPlayerController will stop. Is there a way to have the MPMusicPlayerController and the AVAudioPlayer play sounds simultaneously?

回答1:

Hey, found the solution on the web.

Write these 2 lines somewhere, I did it in application:didFinishLaunchingWithOptions

// Set sounds not to stop music
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];

Must admit I didn't delve into the details, but it works...

Good luck!

Oded Ben Dov's solution does the job, but you might not want to change your session category. For example, if you want your audio to keep playing while the screen is locked, you need the Playback category.

In that case, you can apply this category override instead:

UInt32 mixWithOthers = YES;
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(mixWithOthers), &mixWithOthers);
