Mi aplicación reproduce mp4 con AVPlayer, cuando mi aplicación termina de iniciarse, interrumpe la música del iPod, aunque he configurado la sesión de audio para permitir la mezcla con otras personas en

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    AudioSessionInitialize(NULL, NULL, NULL, NULL);
    AudioSessionSetActive(true);
    UInt32 sessionCategory = kAudioSessionCategory_AmbientSound;
    AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
    UInt32 allowMixWithOthers = true;
    AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(allowMixWithOthers), &allowMixWithOthers);

Después de que apareciera el controlador de vista, reinicio la música del iPod, funciona bien con mi aplicación sin interrupción y la aplicación no interrumpirá más la música.

¿Alguien sabe si el problema puede resolverse o no? También revisé elmyapp-info.plist, no encuentra propiedades para evitar interrumpir el iPod.

Todos los métodos de AudioSession no devuelven ningún error.

Aquí están los registros en iPhoneConfigureUtility:

El siguiente es mi programa de prueba:

OSStatus status = AudioSessionInitialize(NULL, NULL, NULL, NULL);
status = AudioSessionSetActive(true);
UInt32 sessionCategory = kAudioSessionCategory_AmbientSound;
status = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
UInt32 allowMixWithOthers = true;
status = AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(allowMixWithOthers), &allowMixWithOthers);

[self.window addSubview:playerView];
[playerView release];

self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
