because i want to play music audioSessionCategory = AVAudioSessionCategoryPlayback
i have changed some code…
in CDAudioManager.m
// Init

  • sharedManager
    {
    @synchronized {
    if {
    if {
    //Set defaults here
    //configuredMode = kAMM_FxPlusMusicIfNoOtherAudio;
    configuredMode = kAMM_MediaPlayback; // I want to set audioSessionCategory
    }
    sharedManager = init:configuredMode];
    _sharedManagerState = kAMStateInitialised;//This is only really relevant when using asynchronous initialisation
    postNotificationName:kCDN_AudioManagerInitialised object:nil];
    }
    }
    return sharedManager;
    }

if i changed that code,

UIApplicationState has 3 types
UIApplicationStateActive - Foreground
UIApplicationStateInactive - Power button
UIApplicationStateBackground - Home button

then, if UIApplication was called ‘applicationWillEnterForeground’
check the UIApplicationState,
if it was UIApplicationStateInactive, call performSelector

follow AppController.mm

  • (void)applicationWillEnterForeground:(UIApplication )application {
    /
    Called as part of transition from the background to the inactive state: here you can undo many of the changes made on entering the background.
    */

if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive ) {
[self performSelector:@selector(CallCocosEnterForeground) withObject:nil afterDelay:.1f];
}else {
[self CallCocosEnterForeground];
}
}

  • (void)CallCocosEnterForeground {
    cocos2d::CCApplication::sharedApplication()->applicationWillEnterForeground();
    }
