i'm using mpmovieplayer to play audio stream, one problem i'm having trouble with handling intruptions e.g when call is received. My player is declared in viewcontroller and i beleive i need to do something in applicationdidresignactive in my appdelegate right? how do i do that if my appdelegate isn't aware of my moviePlayer? i'm new to iphone dev so i'm learning as i go and enjoying it :)

here is what i'm doing in viewcontroller

    -(IBAction)play1MButton:(id)sender{

    [[NSNotificationCenter defaultCenter] addObserver:self 
                selector:@selector(moviePlayerStatus:) 
                name:MPMoviePlayerPlaybackStateDidChangeNotification 
                object:nil];

    NSString *url = @"http://22.22.22.22:8000/listen.pls";

    [self.activityIndicator startAnimating];

    moviePlayer = [[MPMoviePlayerController alloc]
                                initWithContentURL:[NSURL URLWithString:url]];

   [moviePlayer prepareToPlay];

    [[NSNotificationCenter defaultCenter] addObserver:self 
                                  selector:@selector(moviePlayerLoadStateChanged:) 
                                  name:MPMoviePlayerLoadStateDidChangeNotification 
                                  object:nil];
    }
}

    -(void) moviePlayerStatus:(NSNotification*)notification {
    //MPMoviePlayerController *moviePlayer = notification.object;
    MPMoviePlaybackState playbackState = moviePlayer.playbackState;


    if(playbackState == MPMoviePlaybackStateStopped) {
        NSLog(@"MPMoviePlaybackStateStopped");
    } else if(playbackState == MPMoviePlaybackStatePlaying) {
        NSLog(@"MPMoviePlaybackStatePlaying");
    } else if(playbackState == MPMoviePlaybackStatePaused) {
        NSLog(@"MPMoviePlaybackStatePaused");
    } else if(playbackState == MPMoviePlaybackStateInterrupted) {
        NSLog(@"MPMoviePlaybackStateInterrupted");
    } else if(playbackState == MPMoviePlaybackStateSeekingForward) {
        NSLog(@"MPMoviePlaybackStateSeekingForward");
    } else if(playbackState == MPMoviePlaybackStateSeekingBackward) {
        NSLog(@"MPMoviePlaybackStateSeekingBackward");
    }
}

- (void) moviePlayerLoadStateChanged:(NSNotification*)notification {
    if ([moviePlayer loadState] != MPMovieLoadStateUnknown)
    {
        [[NSNotificationCenter  defaultCenter] removeObserver:self 
                        name:MPMoviePlayerLoadStateDidChangeNotification 
                           object:moviePlayer];

        [moviePlayer play];

        [self.activityIndicator stopAnimating]; 
        [moviePlayer setFullscreen:NO animated:NO];
    }

}

and in appdelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    // Override point for customization after application launch.
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];


    AVAudioSession *audioSession = [AVAudioSession sharedInstance];

    NSError *setCategoryError = nil;
    [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];
    if (setCategoryError) {

    }

    NSError *activationError = nil;
    [audioSession setActive:YES error:&activationError];
    if (activationError) { 
    }

I can catch the errors but how do i use the player from appdelegate?!!

thanks in advance
