Changing supported interface orientations programmatically in the View controller .m file problem

Question

I am currently working on a video based application, in the info.plist file I have all orientations supported and in the AppDelegate.m file I have UIInterfaceOrientationPortrait and UIInterfaceOrientationPortraitUpsideDown supported. However the supported Orientations of the AppDelegate only work at the main screen (I am using a Navigation Controller so I think that is what is causing that issue). In one of my ViewControllers (not the main screen) I have a moviePlayer that plays fullscreen when a Table View Item is selected. In the .m file for the view controller the code I have for to play the video is the following (which works by the way):

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    //Working out of file path for selected video
    NSLog(@"didSelectRowAtIndexPath");
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];
    NSString *currentFileName = [filePathsArray[indexPath.row] lastPathComponent];
    NSString *documentsDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSString *filePath = [documentsDirectoryPath stringByAppendingPathComponent:currentFileName];
    NSURL *videoURL =[NSURL fileURLWithPath:filePath];


    //selectors set
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enteredFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(exitedFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];


    //Play the movie now
    self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
    self.moviePlayer.view.frame = self.view.frame;
    [self.view addSubview:moviePlayer.view];
    [self.moviePlayer setFullscreen:YES animated:YES];
    [self.moviePlayer play];

    //Deselect Tableview item
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

}

- (void)willEnterFullscreen:(NSNotification*)notification {
    NSLog(@"willEnterFullscreen");
}

- (void)enteredFullscreen:(NSNotification*)notification {
    NSLog(@"enteredFullscreen");
    AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
    appDelegate.fullScreenVideoIsPlaying = @"TRUE";
    NSLog(appDelegate.fullScreenVideoIsPlaying);
}

- (void)willExitFullscreen:(NSNotification*)notification {
    NSLog(@"willExitFullscreen");
    AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
    appDelegate.fullScreenVideoIsPlaying = @"FALSE";
    NSLog(appDelegate.fullScreenVideoIsPlaying);
}

- (void)exitedFullscreen:(NSNotification*)notification {
    NSLog(@"exitedFullscreen");
    [self.moviePlayer.view removeFromSuperview];
    self.moviePlayer = nil;
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (void)playbackFinished:(NSNotification*)notification {
    NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:
            NSLog(@"playbackFinished. Reason: Playback Ended");
            break;
        case MPMovieFinishReasonPlaybackError:
            NSLog(@"playbackFinished. Reason: Playback Error");
            break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
            break;
        default:
            break;
    }
    [self.moviePlayer setFullscreen:NO animated:YES];
}

The Current Orientation code in the Downloads.m file that does not work:

- (NSUInteger)supportedInterfaceOrientations
{
    AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];

    if([appDelegate.fullScreenVideoIsPlaying  isEqual: @"TRUE"]){

        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else{

        return UIInterfaceOrientationPortrait | UIInterfaceOrientationPortraitUpsideDown;

    }
}

- (BOOL)shouldAutorotate{
    return YES;


}

appDelegate.fullScreenVideoIsPlaying is declared as NSString in the AppDelegate.h. The reason for this was because I was having issues with it being a Boolean variable. So whenever a video is playing fullscreen it is == "TRUE" and when fullscreen is exited it is == "FALSE"

The if statements I have in the supportedInterfaceOrientations method are never being used and I have tested this by adding NSLog in it and searching for a output, which where never outputted in the debug area. So how do I change the supported interface orientations when the video plays full screen and reset them back to Portrait when fullscreen is exited. Is there another method I should be using? Any help will appreciated this problem is driving me mad.
