Question

I am developing a cocos2d game in ios.
This is the code for app delegate :

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.homeViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    self.window.rootViewController = self.homeViewController;
    [self.window makeKeyAndVisible];

In this I am making the ViewController class the rootViewController.
And I am presenting GameOptionsViewController class from HomeViewController class.
From GameOptionsViewController I am calling the method in app delegate to add the game scene.

-(void)addGameScene

    {

    CCDirector *director = [CCDirector sharedDirector];
    if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
        [CCDirector setDirectorType:kCCDirectorTypeMainLoop];
    else {
        [CCDirector setDirectorType:kCCDirectorTypeDisplayLink];
    }

    // Init the View Controller
    viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
    viewController.wantsFullScreenLayout = YES;
    if(!glView)
        glView = [[EAGLView alloc] initWithFrame:[window bounds]];
    [director setOpenGLView:glView];

    [director setOpenGLView:glView];
    [director setDeviceOrientation:kCCDeviceOrientationLandscapeLeft];
    [viewController setView:glView];
    [window setRootViewController:viewController];
    [window addSubview: viewController.view];
    [window makeKeyAndVisible];
    [[CCDirector sharedDirector] runWithScene: [HelloWorldLayer scene]];
}

Now when i want to hide the game scene, i use the code:

   [[CCDirector sharedDirector] stopAnimation];
   [[CCDirector sharedDirector].openGLView setHidden:YES];

The game scene is hidden, but the previous view, i.e GameOptionsViewController does not show up.
What I am doing wrong??.. Please advice..

Answer 1

here you set the RootViewController with viewController like that..

[window setRootViewController:viewController];

as it just set your GameOptionsViewController class object as a rootViewController..

For Ex.

   ViewController *homeViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
   window.rootViewController = homeViewController;

i hope this help you…
