Push a ViewController from a Cocos2d scene - ios

Question

I am loading a cocos2d game inside an Storyboard. I implemented a CocosViewController that loads the cocos2d scene (IntroLayer) and IntroLayer that starts the game. I would like to go back to CocosViewController or open a new viewcontroller when the timer (countdown) is zero in the game.
I tried calling [[CCDirector sharedDirector] popScene]; when the countdown arrives to zero and with CocosViewController *cocos = [[CocosViewController alloc] init]; [cocos.navigationController dismissViewControllerAnimated:YES completion:nil];
in onExit method but the app crashes when the countdown arrives to zero, any suggestion?
My CocosViewController set up cocos2d
-(void)setupCocos2d {
CCDirector *director = [CCDirector sharedDirector];
//[[[self navigationController] navigationBar] setHidden:YES];
if([director isViewLoaded] == NO)
{
// Create the OpenGL view that Cocos2D will render to.
CCGLView *glView = [CCGLView viewWithFrame:self.view.bounds
pixelFormat:kEAGLColorFormatRGB565
depthFormat:0
preserveBackbuffer:NO
sharegroup:nil
multiSampling:NO
numberOfSamples:0];
// Assign the view to the director.
director.view = glView;
// Initialize other director settings.
[director setAnimationInterval:1.0f/60.0f];
[director enableRetinaDisplay:YES];
}
// Set the view controller as the director's delegate, so we can respond to certain events.
director.delegate = self;
// Add the director as a child view controller of this view controller.
[self addChildViewController:director];
// Add the director's OpenGL view as a subview so we can see it.
[self.view addSubview:director.view];
[self.view sendSubviewToBack:director.view];
// Finish up our view controller containment responsibilities.
[director didMoveToParentViewController:self];
// Run whatever scene we'd like to run here.
NSArray *parameters = [[NSArray alloc] initWithObjects:#"3", #"sound", #"countdown", nil];
if(director.runningScene)
[director replaceScene:[IntroLayer scene];
else
[director pushScene:[IntroLayer scene];
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(#"cocos2d controller viewdidload");
[self setupCocos2d];
}
-(void)viewDidUnload {
NSLog(#"did unload");
[[CCDirector sharedDirector] setDelegate:nil];
[[CCDirector sharedDirector] end];
}
IntroLayer creates the scene for the game. This is my onExit method:
-(void) onExit{
NSLog(#"Introscene exit");
[super onExit];
}
And this is the game. I want to load a viewcontroller when the game finished.
-(void)update:(ccTime)dt{
if (myTime > 0) {
myTime -= (float)dt;
[timeLabel setString:[NSString stringWithFormat:#"%.2f", myTime]];
} else {
myTime = 0;
[timeLabel setString:[NSString stringWithFormat:#"0.00"]];
[[CCDirector sharedDirector] popScene];
}
if (clicks < currentClicks) {
clicks = currentClicks;
//[clicksLabel setString:[NSString stringWithFormat:#"%i", clicks]];
}
}
-(void) onExit
{
[super onExit];
[[CCDirector sharedDirector] stopAnimation];
CocosViewController *cocos = [[CocosViewController alloc] init];
[cocos.navigationController dismissViewControllerAnimated:YES completion:nil];
// [cocos.navigationController popViewControllerAnimated:YES];
//AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
//[app.navController popViewControllerAnimated:YES];
//dismissModalViewControllerAnimated:YES
NSLog(#"game exit");
}

For pop IntroLayer To ViewConrtroller As below code
[[[CCDirector sharedDirector] navigationController] popViewControllerAnimated:YES];
