How to launch view controller from alarm notification action in iOS?

Question

In my app i am using alarm functionality. It working fine. When i click the right button it launches my app. But i want to launch View Controller which is not an rootViewController. I am tried in searching in Google and SO but i couldn't get any idea or example.

I am looking for any example to achieve this.?

Thanks for your help guys.

EDIT

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{     
// Add the view controller's view to the window and display.
[self.window addSubview:alarmViewController.view];
[self.window makeKeyAndVisible];

application.applicationIconBadgeNumber = 0;


// Handle launching from a notification
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
    NSLog(@"Recieved Notification %@",localNotif);

    window = [[UIApplication sharedApplication] keyWindow];
    UIViewController *rootViewController = [window rootViewController];
    [rootViewController presentModalViewController:receipeViewController animated:YES];         
}


// Override point for customization after application launch.
return YES;

}

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
// Handle the notificaton when the app is running
NSLog(@"Recieved Notification %@",notif);   
//Called here as well
window = [[UIApplication sharedApplication] keyWindow];
    UIViewController *rootViewController = [window rootViewController];
    [rootViewController presentModalViewController:receipeViewController animated:YES];   
}

Finally Here's how I did it.

In didFinishLaunchingWithOptions:

//save the root view controller
[[self window] makeKeyAndVisible];
UINavigationController *navigationController = (UINavigationController*) self.window.rootViewController;
rootController = [[navigationController viewControllers] objectAtIndex:0];

Somewhere else in the app delegate:

[rootController performSegueWithIdentifier:@"destinationSegue" sender:self];

Then, in the storyboard, create a segue from the view that gets assigned to "rootController" to the desired optional view, and give that new segue the id destinationSegue. It takes some debugging to make sure the rootController variable gets assigned to the correct view.
