Pushing view controller from AppDelegate - ios

Question

I am just beginning to learn how to implement Push notifications with iOS and Parse.
At the moment, I can send push notifications from the Parse dashboard to the app,the notification is received, as I can see in the Xcode console, but now my issue is that I am not able to open a view controller from the AppDelegate.
This is my code:
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {
// Create empty photo object
NSString *photoId = [userInfo objectForKey:#"p"];
NSLog(#"P=%#",photoId);
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
Aceptado *targetViewController = (Aceptado*)[mainStoryboard instantiateViewControllerWithIdentifier:#"servicio_aceptado"];
UINavigationController *controlador = [[UINavigationController alloc]init];
[controlador pushViewController:targetViewController animated:YES];
}
As I said, the console show the log NSLog(#"P=%#",photoId) , the notification is received, but the view controller is not shown, any warning or error is shown.
Any help is welcome.

I have solved my problem like this:
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main"
bundle: nil];
Aceptado *controller = (Aceptado*)[mainStoryboard
instantiateViewControllerWithIdentifier: #"servicio_aceptado"];
controller.id_not =_id_not;
controller.idemployee = _idemployee;
controller.fullname = _fullname;
controller.phone = _phone;
controller.photo = _photo;
controller.dni = _dni;
controller.licenseplate = _licenseplate;
controller.model = _model;
controller.color = _color;
controller.latitude = _latitude;
controller.longitude = _longitude;
self.window.rootViewController = controller;
Now I can pass values to the target view controller from the AppDelegate file, keeping the SWRevealViewController structure.
Thank to all of you for your proposals.

try this code.
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
Aceptado *targetViewController = (Aceptado*)[mainStoryboard instantiateViewControllerWithIdentifier:#"servicio_aceptado"];
UINavigationController *navVc=(UINavigationController *) self.window.rootViewController;
[navVc pushViewController: targetViewController animated:YES];
may help you.

Try this once.
UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
Slider1ViewController *viewcontroller = [storyBoard instantiateViewControllerWithIdentifier:#"Slider1ViewController"];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
[navController setViewControllers: #[viewcontroller] animated: YES];
[self.revealViewController setFrontViewController:navController];
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];

You should not create new NavigationController, but use one existing. Usually it is rootViewController property of your key window.
Try this:
UINavigationController *controlador = self.window.rootViewController;
If you want to display your targetViewController in SWRevealViewController you may change your code as this:
SWRevealViewController *controlador = (SWRevealViewController)self.window.rootViewController;
[controloador pushFrontViewController:targetViewController animated:YES];
If you need display targetViewController over SWRevealViewController, use this:
WRevealViewController *controlador = (SWRevealViewController)self.window.rootViewController;
[controloador presentViewController:targetViewController
animated:YES
completion:nil];
If you need just replace SWRevealViewController with targetViewController use this:
self.window.rootviewController=targetViewController;
But don't forget save your SWRevealViewController in some another property.

Try this:
SomePageViewController *someVC = [self.storyboard instantiateViewControllerWithIdentifier:#"SomeVC"];
self.navController = [[UINavigationController alloc] initWithRootViewController:someVC];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];

If you want to push a view controller into navigation stack from appDelegate you need to cast your rootView controller as UINavigation Controller
