How to push viewcontroller from appdelegate in storyboard inside navigation controller

Question

I am using SWRevealViewController in my project, and I want to open a particular controller when the app receives a notification. I have tried so many solutions but nothing works.

I follow this http://www.appcoda.com/ios-programming-sidebar-navigation-menu/ by using storyboard. My storyboard is designed as below:

When the application receives a notification I want to load Photo view controller within its navigation controller. I tried with the following code in the AppDelegate:

UIStoryboard *st = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    photoViewController *descController = (PhotoViewController*)[st instantiateViewControllerWithIdentifier: @"photoView"];
    UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:descController];
    SidebarTableViewController *rearViewController = (SidebarTableViewController*)[st instantiateViewControllerWithIdentifier: @"menuController"];

    SWRevealViewController *mainRevealController = [[SWRevealViewController alloc]  init];

    mainRevealController.rearViewController = rearViewController;
    mainRevealController.frontViewController= frontNavigationController;
    self.window.rootViewController =nil;
    self.window.rootViewController = mainRevealController;
    [self.window makeKeyAndVisible];

This works, but creates a new Navigtion controller, and what I need is to use the one already defined in the storyboard, since it has specific properties.

Any idea?

Thanks

actually SwLRevalViewController Taken the ownership of Root, so do like this

in Appdelegate.m

//initially navigate to your Main controller on SWL

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler
{

   NSString *alert = userInfo[@"aps"][@"redirect_url"];
[[NSUserDefaults standardUserDefaults]setObject:alert forKey:@"itemType"];
 [[NSUserDefaults standardUserDefaults]synchronize];
 UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
SWRevealViewController *main = (SWRevealViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:@"SWRevealViewController"];

    self.window.rootViewController = main;
 }

//it automatically redirect to your root controller

on that main view controller ViewDidLoad check / Navigate to your photo view controller

        NSString *getType=[[NSUserDefaults standardUserDefaults]objectForKey:@"itemType"];
 if ([gettypeofItem isEqualToString:@"something"])
        {
   yourPhotoViewController *ivc=[self.storyboard instantiateViewControllerWithIdentifier:@"yourPhotoViewController"];

   [self.navigationController pushViewController:ivc animated:YES];
    }
  else

  {

   // do nothing 

  }

You can use following method

NSString *storyBoardName=@"Main_iPad";
if (isPhone)
    storyBoardName=@"Main_iPhone";
UIStoryboard *storyBoard=[UIStoryboard storyboardWithName:storyBoardName bundle:nil];

PlayVideoBySocketsScene *controller=[storyBoard instantiateViewControllerWithIdentifier:@"playVideoUsingSockets"];


float disptachTime=2.0;
if (value)
{
    disptachTime=1.0;
}
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(disptachTime * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    [[[[UIApplication sharedApplication] keyWindow] rootViewController]  presentViewController:controller animated:YES completion:nil];
