Question

I am working on a navigation based application which involves LOGIN view.
My approach to deal with the same navigation hierarchy (which was taking back to the login page)was

• Use two navigation controllers

• as soon as the user logs in create a new navigation controller

  • assign the new view controller’s root to the post login view

    someViewController.navigationController = [[[UINavigationController alloc]initWithRootViewController:someViewController ] autorelease];
    

  • assign this navigation controller to the window:

    MYAppDelegate *appDelegate = (MYAppDelegate *)[[UIApplication sharedApplication] delegate]; 
    

    appDelegate.navigationController = someViewController.navigationController;

    UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [window  addSubview:someViewController.navigationController.view];
    [window  makeKeyAndVisible];
    

-finally push the “someViewController” to stack.

    [self.navigationController pushViewController:someViewController animated:YES];

ALL WORKING FINE TILL NOW..

outcomes:

1. the someViewController’s navigation controller is the new navigationController for the complete app and there is no way to go back to LOGIN view.

2. I am able to push new ViewControllers to the stack and navigate to and fro upto next level.

PROBLEM :!!

“I am only able to push new ViewControllers to the stack and navigate to and fro. up to the next level and not further…”

say:

(newroot)master–>subordinates–X->details. // i am not able to navigate to 3rd level.
(newRoot)subordinate–>details.

what else I have tried before posting?

1. tried simply setting the root of the same navigationController to the POST-LOGIN ViewControlller
   
   issue: it din’t worked either.

please guide
Thank you in anticipation.

Answer 1

Try the following way, take a navigationController in appDelegate say navController
In loginViewController, after you login success,

HomeViewController *svc=[[HomeViewController alloc]initWithNibName:@"HomeViewController" bundle:nil];

            appdelegate.homeViewController=svc;

            appdelegate.navController.navigationBarHidden=YES;
            appdelegate.navController=[[UINavigationController alloc] initWithRootViewController:appdelegate.homeViewController];
            [appdelegate.window addSubview:appdelegate.navController.view];

            [svc release];

then you can remove login screen as [self.view removeFromSuperview]; if added as subView
