Question

In the didFinishLaunchingWithOptions of my application , the code is

   _homeViewController = [[HomeViewController alloc]init];
    UINavigationController*  _navigationController = [[UINavigationController alloc] initWithRootViewController:_homeViewController];
    [self.window setRootViewController:_navigationController];
    [_navigationController setNavigationBarHidden:YES];
    [self.window makeKeyAndVisible];

and in the HomeViewController , I am having two buttons, If the button is pressed , I am presenting the ViewController. If button1 is pressed , the code is

if (_detailsViewController == nil)
            _detailsViewController = [[DetailsViewController alloc]init];

       [self.navigationController presentModalViewController:_detailsViewController animated:YES];

Now when I am in the detailsViewController and I pressing the iPhone Home button, in the same class I am using the UIApplicationDidEnterBackgroundNotification and calling a method to execute the following line

[self.navigationController popToRootViewControllerAnimated:YES];

So I thought when I open the application again, I can see the HomeViewController, but it doesn’t work. Please help me !!

Answer 1

It seems the reason why I am not able to pop to the root view is , I am presenting the ViewController in between, If the ViewController comes along with the navigation controller, i.e , if the ViewController is pushed as a navigation controller then i can pop to the root view controller
