How to dismiss multiple ViewController instead of initial ViewController

I have this case

In the ViewControllerD, when the login section is expired, I will move back to LoginViewController so I want to dismiss all ViewControlelr instead of LoginViewController?

Any idea to do that? Any help or suggestion would be great appreciated

I have tried like that: When I dismiss the ViewControllerD successful, I send a block to ViewControllerC then I continue dismiss the ViewControllerC. After that I will dismiss the NavigationControllerB, but NavigationControllerB have many ViewController so I need to write many block code so I don't think it's a good idea

You can do something like,

 [[[[[self parentViewController]parentViewController] parentViewController]parentViewController] dismissViewControllerAnimated:YES completion:^{

   // perform task after completion
}];

Make sure that number of parent viewcontroller. this is example dissmiss paraentview controller according to your scenario.

Update :

try something like this,

 [self dismissViewControllerAnimated:YES completion:^{

    [[[[[self parentViewController]parentViewController] parentViewController]parentViewController] dismissViewControllerAnimated:YES completion:^{

        // perform task after completion
    }];

}];

Update 2 :

    [[[[[self parentViewController]parentViewController] parentViewController]parentViewController] dismissViewControllerAnimated:YES completion:^{

    [self dismissViewControllerAnimated:YES completion:nil];
}];

can do something like this, dismiss all parent vc and then dismiss current vc Hope this will help :)

If LoginViewController is your initialViewController, you can use this code :

//dismiss all presented view controllers if any
            UIViewController *vc = self.presentingViewController;
            while (vc.presentingViewController) {
                vc = vc.presentingViewController;
            }
            [vc dismissViewControllerAnimated:YES completion:NULL];
