Im using Navigation Controller for my ViewControllers,I set my importantViewController as something like this to be its RootView:

UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController: vc];
[self presentModalViewController: navControl animated: YES];

Then, I pushView anotherView the FrontViewController like this:

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

After a button is pressed in FrontViewController another view will be pushed ViewA but it is connected with another ViewController ViewB the same way as this AGAIN:

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

(Which I think Im doing wrong when dismissing either of them with [self.navigationController popViewControllerAnimated:YES];)

This is an illustration:

My problem is, I need to navigate between View A and View B then when I dismiss either of them it will got back to FrontViewController. Like a child of a child View. Thanks.
