UINavigationController initWithRootVC: how to force the VC to load?

I created a view controller and then create a navigation controller with:

initWithRootViewController:

then I observed that it calls pushViewController:animated:, since I am using my own UINavigationController subclass, I overwrite pushViewController:animated::

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [super pushViewController:viewController animated:animated];
    // do something with the VC
}

The problem is, immediately after

[super pushViewController:viewController animated:animated];

the viewController.isViewLoaded is NO, so I cannot actually do what I want, is there a way to force a VC to be loaded, when it is used as the root VC of a navigation controller?

Thanks!

edit, below is the code:

MyViewController *vc = [[MyViewController alloc] initWithNib:@"" bundle:nil];
MyNavController *nav = [[MyNavController alloc] initWithRootViewController:vc];

self.revealViewController.frontViewController = nav;

Access view before pushing viewController.

[viewController view];//this will load your view
[super pushViewController:viewController animated:animated];

I found this answer in the Apple documentation

The UINavigationController class implements a specialized view controller that manages the navigation of hierarchical content. This class is not intended for subclassing.
