There is a property of UINavigationController namely "viewControllers" which will work as follows:

NSArray *controllers = [navController viewControllers];

And now you can access any view controller from the returned array!

By accessing the viewControllers property of UINavigationController you will get an array of pushed viewControllers So now you can access any viewController by indexing array.
