Question

After my rootViewController, there is a workflow that would go like this

viewController1 -> push viewController2 -> push viewController3 -> ***** viewController2

I would like to popToViewController3. However, I need to go to viewController1 first because viewController1 basically determines which instance of viewController2 to push. So I

// pseudo code
[popToViewController:vc1 animated:NO];
[self.navigationController pushViewController2 animated:YES];

I basically pop before pushing so I don’t end up getting vc2, vc3, vc2, vc3, vc2 etc. But in doing this, since it animates the push of the last viewController, it gives the user the impression that a new viewController was pushed onto the stack, vs popping to the previous viewController. Is there a way to get around this ? If I animate the pop and not the last push, I do not get the correct viewController I want on top by the looks of it. Thanks.

You can retrieve (viewControllers), modify, and “reinstall” (setViewControllers) the list of view controllers managed by the navigation controller, and the “reinstall” can (in theory) be animated. (However, I had some problems with animation in practice, though I don’t recall the details.)
