Can a UIViewController add itself to a UINavigationController

I'm starting an app where I'd like to have multiple view controllers. Some of the views will be displayed inside of a navigation controller. I can create a navigation controller and then add another instantiated view controller to it. But what I'd like to do, is just instantiate a view controller that has its own view and is the root view controller of a navigation view controller. So when I instantiate the view controller, I'd like for it create a navigation controller and push "self" on to it. When I do it my simulator crashes and the details don't really give a reason. The console does not display anything. Any ideas. My reason for this is to separate out logic without have a view controller that simply creates a navigation controller and then pushes another view controller on it as the root view controller.

I'm not entirely sure if I understand your question correctly. Why would it be preferable if the view controller pushed itself to the navigation controller? I mean, you have to instantiate your view controller at some point in code (either app delegate or another view controller) anyway. Why can't you just create the navigation controller there, instantiate your VC and then push it onto the nav controller? As far as I can see, this doesn't involve creating any additional view controllers.

Anyway, having a view controller decide by itself where it is used (ie. pushed onto), is not best practice. This way you lose the flexibility of using it in other contexts. Always try to couple your components as loosely as possible.
