Programmatically Get Navigation Controller from Editor > Embed In > Navigation Controller

I used a "push" segue from a ViewController after using the menu in XCode Editor > Embed In > Navigation Controller. I have a button on this presented view that slides in from the side that I would like to dismiss the pushed view. I realize there is a method:

[self.navigationController popViewControllerAnimated:YES];

But I don't have a pointer to the Navigation Controller I added through the XCode menu..

My App Delegate has the window's root view controller as my main ViewController - so I haven't done anything there after adding the Navigation Controller from the XCode menu.

How can I get a pointer to this added Navigation Controller so I can call the pop method programmatically on the pushed view controller? Thanks!

That is the correct function to use, and will automatically return the navigation controller that you "pushed" into.

From the UIViewController class reference:

navigationController
The nearest ancestor in the view controller hierarchy that is a navigation controller. (read-only)

@property(nonatomic, readonly, retain) UINavigationController *navigationController

Discussion
If the receiver or one of its ancestors is a child of a navigation controller, this property contains the owning navigation controller. This property is nil if the view controller is not embedded inside a navigation controller.
