How to access the stack in UINavigationController

Question

viewControllers

The view controllers currently on the navigation stack.

@property(nonatomic, copy) NSArray *          


        

Answer 1

UINavigationControllers have a property called viewControllers as you have stated above. Since this is an array of View Controllers, referencing a specific view controller in this hierarchy is no different than accessing any other object in an array.

UIViewController *theControllerYouWant = [self.navigationController.viewControllers objectAtIndex:(theIndexOfYourViewController)];

In addition check out the Navigation Controllers article in the iOS Developer Library, specifically the section called 'Modifying the Navigation Stack'.
