copied!<p><strong>EDIT</strong></p> <p>Thanks for posting your code. So, to address your final question first, I don't recommend controlling your navigation stack from the app delegate. You should be controlling the stack from the view controllers that are the children of the navigation controller.</p> <p>To that point, remember the hierarchy of view controllers: <code>UINavigationController</code> inherits from <code>UIViewController</code>, and <code>UIViewController</code> has properties defined for all the things you'd see in a navigation layout such navigation items and title. More importantly, it also has properties for its parent view controllers, the view controller that presented it, and its navigation controller. So, considering the hierarchy, your app delegate should only instantiate the navigation controller's root VC and the nav controller itself, and then subsequently set the nav controller's root VC.</p> <p>From there, you should be pushing and popping other VCs from the VCs themselves. Remember, every VC has a property that's automatically set to point at the navigation controller it's a part of. That's why <code>[self.navigationController pushViewController:]</code> works. For instance, if I have a nav controller whose root VC is a <code>UITableViewController</code>, and tapping on one of the items in the table view pushed a new VC onto the stack, I would push that VC from the table VC and not from the nav controller class or the app delegate.</p> <p>Sorry if that's confusing. Please let me know if that needs clarification and I'll give it my best. Otherwise, hopefully that gets you on the right track.</p>
