Question

I have a main navigation controller with a root view controller. In the root view controller, on the push of a button I present second view controller like this:

SecondVC *secondVC = [[SecondVC alloc] initWithNibName:@"SecondVC" bundle:nil];
[self.navigationController presentModalViewController:secondVC animated:YES];

In the second view controller, on the push of an other button, I want to present a third view controller (this time from a Storyboard):

ThirdVC *thirdVC = [[UIStoryboard storyboardWithName:@"Settings" bundle:nil] instantiateInitialViewController];
[self.navigationController presentModalViewController:thirdVC animated:YES];

However this doesn’t do anything. I debugged and it turned out, that self.navigationController is nil.

Shouldn’t it be the main navigation controller? Or doesn’t presentModalViewController: add the view controller to the stack? Do I always have to put a view controller in a navigation controller before presenting id modally?

Answer 1

The new view controller SecondVC is being presented modally, and it’s not added to the view controller stack of the navigationController. You need to create a new UINavigationController, and put SecondVC inside the navController before presenting it modally.
