Question

I’ve got a hierarchy of 3 ViewControllers on a UINavigationController app.

Start in VC1, from there you can load VC2. In VC2 you can load VC3.

You can navigate backwards through the VC’s by pressing the left nav button on the navbar.

But the designer wants to be able to jump from VC1->VC3, and then if you press the left navbar button to go back it will take you to vc2.

Is it possible to have have this kind of navigation with a NAV controller?

If the user wants to go VC1-VC3 can i push both VC2 and then VC3 onto the navigationController stack so that the navigation is maintained correctly.

Also if the user wants to go from VC3->VC1 can i pop both VC3 and then VC2 off the navigationController stack so that VC1 displays?

Answer 1

Push BOTH VC2 and VC3 onto the stack to preserve the navigation when pressing the back button. To go from VC3 to VC1 you can use…

[navigationController popToViewController:vc1 animated:YES];

or if VC1 is the root…

[navigationController popToRootViewControllerAnimated:YES];
