Backing up 2-4 previous views...

Question

I'm writing a standard table view application with a number of views in the hierarchy. When I've clicked in 3-4 views, is there a way to get back to the top view? I tried loading it, but then I lose the hierarchy.

I know this command will bring me back 1 view, which is what the 'back' button does:

[self.navigationController popViewControllerAnimated:YES];

You can use popToRootViewControllerAnimated: or popToViewController:animated: methods.

To get the viewcontroller to which you need to jump, get a list of all viewcontrollers from the navcontroller in an array and then select the viewcontroller from this array.

i.e. if your hierarchy is svc->svc2->vc1->vc2->vc3->vc4 and you want to go back to vc1 from vc4, do this

NSArray *viewControllers = [[self navigationController] viewControllers];
UIViewController *controller = [viewControllers objectAtIndex:2];
[[self navigationController] popToViewController:controller animated:YES];
