Dismissing a ViewController shown as Popover segue from within another Popover

问题

My storyboard is using a UINavigationController(VC0), I segue using a UIPopover to load a new UIViewController (VC1). From this new UIViewController, I am popping to a new UIViewController (VC2). When I attempt to close this newest popover, I am being quit back to the UINavigationController.

The code that I'm using in VC0 to show the VC1 as popover, VC1 to VC2 is the same code (different identifier though):

[self performSegueWithIdentifier:@"titlePopover" sender:self];

The code that I'm using in VC2 to dismiss the popover is:

UIViewController *vc = [self presentingViewController];
[self dismissViewControllerAnimated:YES completion:^{
    [[vc presentingViewController] dismissViewControllerAnimated:YES completion:nil];
}];

What it does is dismisses VC2, shows VC1 for a split second, then dismisses VC1 and goes back to the VC0. I want to be able to dismiss VC2 only, so that I'm on VC1

If you performing sugue modally, use code navigate back:

[self dismissViewControllerAnimated:YES completion:nil];

If performing push segue, use code to navigate back:

[self.navigationController popViewControllerAnimated:YES];
