To move back to HomeViewController

If you use pushViewController to show current view controller. You have to use popViewControllerAnimated instead of pushViewController. Try replace your popVC with my code below.

- (void) popVC{
    [self.navigationController popViewControllerAnimated:YES];
}

If you use presentViewController to show current view controller. You have to use dismissViewControllerAnimated instead of pushViewController. Try replace your popVC with my code below.

- (void) popVC{
    [self dismissViewControllerAnimated:YES completion:nil];
}

Try this:
By Writing the First Line you get the Indexes of all View Controllers and from second Line You will reach up to your Destination.

NSArray *array = [self.navigationController viewControllers];

[self.navigationController popToViewController:[array objectAtIndex:2] animated:YES];
