So I wanted to push a view into the navigation stack while simultaneously popping to that view (so that view slide animation goes backwards!). This was my solution. Just assumes your last navigation area is your current view and the second to last is replaced with the new view. You can easily add instead of replacing.

navigationPushPop.m

NSMutableArray* newViewControllers = [self.navigationController.viewControllers mutableCopy];
[newViewControllers replaceObjectAtIndex:[newViewControllers indexOfObject:self] withObject:loginController];
[self.navigationController setViewControllers:newViewControllers animated:YES];
