Go back to unvisited page on IOS

Question

I am unfamiliar with IOS development, so probably a simple question: is it possible that the user presses the "back" button on the top, and go to a (so far) non-visited page? Here is the picture:

On window "1" user presses a button, the next window is "2". But here, if user presses the "back" button, go to page "3" (which was never opened so far)?

Thanks

You can simply redefine the back button by creating a new one in your second view controller like this :

- (void)viewDidLoad {
    [super viewDidLoad];

    UIButton *backButton = [[UIButton alloc] initWithFrame: CGRectMake(0, 0, 60.0f, 30.0f)];
    [backButton setTitle:@"Back" forState:UIControlStateNormal];
    [backButton setTitleColor:self.view.tintColor forState:UIControlStateNormal];
    [backButton addTarget:self action:@selector(pushToNextController) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *backButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
    self.navigationItem.leftBarButtonItem = backButtonItem;
}

- (void)pushToNextController {
    UIViewController *thirdViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"thirdViewController"];
    [self.navigationController pushViewController:thirdViewController animated:YES];
}
