How to display/hide the navigation bar and status bar separately on iPhoneX

I would like to control the display/hide of NavigationBar and StatusBar in one iOS application.

iPhone6, iPhone7 and iPhone8 display as intended.
The status bar and navigation bar are not displayed on the first screen.
On the next screen, the status bar remains hidden and the navigation bar appears.

However, on iPhoneX, NavigationBar will also be displayed.

prefersStatusBarHidden in ViewController is set to YES.

Also, the height of NavigationBar will be similar to that of StatusBar.

If you know the solution, please let me know.

I look forward to your kind cooperation.

The code looks like the following.

FirstViewController.m

 - (void) viewDidLoad
{
    superviewDidLoad;

    self.view.backgroundColor=UIColor.yellowColor;

    self.navigationController.navigationBarHidden=YES;
}                                 }

- (void) viewWillAppear: (BOOL) animated
{
    super viewWillAppear: animated;

    self.navigationController.navigationBarHidden=YES;
}

- (void) touchUpButton: (UIButton*) button
                                  {
    SecondViewController* vc = [[SecondViewController alloc] init];
    [self.navigationController pushViewController:vcanimated:YES];
}

- (BOOL) preferStatusBarHidden
{
    return YES;
}

SecondViewController.m

 - (void) viewDidLoad
{
    superviewDidLoad;

    self.navigationController.navigationBarHidden = NO;
    self.navigationItem.title=@"SecondView";

    self.view.backgroundColor=UIColor.cyanColor;
}

- (void) viewWillAppear: (BOOL) animated
{
    self.navigationController.navigationBarHidden = NO;
}

- (BOOL) preferStatusBarHidden
{
    return YES;
}

I also asked a question on StackOverFlow at my home (English version), but iPhoneX behavior, so it is not possible to display the navigation bar and not display the status bar.

On iPhone X, Control Show/Hide NavigationBar and StatusBar separately
https://stackoverflow.com/questions/48207378/on-iphonex-control-show-hide-navigationbar-and-statusbar-separately

Also, I was aware of it, but Apple's UI guidelines suggest that iPhoneX should display the status bar.
