在iOS Swift中从侧栏菜单导航时，标签栏隐藏吗？

Question

SWRevealviewcontroller用于侧栏菜单。菜单包含主页，个人资料，注销等。点击主页单元格时，将其推送到主页视图控制器，但选项卡栏消失。

这是菜单视图控制器中侧边栏菜单导航的代码：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{


    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! MenuTableViewCell

    cell.menuName.text = menuName[indexPath.row]
    cell.menuIcon.image = UIImage(named: menuImage[indexPath.row])


    return cell

}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

  //        tableView.deselectRow(at: indexPath, animated: true)

    let row = indexPath.row

    if row == 0{

        let storyboard = UIStoryboard(name: "Home", bundle: nil)

        let obj = storyboard.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
        let navController = UINavigationController(rootViewController: obj)
        navController.setViewControllers([obj], animated:true)
        tabBarController?.tabBar.isHidden = false
        self.revealViewController().setFront(navController, animated: true)
        self.revealViewController().setFrontViewPosition(FrontViewPosition.left, animated: true)
    //            self.revealViewController().tabBarController?.tabBar.isHidden = false



    } else if row == 1{

        let storyboard = UIStoryboard(name: "Bookings", bundle: nil)
        let obj = storyboard.instantiateViewController(withIdentifier: "BookingsViewController") as! BookingsViewController
        let navController = UINavigationController(rootViewController: obj)

        navController.setViewControllers([obj], animated:true)
        self.revealViewController().setFront(navController, animated: true)
        self.revealViewController().setFrontViewPosition(FrontViewPosition.left, animated: true)


    } else if row == 2 {

        let storyboard = UIStoryboard(name: "Profile", bundle: nil)
        let obj = storyboard.instantiateViewController(withIdentifier: "profileViewController") as! profileViewController
        let navController = UINavigationController(rootViewController: obj)
        navController.setViewControllers([obj], animated:true)
        self.revealViewController().setFront(navController, animated: true)
        self.revealViewController().setFrontViewPosition(FrontViewPosition.left, animated: true)

    } else if row == 3 {
        print(indexPath)
        // Log out user from Firebase
        AuthService.signOut(onSuccess: {
            // Present the Sign In VC
   //                PrefsManager.sharedinstance.logoutprefences()
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let signInVC = storyboard.instantiateViewController(withIdentifier: "signInViewController")
                        self.present(signInVC, animated: true)

   //                self.navigationController?.pushViewController(signInVC, animated: true)

        }) { (errorMessage) in

            ProgressHUD.showError(errorMessage)

        }



    }


}

在主视图控制器中：

        //Hamberg menu - revel view controller
    if self.revealViewController() != nil {
        menuBtn.target = self.revealViewController()
        menuBtn.action = #selector(SWRevealViewController.revealToggle(_:))
        self.revealViewController().panGestureRecognizer().isEnabled = true

    }

鉴于self.tabBarController？.tabBar.isHidden = false在viewdidload，viewdidappear，viewwillappear中出现，但它不起作用。
