class TabbarControllerVC: UITabBarController, UITabBarControllerDelegate{



    let homeVC = HomeVC(nibName: "HomeVC", bundle: nil)

    let listVC = HomeVC(nibName: "HomeVC", bundle: nil)

    let notificationVC = HomeVC(nibName: "HomeVC", bundle: nil)

    let settingVC = MyProfileVC(nibName: "MyProfileVC", bundle: nil)



    override func viewDidLoad() {

        super.viewDidLoad()

        self.delegate = self



        tabBar.tintColor = ColorConstants.ThemeColor



        var tabbarControllers = [UIViewController]()

        tabbarControllers.append(homeVC)

        tabbarControllers.append(listVC)

        tabbarControllers.append(notificationVC)

        tabbarControllers.append(settingVC)



        self.setViewControllers(tabbarControllers, animated: true)



        homeVC.tabBarItem = UITabBarItem(title: "", image: UIImage(named : "Home"), selectedImage: UIImage(named : "Home"))

        listVC.tabBarItem = UITabBarItem(title: "", image: UIImage(named : "List"), selectedImage: UIImage(named : "List"))

        notificationVC.tabBarItem = UITabBarItem(title: "", image: UIImage(named : "Notification"), selectedImage: UIImage(named : "Notification"))

        settingVC.tabBarItem = UITabBarItem(title: "", image: UIImage(named : "Setting"), selectedImage: UIImage(named : "Setting"))



        UITabBar.appearance().tintColor = ColorConstants.ThemeColor



        homeVC.tabBarItem.imageInsets = UIEdgeInsets(top: 4, left: 0, bottom: -4, right: 0)

        listVC.tabBarItem.imageInsets = UIEdgeInsets(top: 4, left: 0, bottom: -4, right: 0)

        notificationVC.tabBarItem.imageInsets = UIEdgeInsets(top: 4, left: 0, bottom: -4, right: 0)

        settingVC.tabBarItem.imageInsets = UIEdgeInsets(top: 4, left: 0, bottom: -4, right: 0)



        if #available(iOS 10.0, *) {

            UITabBar.appearance().unselectedItemTintColor = ColorConstants.BlackColor

        } else {

        UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: ColorConstants.BlackColor], for: .normal)



        }

    }



    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }



    func setupTabBarSeparators() {

        let itemWidth = floor(self.tabBar.frame.size.width / CGFloat(self.tabBar.items!.count))



        // this is the separator width.  0.5px matches the line at the top of the tab bar

        let separatorWidth: CGFloat = 0.5



        // iterate through the items in the Tab Bar, except the last one

        for i in 0...(self.tabBar.items!.count - 1) {

            // make a new separator at the end of each tab bar item

            let separator = UIView(frame: CGRect(x: itemWidth * CGFloat(i + 1) - CGFloat(separatorWidth / 2) , y: 15, width: CGFloat(separatorWidth), height: self.tabBar.frame.size.height - 30))



            // set the color to light gray (default line color for tab bar)

            separator.backgroundColor = UIColor.lightGray



            self.tabBar.addSubview(separator)

        }

    }



    override func viewWillAppear(_ animated : Bool){

        super.viewWillAppear(true)

        setupTabBarSeparators()

    }
