如何使用Xibs在Swift中使用标签栏进行导航

Question

我正在尝试使用选项卡来使用Xibs导航到其他视图控制器。但是，我找不到切实的资源来继续前进。我当前的解决方案涉及映射，但似乎看不出问题出在哪里。

import UIKit

class BottomNavViewController: UIViewController {

    @IBOutlet weak var home: UITabBarItem!
    @IBOutlet weak var assets: UITabBarItem!
    @IBOutlet weak var transactions: UITabBarItem!
    @IBOutlet weak var profile: UITabBarItem!
    @IBOutlet weak var tabBar: UITabBar!

    override func viewDidLoad() {
        super.viewDidLoad()

        navigateTab()
    }

    func navigateTab() -> Void{

        let tabBarController = UITabBarController()
        let homeVC = HomeViewController()
        let assetsVC = AssetsViewController()
        let transactionsVC = TransactionsViewController()
        let profileVC = ProfileViewController()

        let controllers = [homeVC, assetsVC, transactionsVC, profileVC]

        tabBarController.viewControllers = controllers.map {
            UINavigationController(rootViewController: $0)
        }
    }
}

简单地说就是这样，您想使用UITabbarController

class MYTabViewController: UITabBarController {


    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func viewWillAppear(_ animated: Bool) {
        let firstVC = FirstVC()
        firstVC.tabBarItem = UITabBarItem(title: "Tab 1", image:(your image), tag: 0)

        let secondVC = SecondVC()
        secondVC.tabBarItem = UITabBarItem(title: "Tab 2", image: (your image), tag: 1)

        viewControllers = [firstVC,secondVC]
    }

}
