UITabBar在iOS中不显示图标

在以编程方式登录后，我正在创建一个选项卡栏控制器。所以我使用下面的代码。我的问题是图标没有显示在选项卡栏中

func makeTabBarController() -> Void {
        
        
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc1 = storyboard.instantiateViewController(withIdentifier: "homevcID")
        
        
        let nav1 = UINavigationController()
        nav1.viewControllers = [vc1]
        nav1.tabBarItem = UITabBarItem(title: "Steps", image: UIImage(named: "music.png"), tag: 1)
        
        let vc2 = storyboard.instantiateViewController(withIdentifier: "historyvcID")
        
        let nav2 = UINavigationController()
        nav2.viewControllers = [vc2]
        nav2.tabBarItem = UITabBarItem(title: "History", image: UIImage(named: "music"), tag: 2)
        
        
        let tabBarVc = UITabBarController()
        //tabBarVc.tabBar.barTintColor = .green
        //tabBarVc.tabBar.tintColor = .white
        //tabBarVc.tabBar.unselectedItemTintColor = .systemGray
       // tabBarVc.tabBar.isTranslucent = true
        //
        
        tabBarVc.viewControllers = [vc1, vc2]
        
        window?.rootViewController = tabBarVc
        
    }

为导航控制器设置rootViewController，如下所示：

let nav = UINavigationController(rootViewController: vc)

您可以尝试以下方法：

let nav1 = UINavigationController(rootViewController: vc1)
nav1.tabBarItem = UITabBarItem(title: "Steps", image: UIImage(named: "music.png"), tag: 1)

我认为您可能打算将导航控制器交给选项卡栏控制器，而不是

vc1

和

vc2

。比如：

tabBarVc.viewControllers=[nav1，nav2]

@Tyler，是的，它正在工作，谢谢，伙计。
