在基于故事板的应用程序中禁用/启用UITabBarController中的选项卡

// 获取UITabBarController实例
let tabBarController = UITabBarController()

// 设置选项卡初始状态
tabBarController.tabBar.items = [
    UITabBarItem(title: "Tab 1", image: UIImage(named: "tab1"), tag: 1),
    UITabBarItem(title: "Tab 2", image: UIImage(named: "tab2"), tag: 2),
    UITabBarItem(title: "Tab 3", image: UIImage(named: "tab3"), tag: 3)
]

// 设置UITabBarController的delegate
tabBarController.delegate = self

// 显示UITabBarController
present(tabBarController, animated: true, completion: nil)

// 获取UITabBarController实例
let tabBarController = UITabBarController()

// 设置选项卡初始状态
tabBarController.tabBar.items = [
    UITabBarItem(title: "Tab 1", image: UIImage(named: "tab1"), tag: 1),
    UITabBarItem(title: "Tab 2", image: UIImage(named: "tab2"), tag: 2),
    UITabBarItem(title: "Tab 3", image: UIImage(named: "tab3"), tag: 3)
]

// 设置UITabBarController的delegate
tabBarController.delegate = self

// 隐藏UITabBarController中的选项卡
tabBarController.tabBar.isHidden = true

extension YourViewController: UITabBarControllerDelegate {
    func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
        // 返回true以允许该viewController成为所选选项卡，返回false以阻止该viewController成为所选选项卡
        return true
    }
}
