iOS应用程序如何自定义导航的高度？

override func viewDidLoad() {
    super.viewDidLoad()
    
    let navBarHeight: CGFloat = 100 // 设置导航栏的高度
    let statusBarHeight = UIApplication.shared.statusBarFrame.height
    let customNavBarFrame = CGRect(x: 0, y: statusBarHeight, width: view.frame.width, height: navBarHeight)
    
    let customNavBar = UINavigationBar(frame: customNavBarFrame)
    customNavBar.backgroundColor = .white // 设置导航栏的背景颜色
    customNavBar.tintColor = .black // 设置导航栏的按钮颜色
    
    view.addSubview(customNavBar)
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    let rootViewController = YourViewController()
    let navigationController = CustomNavigationController(rootViewController: rootViewController)
    
    window?.rootViewController = navigationController
    window?.makeKeyAndVisible()
    
    return true
}
