有没有办法改变UINavigationController Swift Xcode中UINavigationBar的高度？

class CustomNavigationBar: UINavigationBar {
    override var intrinsicContentSize: CGSize {
        return CGSize(width: UIView.noIntrinsicMetric, height: 100) // 设置为100，可以根据需要进行调整
    }
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 创建自定义的UINavigationBar
    let customNavigationBar = CustomNavigationBar(frame: CGRect.zero)
    
    // 设置为全局的UINavigationBar外观
    UINavigationBar.appearance().subclass(for: CustomNavigationBar.self)
    
    // 创建并设置根视图控制器
    let rootViewController = UIViewController()
    let navigationController = UINavigationController(rootViewController: rootViewController)
    navigationController.navigationBar = customNavigationBar
    
    // 设置为根视图控制器
    window?.rootViewController = navigationController
    window?.makeKeyAndVisible()
    
    return true
}
