反应本机导航bottomTabNavigater和页眉

Question

我正在尝试进行应用导航，底部带有标签，页眉带有一些按钮。

我目前的设置如下：

AppNavigator.Js，其中具有用于登录和注册的SwitchNavigation。然后是Mainapp的StackNavgation，里面是TabNavigator。

#include <type_traits>

namespace is_iterable_impl
{
    template<class T>
    using check_specs = std::void_t<
        std::enable_if_t<std::is_same_v<
            decltype(begin(std::declval<T>())), // has begin()
            decltype(end(std::declval<T>()))    // has end()
        >>,                                     // ... begin() and end() are the same type ...
        decltype(*begin(std::declval<T>()))     // ... which can be dereferenced
    >;

    template<class T, class = void>
    struct is_iterable
    : std::false_type
    {};

    template<class T>
    struct is_iterable<T, check_specs<T>>
    : std::true_type
    {};
}

template<class T>
using is_iterable = is_iterable_impl::is_iterable<T>;

template<class T>
constexpr bool is_iterable_v = is_iterable<T>::value;

MainTabNavigator.js在这里，我有选项卡，每个选项卡都是一个StackNavigator。

const AppStack = createStackNavigator({
  Main: MainTabNavigator,
  Profile: ProfileScreen,
  UserSettings: SettingsScreen,
  Abo: AboScreen,
})

AppStack.navigationOptions = {
  headerRight: (
    <Button
      onPress={() => alert('This is a button!')}
      title="Info"
      color="#fff"
    />
  ),
}

{/* Navigation all the routes added here */}
export default createSwitchNavigator({
  Loading: AuthLoadingScreen,
  Welcome: WelcomeScreen,
  App: AppStack,
  Login: LoginScreen,
  SignUp: SignUpScreen,
  ForgotPassword: ForgotPasswordScreen,
});

我最终关注了Two Headers and cant add Icon to Header

如何禁用第二个标题，以及如何向标题添加按钮以向其中添加一些导航？
