reactjs – 使用反应导航将导航历史记录重置为登录屏幕

const actionToDispatch = NavigationActions.reset({
            index: 0,actions: [NavigationActions.navigate({ routeName: 'Home' })]
        });

        this.props.navigation.dispatch(actionToDispatch);

这工作正常.按下注销后,用户应该返回欢迎,但它不起作用.这就是我在做什么：

const resetAction = NavigationActions.reset({
            index: 0,actions: [
                NavigationActions.navigate({ routeName: 'Welcome' }),]
        });

        this.props.navigation.dispatch(resetAction);

该错误表示没有“欢迎”的路线.必须是“主要”,“隐私”,“条款”之一,它们是主页中某个标签的路线.见下文：

const AppStack = StackNavigator({
                    Welcome: {
                        screen: Welcome
                    },Home: {
                        screen: Tabs
                    }
                },{
                        initialRouteName: this.state.isLoggedIn ? 'Home' : 'Welcome',headerMode: 'none'
                    }
                );

export const ProfileStack = StackNavigator({
    Profile: {
        screen: Profile,},});

export const SettingsStack = StackNavigator({
    Settings: {
        screen: Settings,{
    });

export const InfoStack = StackNavigator({
    Main: {
        screen: Main,Privacy: {
        screen: Privacy
    },Terms: {
        screen: Terms
    }
});

const routeConfiguration = {

    Profile: { screen: ProfileStack },Settings: { screen: SettingsStack },Info: { screen: InfoStack }
};

const tabBarConfiguration = {
    tabBarOptions: {
        activeTintColor: 'white',inactiveTintColor: 'lightgray',labelStyle: {
            fontSize: Normalize(10),fontFamily: Fonts.book
        },style: {
            backgroundColor: Colors.greenLightGradient,borderTopWidth: 1,borderTopColor: Colors.tabGreenLine
        },}
};

export const Tabs = TabNavigator(routeConfiguration,tabBarConfiguration);
