Question

我试图了解如何在嵌套堆栈中进行重置这是我的代码

    const AuthStack = createStackNavigator(
      {
        Welcome,
        Login,
        Register,
        ConfirmationCode,
      },
      {
        initialRouteName: 'Welcome',
        headerMode: 'none',
        lazy: true,
        transitionConfig,
        defaultNavigationOptions: {
          gesturesEnabled: false,
        },
      }
    )

    const AppStack = createStackNavigator(
      {
        TabStack,
        SearchResult,
        BusinessDetail,
        BusinessMap,
        MakeAppointment,
        TermsAndConditions
      },
      {
        initialRouteName: 'TabStack',
        headerMode: 'none',
        lazy: true,
        transitionConfig,
        defaultNavigationOptions: {
          gesturesEnabled: false,
        },
      }
    )

    let MainStack = createSwitchNavigator(
      {
        AuthLoading,
        Auth: AuthStack,
        App: AppStack,
      },
      {
        initialRouteName: 'AuthLoading',
        headerMode: 'none',
        lazy: true,

        defaultNavigationOptions: {
          gesturesEnabled: false,
        },
      }
    )

TabStack

    import React from 'react';

    import { createBottomTabNavigator, createAppContainer } from 'react-navigation';
    import {
        Search,
        MyFavourites,
        MyAppointments,
        UserProfile
    } from '../screens'
    import Icon from 'react-native-vector-icons/Feather';
    import Colors from '../utils/Colors'
    let TabStack = createBottomTabNavigator(
      {
        Search,
         MyFavourites,
         MyAppointments,
         UserProfile,
      },
        initialRouteName: 'ScreenTab1',
        tabBarOptions: {
          activeTintColor: Colors.pink,
          inactiveTintColor: Colors.black,
          showLabel: false,
          style: {
            backgroundColor: 'white'
          }
        },
      }
    )
    export default createAppContainer(TabStack);

例如，我想了解如何进行重置

    reset from UserProfile to TabStack (in AppStack) to AuthStack

我试图以此方式做

const resetAction = StackActions.reset({
        index: 0,
        actions: [NavigationActions.navigate({ routeName: 'AuthStack' })],
    });
    this.props.navigation.dispatch(resetAction);

或这种方式

const resetAction = StackActions.reset({
        index: 0,
        key: null,
        actions: [NavigationActions.navigate({ routeName: 'AuthStack' })],
    });
    this.props.navigation.dispatch(resetAction);

但是我得到了错误

没有为AuthStack定义路由

我检查了stackoverflow中的问题，但是那里的答案对我不起作用，总是向我显示我上面写的相同错误。

尝试将其设置为AppStack，因为无论如何，它都将重定向到GeneralStack，因为您在initialRouteName中将其命名为AppStack

const resetAction = StackActions.reset({
      index: 0,
      key: null,
      actions: [NavigationActions.navigate({ routeName: 'App' })],
    });
    this.props.navigation.dispatch(resetAction);

Answer 2

您的resetAction不成功，因为您是在TabStack上调度它（因为如果我正确理解的话，是因为您正在this.props.navigation.dispatch上调用UserProfile）。您需要将resetAction调度到MainStack。 This thread here提出了一些实现此目标的方法。而且，这是我的首选解决方案，因为我不必在导航器周围传递道具，也不必为此调用多个嵌套动作。

使用以下内容创建一个navigationService.js（以使您的顶级导航器作为参考）

import { NavigationActions, StackActions } from 'react-navigation';

let _navigator;

function setTopLevelNavigator(navigatorRef) {
  _navigator = navigatorRef;
}

function navigateMainNavigator(routeName, params) {
  _navigator.dispatch(
    NavigationActions.navigate({
      routeName,
      params,
    }),
  );
}

// add other navigation functions that you need and export them

export default {
  setTopLevelNavigator,
  navigateMainNavigator,
};

在App.js或呈现MainStack的任何其他文件上，执行此操作以设置引用

import NavigationService from './navigationService';

...

render() {
  return (

    ...
    <MainStack
      ref={navigatorRef => {
        NavigationService.setTopLevelNavigator(navigatorRef);
      }}
    />
    ...

  )
}

在任何要重置为AuthStack（或MainStack中任何其他堆栈）的地方，只需导入NavigationService并调用

NavigationService.navigateAndReset('Auth', {...yourParamsIfAny});
// 'Auth' because you named it that way in your 'MainStack'

navigationService.js中的先前解决方案是将StackNavigator用作MainStack

function navigateAndReset(routeName, params) {
  _navigator.dispatch(
    StackActions.reset({
      index: 0,
      actions: [
        NavigationActions.navigate({
          routeName,
          params,
        }),
      ],
    })
  );
}

您可以执行以下操作，以重置为authStack，

创建以下重置操作，

const resetAction = StackActions.reset({
  index: 0,
  actions: [NavigationActions.navigate({ routeName: "AuthStack" })],
  key: null
});
this.props.navigation.dispatch(resetAction);

，还将AuthStack添加到appStack或您要从其调用上述代码的堆栈中。

例如，如果您是从应用堆栈调用此代码，则将以下行添加为应用堆栈中的路由

  const AppStack = createStackNavigator(
  {
    TabStack,
    SearchResult,
    BusinessDetail,
    BusinessMap,
    MakeAppointment,
    TermsAndConditions,
    AuthStack <---Insert THIS
  },

在用于退出时，这对我有用。
