React Navigation：如何使用子堆栈中的特定选项卡返回根选项卡导航器

Question

我在 React Native 中使用react-navigation v2，每当想要返回根导航器中的特定选项卡时都会卡住。

我有以下路线堆栈：

const HomeStack = createStackNavigator(
  {
    Home: Home,
    CreateInvoice: CreateInvoiceScreen,
    InvoiceSummary: InvoiceSummaryScreen,
    PinEntry: PinEntryScreen
  },
  {
    navigationOptions: {
      header: null
    }
  }
);

const CustomersStack = createStackNavigator(
  {
    Customers: CustomersScreen,
    Details: CustomerDetailsScreen
  },
  {
    navigationOptions: {
      header: null
    }
  }
);

const Tab = createBottomTabNavigator(
  {
    Home: HomeStack,
    Transactions: TransactionsTab,
    Customers: CustomersStack,
    Settings: SettingsTab
  }
);

const Routers = createStackNavigator({
  splash: {
    screen: SplashScreen,
    navigationOptions: {...navigationOptions}
  },
  login: {
    screen: LoginScreen,
    navigationOptions: {...navigationOptions}
  },
  home: {
    screen: HomeScreen,
    navigationOptions: {...navigationOptions}
  }
});

我现在在PinEntry屏幕中，我想返回到TabNavigator 中的Transactions选项卡。我可以使用以下脚本返回主页选项卡：

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

但我的目标是回到特定的标签位置，在这种情况下是“交易”标签。

我已经用谷歌搜索了很多次，但没有解决方案，任何帮助将不胜感激。

我找到了解决方案：

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