react-native - 如果没有 react-navigation 的导航 Prop 和 react-i18next 容器，我无法导航

Question

我应用了 react-navigations 文档 (NavigationService) 中没有导航属性的导航示例，但我无法让它与 react- 一起工作i18next.

我应用了文档的例子https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html在我的代码中:

// App.js

import React from 'react';
import { Provider } from 'react-redux';
import { PersistGate } from 'redux-persist/lib/integration/react';
import { createAppContainer } from 'react-navigation';
import { I18nextProvider, withNamespaces } from 'react-i18next';
import { persistor, store } from './src/store';
import I18n from './src/localization';
import Navigation from './src/navigation';
import NavigationService from './src/navigation/NavigationService';
import Loader from './src/screens/components/Loader';

class NavigationStack extends React.Component {
  static router = Navigation.router;
  render() {
    const { t } = this.props;
    return <Navigation screenProps={{ t, I18n }} {...this.props} />;
  }
};

const ReloadNavOnLanguageChange = withNamespaces(['common', 'server'], {
  bindI18n: 'languageChanged',
  bindStore: false,
})(createAppContainer(NavigationStack));


export default class App extends React.Component {
  ...
  render() {
    return (
      <Provider store={store}>
        <PersistGate loading={<Loader />} persistor={persistor}>
          <I18nextProvider i18n={ I18n } >
            <ReloadNavOnLanguageChange ref={navigatorRef => {
              NavigationService.setTopLevelNavigator(navigatorRef);
            }} />
          </I18nextProvider>
        </PersistGate>
      </Provider>
    );
  };
};


// Navigation.js

...
export default Navigation = createSwitchNavigator(
  {
    AuthLoading: AuthLoadingScreen,
    Login: LoginScreen,
    App: AppScreen
  },
  {
    initialRouteName: 'AuthLoading'
  }
);


// NavigationService.js

Apply the same code that's in https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html


// Any JS module of my project (actions, helpers, components, etc.)

import NavigationService from 'path-to-NavigationService.js';
...
NavigationService.navigate('Login');

当验证授权 token 且结果是否定的时，必须打开登录屏幕 (NavigationService.navigate('Login')) 但它返回错误 _navigator.dispatch is不是 NavigationService.js 中的函数:

const navigate = (routeName, params) => {
   // DISPATCH ERROR
   _navigator.dispatch(
     NavigationActions.navigate({
       routeName,
       params
     })
   );
};

依赖关系:

• react 16.5.0
• native react 57.1
• react-i18next 9.0.0
• react 导航 3.1.2

有什么建议吗？还有其他人发现这种情况吗？

使用 react-i18next 的 withNamespaces hoc 的 innerRef 选项，而不是通过根组件的 ref 属性传递函数……正如 REACT-I18NETX 的文档所说!

// App.js

...
const ReloadNavOnLanguageChange = withNamespaces(['common', 'server'], {
  bindI18n: 'languageChanged',
  bindStore: false,
  innerRef: (ref) => NavigationService.setTopLevelNavigator(ref)
})(createAppContainer(NavigationStack));

export default class App extends React.Component {
  ...
  render() {
    return (
      ...
      <ReloadNavOnLanguageChange />
      ...
    );
  };
}
