在react native上的App.js中集成redux mapStateToProps

npm install redux react-redux

import React from 'react';
import { Provider } from 'react-redux';
import { createStore } from 'redux';
import rootReducer from './reducers'; // 导入根Reducer
import MyComponent from './MyComponent'; // 导入需要使用Redux的组件

const store = createStore(rootReducer);

const App = () => (
  <Provider store={store}>
    <MyComponent />
  </Provider>
);

import { connect } from 'react-redux';

const MyComponent = ({ data }) => (
  // 使用Redux的state
  <Text>{data}</Text>
);

const mapStateToProps = (state) => ({
  data: state.data // 将state中的data映射到组件的props上
});

export default connect(mapStateToProps)(MyComponent);
