我是React-Native的新手,我正在尝试使用stackNavigation和React-Redux实现一个简单的应用程序,并带有欢迎和注册屏幕。我已经使用StackNavigation配置了两个屏幕,但是出于某些原因,仅在应用程序启动时弹出注册屏幕。以下是我的文件:
index.js
import { AppRegistry } from 'react-native';
import App from './App';
AppRegistry.registerComponent('MyApp', () => App);
app.js
import React, { Component } from 'react';
import { Provider, connect } from "react-redux";
import { addNavigationHelpers } from "react-navigation";
import StackNavConfig from "./js/config/routes";
import getStore from "./js/store";
const AppNavigator = StackNavConfig;
const initialState = AppNavigator.router.getActionForPathAndParams('Welcome');
const navReducer = (state = initialState, action) => {
const newState = AppNavigator.router.getStateForAction(action, state);
return newState || state;
};
const AppWithNavigationState = connect(state => ({
nav: state.nav,
}))(({ dispatch, nav }) => (
<AppNavigator navigation={addNavigationHelpers({ dispatch, state: nav })} />
));
const store = getStore(navReducer);
class App extends React.Component {
render() {
return (
<Provider store={store}>
<AppWithNavigationState />
</Provider>
);
}
}
export default App;
JS/config/coundes.js
import Welcome from "../components/Welcome/view/Welcome";
import SignUp from "../components/SignUp/view/SignUp";
import { StackNavigator } from "react-navigation";
const Routes = {
Welcome: { screen: Welcome , path: ''},
SignUp: { screen: SignUp , path : '/signup'},
};
const RoutesConfig = {
initialRouteName: 'Welcome',
headerMode: 'none',
};
export default StackNavConfig = StackNavigator(Routes, RoutesConfig);
store.js
import { createStore, applyMiddleware } from "redux";
import thunk from "redux-thunk";
import getRootReducer from "./reducers/index";
export default function getStore(navReducer) {
const store = createStore(
getRootReducer(navReducer),
undefined,
applyMiddleware(thunk)
);
return store;
}
下面是我的组件欢迎.js
import React from 'react';
import {
View,
Image} from 'react-native';
import { connect } from "react-redux";
import { bindActionCreators } from "redux";
import * as welcomeActions from "../actions/WelcomeActions";
import { welcomeStyles } from '../styles/WelcomeStyles';
class Welcome extends React.Component {
constructor(){
super();
this.state = { };
}
render(){
return (
<View style = {welcomeStyles.mainContainer}>
<Text>Welcome</Text>
</View>
);
}
}
export default connect(
state => ({
}),
dispatch => bindActionCreators(welcomeActions, dispatch)
)(Welcome);
Ingip.js
import React from 'react';
import {
View,
Image} from 'react-native';
import { connect } from "react-redux";
import { bindActionCreators } from "redux";
import * as welcomeActions from "../actions/SignUpActions";
import { signUpStyles } from '../styles/SignUpStyles';
class Welcome extends React.Component {
constructor(){
super();
this.state = { };
}
render(){
return (
<View style = {signUpStyles.mainContainer}>
<Text>SignUp</Text>
</View>
);
}
}
export default connect(
state => ({
}),
dispatch => bindActionCreators(signUpActions, dispatch)
)(SignUp);
我也有每个组件的动作和还原文件。但是到目前
import { combineReducers } from "redux";
import welcomeReducer from "../components/Welcome/reducers/WelcomeReducer";
import signUpReducer from "../components/SignUp/reducers/SignUpReducer";
export default function getRootReducer(navReducer) {
return combineReducers({
nav: navReducer,
welcomeReducer : welcomeReducer,
signUpReducer : signUpReducer,
});
}
如前所述,即使设置了initialRoutEname在我的路由中欢迎,每次我启动app 时,注册屏幕都会出现。请帮助
我发现了什么问题。我在渲染函数内部错误地呼叫this.props。
