【水滴石穿】bstmy-blend-app

这个项目是一个简单的底部导航切换页面
项目的地址为：https://github.com/Bstmy/bstmy-blend-app
先看效果

点击首页是首页面，点击个人中心是个人中心页面
先看代码

//index.js
//引用的是根app.js
import {AppRegistry} from 'react-native';
import App from './app/App';
import {name as appName} from './app.json';
AppRegistry.registerComponent(appName, () => App);

//app/App.js
//这个里面不仅有防止闪屏的，还有倒计时为3的启动页，还有定义了首页
import React, { Component } from 'react';
//闪屏
import SplashScreen from 'react-native-splash-screen';
//导航
import {createAppContainer, createStackNavigator} from 'react-navigation';

//显示首页
import Home from "./Home";
//这个是很好看的启动页很美腻
import GuideView from "./guide/GuideView";
const RootStack = createStackNavigator(
    {
        homes: Home,
        guideView: GuideView
    },
    {
        initialRouteName: 'guideView'   ,
        defaultNavigationOptions: {
            headerStyle: {
                backgroundColor: '#f4511e',
                height:0,
            },
            headerTintColor: '#fff',

                fontWeight: 'bold',
            },
        },
    }
);
const AppContainer = createAppContainer(RootStack);
//定义首页
//渲染AppConta

//和index页面类似，不过具体怎么控制的？
//app/pages/User.js
import React, { Component } from 'react';

import {
    View,
    Text
} from 'react-native';

class User extends Component {

    render() {
        return (
            <View>

                <Text>
                    我是用户
                </Text>

            </View>
        );
    }
}

export default User;

上面有一点点的不理解
不知道是什么控制的切换的页面的，因为那个是同时引用的
不过这个项目我喜欢～～哭唧唧，在这个水平这里～～
