前面我們學習了react-native-router-flux硫眯，接下來我們將使用其搭建微博主界面
react_native_router_flux_使用詳解一.php
react_native_router_flux_使用詳解二.php
react_native_router_flux_使用詳解三.php
第一步先來個簡單的主頁面切換
先上效果圖：
源碼已上傳碼云：https://git.oschina.net/osczaizai/RNWeiBo
根據(jù)前面的學習考杉，我們在本項目中通過npm將react-native-router-flux安裝到RNWeibo中褥傍，
npm i react-native-router-flux --save
