    ##设置npm镜像

    npm config set registry https://registry.npm.taobao.org --global
    npm config set disturl https://npm.taobao.org/dist --global

    (npm search失效,镜像地址修改回默认https://registry.npmjs.org/)

    ##设置yran镜像
    yarn config set registry https://registry.npm.taobao.org --global
    yarn config set disturl https://npm.taobao.org/dist --global

    ##安卓的需要android studio配置
    ##安装facebook的watchman
    brew install watchman
    (brew太慢的话可以切换)=>

        在~/.bashrc中加入 export HOMEBREW_BOTTLE_DOMAIN=http://7xkcej.dl1.z0.glb.clouddn.com
    ##初始化项目 react-native init projectName

    模拟器: ios: ⌘⇧+h =主键   

    fetch问题:
    ios9以上加入新特性App Transport Security (ATS),要求app访问网络必须为https
    解决办法:修改info.list
    <key>NSAppTransportSecurity</key>
        <dict>
            <key>NSAllowsArbitraryLoads</key>
              <true/>
        </dict>
    删除了这一段 -->NSAppTransportSecurity下(不知道为啥加上这一行,运行就白屏,并且不报错)
    <key>NSExceptionDomains</key>
    <dict>
    <key>demo.deepdot.com</key>
    <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    </dict>
    <key>localhost</key>
    <dict>
    <key>NSIncludesSubdomains</key>
    <true/>
    </dict>
    </dict>

     react-native中的 proptype报错
      PropTypes has been moved to a separate package. Accessing React.PropTypes is no longer supported and will be removed completely in React 16. Use the prop-types package on npm instead.
    使用第三方库prop-types代替,用来检查prop的类型是否合规
    用法:
     import PropTypes from 'prop-types' 
    /*假装这里有一个名为bilibili的类*/  bilibili.propTypes
    = {  name: PropTypes.string
      //bilibili类接受的prop定义限制为string,具体说明查看文档https://facebook.github.io/react/docs/typechecking-with-proptypes.html
     }
    react-native run-ios时报错:
    react native development, non-minified, hmr disabled
    
    解决办法:(版本问题)
    
        yarn remove babel-preset-react-native
    
        yarn add babel-preset-react-native@2.1.0
