安装react native:按照官网 http://facebook.github.io/react-native/docs/getting-started.html

brew install node#安装node watchman flow
brew install watchman#:遇到xz需要重新安装问题，于是brew install xz
brew install flow
sudo npm install -g react-native-cli#安装 react-native本身 mac需要sudo
sudo react-native init AwesomeProject#输入命令建立工程

利用xcode打开当前目录的AwesomeProject
commond＋r两次则可以运行
