多人协作
######git 新建项目
1:将：podfile和.gitGore添加进去
2: 进入项目文件夹里：git init
3: pod install
4：git remote add origin 远程项目地址
5: 推送到远程：git push origin master
6:创建分支：git checkout -b 分支名字 origin/development
如果出现：fatal: remote origin already exists.
则：git remote rm origin
git remote add origin git@git.oschina.net:DSChina/Rongteng.git
git push -u origin master
