理解 Xcode 中的 Git 版本控制 http://www.open-open.com/lib/view/open1399179356984.html
xcode提交版本时提示The working copy "MyPro" failed to commit files.
*** Please tell me who you are.
Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address
解决办法：
打开终端，进入自己的项目下，有个.git目录
cd ~/MyPro/.git
vi config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
ignorecase = true
#添加以下三行：
[user]
email = yourname@me.com
name = yourname
