正式创建项目：

python cocos.py new -p cf.icbd.www -l cpp -d /Users/baodong/__TEST__/Cocos_TEST HelloCC

参数解释：
-p 包名
-l 项目所用语言『Cpp/Lua/JavaScript』
-d 项目存放路径
最后跟新项目名称

编译运行

进入 HelloCC/proj.ios_mac 目录

CBD-MBP:proj.ios_mac baodong$ ls -a
.                 .DS_Store         ios
..                HelloCC.xcodeproj mac

用Xcode点击打开 HelloCC.xcodeproj
直接点击左上角运行即可。
速度比windows下速度快不少，几十秒内编译完成，自动启动模拟器。
