一、HomeBrew相关：
先对HomeBrew做一个简单的介绍吧，之前了解的也不多。
主要就是用于安装Unix的工具包。
注意：HomeBrew依赖于Xcode的 Command Line Tool.

Homebrew作为OS X上强大的包管理器，为系统软件提供了非常方便的安装方式，独特式的解决了包的依赖问题，并不再需要烦人的sudo，一键式编译，无参数困扰，真的，你值得拥有。
安装
Homebrew依赖于XCode，首先需要安装，lion后XCode也是免费的了，直接到App store下载。同时Homebrew也依赖ruby，Mac已经自带ruby。
使用
查看brew的帮助安装软件卸载软件搜索软件显示已经安装软件列表更新软件，把所有的Formula目录更新，并且会对本机已经安装并有更新的软件用*标明。更新某具体软件查看软件信息删除程序，和upgrade一样，单个软件删除和所有程序老版删除。查看那些已安装的程序需要更新程序安装路径及文件夹
Homebrew将本地的/usr/local初始化为git的工作树，并将目录所有者变更为当前所操作的用户，以后的操作将不需要sudo。
HomeBrew与MacPorts的比较，貌似MacPorts会被人逐渐遗弃

二、XCTool相关
xctool是facebook开源的一个命令行工具，用来替代苹果的xcodebuild工具。
功能如下：
像xcode一样跑测试用例结构化输出编译测试结果彩色且方便阅读的编译内容输出
示例截图：
如何安装xctool
最简单的办法是通过homebrew安装xctool
brew updatebrew install xctool
搞定
如何使用xctool
打包
path/to/xctool.sh \-workspace YourWorkspace.xcworkspace \-scheme YourScheme \archive
build
path/to/xctool.sh \-workspace YourWorkspace.xcworkspace \-scheme YourScheme \build
测试
path/to/xctool.sh \-workspace YourWorkspace.xcworkspace \-scheme YourScheme \test
使用命令如下，上面的命令参照
切换到工程目录下，然后输入如下命令：
xctool -workspace taoappios.xcworkspace -scheme taoappios archive
生成archive文件
xctool -workspace taoappios.xcworkspace -scheme taoappios build
编译
usage: xctool [BASE OPTIONS] [ACTION [ACTION ARGUMENTS]] ...
Examples:
xctool [BASE OPTIONS] clean
xctool [BASE OPTIONS] build
xctool [BASE OPTIONS] build-tests [-only TARGET] [-skip-deps]
xctool [BASE OPTIONS] run-tests [-test-sdk SDK] [-only SPEC] [-freshSimulator] [-freshInstall]
xctool [BASE OPTIONS] test [-test-sdk SDK] [-only SPEC] [-skip-deps] [-freshSimulator] [-freshInstall]
xctool [BASE OPTIONS] archive
Base Options:
-help show help
-workspace PATH path to workspace
-project PATH path to project
-scheme NAME scheme to use for building or testing
-find-target TARGET Search for the workspace/project/scheme to build the target
-find-target-path PATH Path to search for -find-target.
-find-target-exclude-pathColon-separated list of paths to exclude for -find-target.
