CocoaPods / Pod 安装简略步骤
项目中用到CocoaPods来管理第三方库文件，这就需要安装，首先说吧，网上一大片安装方法和使用，但是经过一番折腾，组合查询，最终能安装成功并运行Xcode 工程，这里将简要罗列安装步骤，便于快速安装，至于每一步为什么这样，请不要问我，网上已经有大量描述，后面我会给出参考文章（标注-红色为我们手动输入，黑色为命令行自己输出）：
第一步骤：
mapboo:~ mapboo$ gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
mapboo:~ mapboo$ gem sources -a http://ruby.taobao.org/
http://ruby.taobao.org/ added to sources
mapboo:~ mapboo$ gem sources -l
*** CURRENT SOURCES ***
http://ruby.taobao.org/
mapboo:~ mapboo$ sudo gem install cocoapods

至此，第一步安装成功，参考： http://code4app.com/article/cocoapods-install-usage。
第二步骤：
mapboo:XX_Project mapboo$ pod install --verbose --no-repo-update
Preparing
Analyzing dependencies
Inspecting targets to integrate
Using `ARCHS` setting to build architectures of target `Pods`:
(`$(ARCHS_STANDARD)`)
Finding Podfile changes
- pop
Resolving dependencies of `Podfile`
Creating shallow clone of spec repo `master` from `https://github.com/CocoaPods/Specs.git`
$ /usr/bin/git clone 'https://github.com/CocoaPods/Specs.git' master --depth=1
Cloning into 'master'...
Checking out files: 100% (24223/24223), done.
.
Comparing resolved specification to the sandbox manifest
- pop
Downloading dependencies
-> Using pop (1.0.7)
- Running pre install hooks
Generating Pods project
- Creating Pods project
- Adding source files to Pods project
- Adding frameworks to Pods project
- Adding libraries to Pods project
- Adding resources to Pods project
- Linking headers
- Installing targets
- Installing target `Pods-pop` iOS 6.0
- Installing target `Pods` iOS 6.0
- Running post install hooks
- Writing Xcode project file to `Pods/Pods.xcodeproj`
- Writing Lockfile in `Podfile.lock`
- Writing Manifest in `Pods/Manifest.lock`
Integrating client project
Integrating target `Pods` (`customer/customer.xcodeproj` project)
[!] The `customer [Debug]` target overrides the `CLANG_CXX_LIBRARY` build setting defined in `../Pods/Target Support Files/Pods/Pods.debug.xcconfig'. This can lead to problems with the CocoaPods installation
- Use the `$(inherited)` flag, or
- Remove the build settings from the target.
[!] The `customer [Release]` target overrides the `CLANG_CXX_LIBRARY` build setting defined in `../Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
- Use the `$(inherited)` flag, or
- Remove the build settings from the target.
//XX_Project: 是你的项目工程所在文件夹
