项目使用cocapod的步骤及注意事项：
（主要是针对之前就安装使用过，但是许久不用，忘掉部分的。关于初次使用cocoapod的使用，网上有许多教程，按照教程，基本没什么问题！！！）
因为之前安装过cocoapod的，所以直接打开终端
1、cd到新建项目所在目录下
2、touch Podfile－－创建Podfile文件
3、open -e Podfile－－打开这个文件进行编辑
类似：
platform :ios,'8.0'
#use_frameworks!个别需要用到它，比如reactiveCocoa
target'MyApp'do
pod'AFNetworking','~> 2.6'
pod'ORStackView','~> 3.0'
pod'SwiftyJSON','~> 2.3'
end
与之前已经不同！！！PS：里面的 MyApp 记得替换为自己项目的target
参考http://blog.csdn.net/sjl_leaf/article/details/50506057，
4、执行pod install
备注：
我在执行pod search AFNetworking 的时候按常规应该出现AFNetworking的相关描述，但是现在一直报错

- pod search not work JSON ParserError

这个错误 目前也没找到相关的解决方案，但是值得庆幸的是不影响项目中对cocoapod的使用！！
可以参考：
https://github.com/CocoaPods/CocoaPods/issues/5172
应该是~/Library/Caches/CocoaPods/search_index.json这个文件的问题.
可以使用 rm ~/Library/Caches/CocoaPods/search_index.json 删除后再pod search xxx 会自动重建的.
