CocoaPods 安装 使用

1.开启 terminal

2.移除现有 Ruby 默认源

$ gem sources --remove https://rubygems.org/

3.使用新的源

$ gem sources -a https://ruby.taobao.org/

4.验证新源是否替换成功

$ gem sources -l

5.安装 CocoaPods

$ sudo gem install cocoapods

$ pod setup

备注：苹果系统升级 OS X EL Capitan 后安装改为:

$ sudo gem install -n /usr/local/bin cocoapods

$ pod setup

6.更新 gem

$ sudo gem update --system

7.新建工程，并在终端用 cd 指令到文件夹内

$ pod search 第三方

8.新建 Podfile 文件

$ touch Podfile

9.编辑 Podfile 文件，并写入要添加的第三方库

platform:ios, '8.0'

pod 'AFNetworking', '~> 2.3.1'<-------第三方

10.导入第三方库

$ pod install

$ pod install --verbose --no-repo-update

11.退出终端

可能遇到的错误提示及解决方法：

Error 1：

Error fetching http://ruby.taobao.org/:

bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)

解决方案：把安装流程中 $ gem sources -a http://ruby.taobao.org/ 

改为：$ gem sources -a https://ruby.taobao.org/

Error 2：

ERROR:  While executing gem ... (Errno::EPERM)

Operation not permitted - /usr/bin/pod

解决方案：苹果系统升级 OS X EL Capitan 后会出现的插件错误，将安装流程 5.安装 CocoaPods 的 sudo gem install cocoapods

改为 sudo gem install -n /usr/local/bin cocoapods

Error 3：

[!] Unable to satisfy the following requirements:

- `AFNetworking (~> 2.3.1)` required by `Podfile`

Specs satisfying the `AFNetworking (~> 2.3.1)` dependency were found, but they required a higher minimum deployment target.

解决方案：Podfile 文件 中   platform:ios, ‘8.0’  后边的 8.0 是平台版本号 ，一定要加上
