一、概要

二、安裝

由於網上的教程基本都大同小異，但細節之處還不是很完善，所以藉機會在這裡補充下：

注：要使用CocoaPods，那就要下載安裝它，而下載安裝CocoaPods需要Ruby環境

1、Ruby環境搭建

當前安裝環境為Mac mini 10.10.5。Mac  OS本身自帶Ruby，但還是更新一下保險，因為我第一次安裝在沒有更新Ruby的情況下就失敗了。

a 檢視下當前ruby版本：開啟終端輸入 ruby -v（確實安裝了，不過用這個版本接下來工作失敗了，所以更新下ruby）

192:~ WangLimin$ ruby -v

ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]

192:~ WangLimin$ sudo gem install cocoapods

We trust you have received the usual lecture from the local System

Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.

    #2) Think before you type.

    #3) With great power comes great responsibility.

ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:

          Unable to download data from https://rubygems.org/ - Errno::EPIPE: Broken pipe - SSL_connect (https://rubygems.org/latest_specs.4.8.gz)

b 更新ruby

終端輸入如下命令（把Ruby映象指向taobao，避免被牆，你懂得）

gem sources --remove https://rubygems.org/ 
gem sources -add https://ruby.taobao.org/ 
gem sources -l  （用來檢查使用替換映象位置成功）

192:~ WangLimin$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/

https://ruby.taobao.org/ added to sources

https://rubygems.org/ removed from sources

192:~ WangLimin$ gem sources -l

*** CURRENT SOURCES ***

https://ruby.taobao.org/

2、下載安裝CocoaPods

終端輸入：sudo gem install cocoapods 

然後輸入電腦密碼，開始下載安裝

192:~ WangLimin$ sudo gem install cocoapods

這樣就下載安裝好了CocoaPods

3、使用CocoaPods

a  新建一個專案，名字PodTest

b  終端中，cd到專案總目錄（注意：包含PodTest資料夾、PodTest.xcodeproj、PodTestTest的那個總目錄）

c  建立Podfile（配置檔案）

接著上一步，終端輸入 vim Podfile

192:PodTest WangLimin$ vi podfile

platform :iOS,'9.0'

pod 'MBProgressHUD', '~> 0.8'

回車後發現PodTest專案總目錄中多一個Podfile檔案

激動人心的時刻到了：確定終端cd到專案總目錄，然後輸入 pod install，等待一會，大約3分鐘。

192:PodTest WangLimin$ pod install

Creating shallow clone of spec repo `master` from `https://github.com/CocoaPods/Specs.git`

CocoaPods 1.0.0.beta.6 is available.

To update use: `gem install cocoapods --pre`

[!] This is a test version we'd love you to try.

For more information see http://blog.cocoapods.org

and the CHANGELOG for this version http://git.io/BaH8pQ.

Sending stats

Pod installation complete! There is 1 dependency from the Podfile and 1

total pod installed.

192:PodTest WangLimin$ 

檢視專案根目錄：

注意：現在開啟專案不是點選 PodTest.xodeproj了，而是點選 PodTest.xcworkspace

開啟專案後看到專案結構並且測試一下：

執行結果：

補充：

1、CocoaPods的基本安裝及使用都詳細的說明了，但還有一些補充，當需要同時匯入多個第三方時候怎麼辦 ？

這就需要修改Podfile了，就是用vim編輯的那個儲存在專案根目錄中的檔案，修改完了Podfile檔案，需要重新執行一次pod install命令。

例如：

platform :ios

pod 'JSONKit',       '~> 1.4'

pod 'AFNetworking',  '~> 2.0'

終端輸入命令：pod search UI

瘋了了，我怎麼查詢這麼大眾的關鍵字，好多庫～～

然後重新編輯Podfile檔案，按照之前的步驟，把更多的庫都匯入專案！

/////////////////////////////////
Cocoapods解除安裝安裝

Cocoapods存在兩個版本 一個0.39.0 一個1.0.1 
所以把這兩個都刪了
sudo gem uninstall cocoapods -v0.39.0
sudo gem uninstall cocoapods -v1.0.1

之後重新安裝一個版本
sudo gem install cocoapods -v0.39.0
