CocoaPods的安裝和使用介紹

CocoaPods的安裝(如下命令均在終端下操做)

1.安裝方式簡單,Mac下都自帶ruby,使用ruby的gem命令便可下載安裝:

sudo gem install cocoapods
pod setup

2.若是你的gem太老,可能也會有問題,能夠嘗試用以下命令升級gem:

sudo gem update --system

3.另外,ruby的軟件源http://rubygems.org由於使用的是亞馬遜的雲服務,因此被牆了,須要更新一下ruby的源,使用以下代碼將官方的ruby源替換成國內淘寶的源:

gem sources --remove http://rubygems.org/
gem sources -a https://ruby.taobao.org/
gem sources -l

4.(驗證)輸入下面命令後,

gem sources -l

若是出現下面

*** CURRENT SOURCES ***

https://ruby.taobao.org/

5.此時就能夠進行安裝,

sudo gem install cocoapods

出現如下

Successfully installed cocoapods-0.39.0
Parsing documentation for cocoapods-0.39.0
1 gem installed

CocoaPods的使用介紹

1.使用時須要(在想要加入第三方的工程下)新建一個名爲Podfile的文件(先將工程路徑拖進終端,使在此文件中建立)

cd /Users/lanou3g/Desktop/未命名文件夾/text
jinzhao:text lanou3g$ touch Podfile

2.而後將依賴的庫(第三方)名字依次列在文件中

jinzhao:text lanou3g$ vim Podfile

//編寫方式,如如下
pod 'SDWebImage', '~>3.7'

終端進入
vim Podfile(若是存在直接打開,不存在建立後打開)
此時進入文件,若是是編輯模式,便可以進行編輯,或者是命令模式
編輯模式—>ESC+shift+冒號鍵+w鍵,此時能夠寫入
編輯模式—>ESC+shift+冒號鍵+q鍵,此時已經離開
編輯模式—>ESC+shift+冒號鍵+wq鍵,此時寫入並離開
編輯模式—>ESC+shift+冒號鍵+wq!鍵,強制寫入並離開
命令模式—>i鍵—>進入編輯模式
set nu:顯示行號
ESC後 輸入dd 能夠刪掉一行

3.而後編輯好的Podfile文件放到根目錄中,執行以下命令便可:

cd "you project home"//此爲將文件放到根目錄,小編本就在根目錄下建立,故此步驟可省略
pod install//圓莢體安裝

4.獲得,例如出現如下,即爲加載完畢

6.如今,你的全部第三方庫都已經下載完成而且設置好了編譯參數和依賴,你只需記住以下2點便可:

1.使用CocoPods生成的.xcworkspace文件來打開工程,而不是之前的.xcodeproj文件.
2.每次更改了Podfile文件,你須要從新執行一次pod update命令.
