CocoaPods的安装(以下命令均在终端下操作)

1.安装方式简单,Mac下都自带ruby,使用ruby的gem命令即可下载安装:

sudo gem install cocoapods
pod setup

2.如果你的gem太老,可能也会有问题,可以尝试用如下命令升级gem:

sudo gem update --system

3.另外,ruby的软件源http://rubygems.org因为使用的是亚马逊的云服务,所以被墙了,需要更新一下ruby的源,使用如下代码将官方的ruby源替换成国内淘宝的源:

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

4.(验证)输入下面命令后,

gem sources -l

如果出现下面

*** CURRENT SOURCES ***

https://ruby.taobao.org/

5.此时就可以进行安装,

sudo gem install cocoapods

出现以下

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

CocoaPods的使用介绍

1.使用时需要(在想要加入第三方的工程下)新建一个名为Podfile的文件(先将工程路径拖进终端,使在此文件中创建)

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

2.然后将依赖的库(第三方)名字依次列在文件中

jinzhao:text lanou3g$ vim Podfile

//编写方式,如以下
pod 'SDWebImage','~>3.7'

终端进入
vim Podfile(如果存在直接打开,不存在创建后打开)
此时进入文件,如果是编辑模式,即可以进行编辑,或者是命令模式
编辑模式—>ESC+shift+冒号键+w键,此时可以写入
编辑模式—>ESC+shift+冒号键+q键,此时已经离开
编辑模式—>ESC+shift+冒号键+wq键,此时写入并离开
编辑模式—>ESC+shift+冒号键+wq!键,强制写入并离开
命令模式—>i键—>进入编辑模式
set nu:显示行号
ESC后 输入dd 可以删掉一行

3.然后编辑好的Podfile文件放到根目录中,执行如下命令即可:

cd "you project home"//此为将文件放到根目录,小编本就在根目录下创建,故此步骤可省略
pod install//圆荚体安装

4.得到,例如出现以下,即为加载完毕

Updating local specs repositories

[!] Please close any current Xcode sessions and use `text.xcworkspace` for this project from now on.

6.现在,你的所有第三方库都已经下载完成并且设置好了编译参数和依赖,你只需记住如下2点即可:

1.使用CocoPods生成的.xcworkspace文件来打开工程,而不是以前的.xcodeproj文件.2.每次更改了Podfile文件,你需要重新执行一次pod update命令.
