CocoaPods是iOS项目的依赖管理工具。使用它不需要我们自己去下载第三方开源库的代码并且放进自己的项目中，它会将第三方开源库的代码下载下来并且设置好相应的系统依赖和编译参数。
安装
- 设置ruby源: ruby的软件源rubygems.org因为使用亚马逊的云服务，在国内不能使用，所以要更换ruby源。
打开终端:
terminal.png
- 查看当前ruby源:
gem sources
结果:
gemsources.png
当前我的mac上的ruby源为:
https://gems.ruby-china.org/
我这是更换后的，如果你的是:
https://rubygems.org/
需要更换为前者。
- 移除当前ruby源:
gem sources --remove https://rubygems.org/
gemsourcesremove.png
- 添加新的ruby源:
gem sources -a https://gems.ruby-china.org/
gemsourcesa.png
再次查看当前ruby源，已经更换:
curren.png
- 查看当前gem版本:
gem -v
version.png
- 如果gem版本过低，可以尝试以下方式升级:
使用命令:
gem update --system
报错:
macdeMacBook-Pro:~ mac$ gem update --system
Updating rubygems-update
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
这个暂时没理会，换个命令:
sudo gem update --system
仍然报错:
macdeMacBook-Pro:~ mac$ sudo gem update --system
Password:
Updating rubygems-update
ERROR: While executing gem ... (OpenSSL::SSL::SSLError)
hostname "upyun.gems.ruby-china.org" does not match the server certificate
Password:处我输入的为开机密码，不清楚到底是不是。
接着我又执行一次刚才的命令:sudo gem update --system
然后，升级成功了！

- 安装:
pod setup
这里会在Setting up CocoaPods master repo这个状态等待一段时间:

安装报错:
error.png
这可能与网络状态有关系，重试了3次后安装成功。
completed.png
使用
为了更好的说明使用方式: 新建一个工程，名称为CocoaPodsTest，目录结构:
content.png
-
在工程根目录下新建一个Podfile文件，名字必须是Podfile。
-
可以创建文件再放在工程根目录下
-
终端进入工程根目录，执行touch Podfile命令创建:
-
touchpodfile.png
podfile.png
- 打开Podfile文件(命令: open -e Podfile): 第一次打开此文件是个空白页面，其内容格式应该配置为如下样式:
platform :ios, '7.0'
target 'CocoaPodsTest' do
pod 'AFNetworking', '~> 2.0'
pod 'Masonry'
pod 'SDWebImage'
pod 'MJRefresh'
end
其中platform为配置平台，ios必须是小写且与之前的":"不能有空格，后面的'7.0'为最低iOS SDK版本号，有些第三方库要求最低版本。
其中AFNetworking后面的2.0为当前要引入的AFNetworking版本，如果不写，默认为该第三方开源库的最新版本。
- 配置好Podfile文件后保存，在工程根目录下终端执行命令: pod install
install.png
绿色文字，提醒我们以后打开项目的时候应该打开生成的CocoaPodsTest.xcworkspace。
content.png
目录.png
如果终端中报黄色字体:
signerror.png
[!] Smart quotes were detected and ignored in your Podfile. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.
可能是你输入的单引号不正确，检查是不是输入了中文的单引号。
补充:
使用第三方库，使用#import引入第三方库头文件时，发现不提醒，command + B编译多次仍不提醒。
解决方法:
工程 -> TARGETS -> Build Settings -> Search Paths -> User Header Search Paths:
双击User Header Search Paths后的空白处，点击"+"号，输入"$(PODS_ROOT)"，修改搜索方式为recursive(递归方式查找)。
header.png
这样在引入头文件时就会自动联想出第三方库的头文件了。
删除之前引入的某个第三方库
在工程中找到Podfile文件，注销掉想要删除的某个开源库
podfilexcode.png
，也可以直接打开Podfile文件，直接删除某个开源库，
podfile.png
再在终端中执行一次pod install命令，成功后即可删除开源库。
delete.png
PS: mac系统升级为High Sierra后发现CocoaPods不能用了，执行pod install命令时，报错: -bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad ...
然后我直接照着本教程重新更新ruby版本、重新安装了cocoaPods。
