Cocoapod是一个强大的第三方的开源框架的管理工具,其中的各种开源类库,很多都是持续更新;那么我们在使用的时候就可以使用到最新的类库;由于我们在使用开源框架的时候,也难免会遇到 第三方类库可能会出现的Bug,或者由于苹果的SDK更新,各种框架也需要更新,使用Cocoapods的话就可以一键更新到最新的开源框架了!
首先就是要安装Cocoapos了,安装它需要ruby环境,但是较新的Mac 系统已经为我们安装好了ruby,所以我们现在可以直接安装Cocoapods啦!
安装Cocoapods步骤:
1.打开终端,设置root密码
执行如下命令来设置root密码(如果你没有设置root密码的话)
sudo passwd rootNew password:Retype new password:输入密码并且确认即可
2.安装Cocoapods
(1)执行命令:
su输入密码切换到root用户
(2)执行:
gem sources –remove https://rubygems.org/待有反应(输出
https://rubygems.org/ removed from sources
)(3)然后执行:
gem sources -a (输出是
added to sources
)
(4)查看是否关联到镜像,执行
gem sources -l(输出
*** CURRENT SOURCES ***
,代表执行之前的命令是成功的)(5)安装Cocoapods,执行
sudo gem install cocoapods可能需要等待几分钟,Cocoapods库就安装好了,输出如下:

exit退出root用户,因为Cocoapods默认不能在root上正常的使用
pod会输出:
sh-3.2# exitexitmacios:~ mac$ podUsage:$ pod COMMANDCocoaPods, the Cocoa library package manager.Commands:+ initGenerate a Podfile for the current directory.+ install Install project dependencies to Podfile.lock versions+ ipcInter-process communication+ libDevelop pods+ listList pods+ outdated Show outdated project dependencies+ plugins Show available CocoaPods plugins+ repoManage spec-repositories+ searchSearches for pods+ setupSetup the CocoaPods environment+ specManage pod specs+ trunkInteract with the CocoaPods API (e.g. publishing new specs)+ tryTry a Pod!+ updateUpdate outdated project dependencies and create newPodfile.lockOptions:–silentShow nothing–version Show the version of the tool–verbose Show more debugging information–no-ansi Show output without ANSI codes–helpShow help banner of specified commandmacios:~ mac$ 输出如上,代码Cocoapods安装成功!
3.使用Cocoapods
首先新建一个ios工程如FirstApp,然后关闭工程[此点很重要,否则会无法正常使用Cocoapods安装类库],切换到工程的根目录(拖拽工程文件夹可以快速的切换)
(1)执行
cd /Users/mac/Desktop/FirstApp(你的工程根目录路径)(2)执行
pod init执行完成之后,会在根目录下创建一个文件:Podfile(3)搜索你需要的类库,只需输入部分字符串即可,自动查找
比如我们来搜索一下AFNetworking类库,执行:
pod search afnet如果是第一次使用Cocoapods搜索的话会满一些,稍等一下,即可看到很多的AF相关的内容出来了,其中有我们想要的AFNetworking框架
部分输出如下:
学做任何事得按部就班，急不得
