在导入某个框架时,你可能还需要导入这个框架依赖的其他框架,这样就比较麻烦。如果用CocoaPods导入一个框架,它会自动导入这个框架所依赖的所有框架。在导入AFNetworking时用到了它,这里总结了安装方法及一些需要注意的细节。
CocoaPods安装
- 安装ruby环境,下面的所有操作都在终端(Terminal)下输入命令执行
gem source -a https://gems.ruby-china.com
- 检查上面命令是否执行成功
gem sources -l
# 执行结果:
# kevindeMacBook-Air:~ kevin$ gem sources -l
# *** CURRENT SOURCES ***
# https://gems.ruby-china.com/
- 安装CocoaPods,这里需要等一会
sudo gem install cocoapods
执行结果:
kevindeMacBook-Air:~ kevin$ sudo gem install cocoapods

- 检查CocoPods是否安装成功,终端下直接输入pod命令,会显示帮助内容,如下图:
用CocoaPods导入AFNetworking框架到Xcode项目
- 搜索AFNetworking框架,这里好像会更新一些东西。出现Setting up CocoPods master repo,要等很久,如果有朋友或同事下载好的,可以拷贝一份,文件路径 ~/.cocoaPods
pod search AFNetworking
执行结果:
kevindeMacBook-Air:~ kevin$ pod search AFNetworking
Setting up CocoaPods master repo # 我第一次ctrl+c中断过一次,这次下载失败了
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into 'master'...
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF

kevindeMacBook-Air:~ kevin$ pod search AFNetworking # 重新输入该命令
Setting up CocoaPods master repo # 我在这里卡了很久等了几个小时

刚开始我还以为卡死了,看其他教程,这一步只需要几秒。可能是改版了,等了n久。如果出现了上面执行结果里的错误,就再次执行该命令。可能跟网络环境有关系,第一次下载失败,再次下载。你可以按Command+t组合键再打开一个终端,输入命令查看安装进度
du -sh ~/.cocoaPods
# 隔一段时间查一次,下载的非常慢
kevindeMacBook-Air:~ kevin$ du -sh ~/.cocoaPods
60K /Users/kevin/.cocoaPods
kevindeMacBook-Air:~ kevin$ du -sh ~/.cocoaPods
168M /Users/kevin/.cocoaPods
kevindeMacBook-Air:~ kevin$ du -sh ~/.cocoaPods
373M /Users/kevin/.cocoaPods
kevindeMacBook-Air:~ kevin$ du -sh ~/.cocoaPods
965M /Users/kevin/.cocoaPods
kevindeMacBook-Air:~ kevin$
安装完成后出现了一个错误,搜索时出现问题:
kevindeMacBook-Air:~ kevin$ pod search AFNetworking
[!] Unable to find a pod with name, author, summary, or description matching `AFNetworking`
解决方法: 输入下面两条命令,再次查找,等一会就OK了。如果遇到问题可参见: CocoaPods: pod search 搜索类库失败的解决办法
pod setup
rm ~/Library/Caches/CocoaPods/search_index.json
pod search AFNetworking
Creating search index for spec repo 'master'.. Done! # 需要等一会,搜索结果如下
- search可以用了之后就开始正式准备导入Xcode项目了
cd /Users/kevin/Desktop/Projects/BaiSi # 进入项目目录
ls # 查看是否是正确的目录
BaiSi BaiSi.xcodeproj BaiSiTests BaiSiUITests
touch podfile # 创建podfile文件
open podfile #打开文件
# 输入如下内容: (BaiSi为项目名,第二行为sreach里搜到的内容)
target 'BaiSi' do
pod 'AFNetworking', '~> 3.1.0'
end
pod install # 安装,成功后的界面如下图
- 进入工程目录,打开新生成的BaiSi.xcworkspace文件,进入工程,就可以使用AFNetworking框架了
