ios afnetworking（iosafnetworking原理）

1.首先通过第三方:CocoaPods下载AFNetworking

1.1.先找到要查找的三方库:pod search + AFNetworking

1.2.出来一堆列表页面,选择三方库最新版本命令,例如: pod ‘MBProgressHUD','~>0.8' (:q 返回)

1.3.创建工程,进入工程: cd + 工程路径

1.4.编辑工程的Podfile文件: vim Podfile

1.5.(platform :iOS, ‘8.0' target “工程名” do pod ‘AFNetworking', ‘~> 3.1.0' end)新版本 (编辑键i)->(Esc键: 输入:wq返回)

1.6.6.保存Podfile的设置,然后进行更新下载三方库: pod update

2.进入工程进行相关操作
