AFNetworking了解-阿里云开发者社区

AFNetworking是一个讨人喜欢的网络库,适用于iOS以及Mac OS X. 它构建于在NSURLConnection, NSOperation, 以及其他熟悉的Foundation技术之上. 它拥有良好的架构,丰富的api,以及模块化构建方式,使得使用起来非常轻松.例如,他可以使用很轻松的方式从一个url来得到json数据:

综述

CORE:

AFURLConnectionOperation:一个 NSOperation 实现了NSURLConnection 的代理方法.

HTTP Requests:

AFHTTPRequestOperation:AFURLConnectionOperation的子类,当request使用的协议为HTTP和HTTPS时,它压缩了用于决定request是否成功的状态码和内容类型.

AFJSONRequestOperation:AFHTTPRequestOperation的一个子类,用于下载和处理jason response数据.

AFXMLRequestOperation:AFHTTPRequestOperation的一个子类,用于下载和处理xml response数据.

AFPropertyListRequestOperation:AFHTTPRequestOperation的一个子类,用于下载和处理property list response数据.

HTTP CLIENT:

AFHTTPClient:捕获一个基于http协议的网络应用程序的公共交流模式.包含:

使用基本的url相关路径来只做request
为request自动添加设置http headers.
使用http 基础证书或者OAuth来验证request
为由client制作的requests管理一个NSOperationQueue
从NSDictionary生成一个查询字符串或http bodies.
从request中构建多部件
自动的解析http response数据为相应的表现数据
在网络可达性测试用监控和响应变化.

IMAGES

AFImageRequestOperation:一个AFHTTPRequestOperation的子类,用于下载和处理图片.

UIImageView+AFNetworking:添加一些方法到UIImageView中,为了从一个URL中异步加载远程图片
