Use of AFNetworking open source library for IOS development1. Introduction

Common methods for processing network requests

(1) NSURLConnection/NSURLSession

(2) ASIHttpRequest is common in earlier projects, because the author does not update

(3) AFNetworking is recommended for use in projects.

(4) Try MKNetworkKit.

2. Configure and use 2.1 Configuration

Library files are dragged into the project, including header files

# Import "AFNetworking. h"
