Use of the afnetworking Open Source Library for iOS development

iOS development afnetworking use of open source Libraries 1. Introduction

Common ways to handle network requests

(1) Nsurlconnection/nsurlsession

(2) ASIHTTPRequest early projects are more common, as authors do not update the

(3) Afnetworking recommended for use in projects

(4) Mknetworkkit try it.

2. Configuring and Using 2.1 configurations

Library files are dragged into the project, including header files

#import "AFNetworking.h"
