XMPP登录注册1

1. 环境准备：openfire + mysql 5.1.6 + Xcode5 + XMPP.Framework （至于环境的配置， 请自己百度， 推荐: http://www.cnblogs.com/xiaodao/archive/2013/04/05/3000554.html） 

2. cocoapods 

platform :ios, '7.0'
pod "XMPPFramework", "~>3.6.4"

3.工程： ARC + COREDATA + XIB(Storyboard)

4.直奔重点：  XMPP工具单例

　　1. 首先， 创建一个Infromation.h 文件 用来存放我们需要的一些基本信息，比如host之类的。  然后把这个头文件导入pch文件中 注意我的Domains 后边多一个@

#ifndef ADXMPP_BE_Information_h
#define ADXMPP_BE_Information_h

#define SERVER @"127.0.0.1"
#define DOMAINS @"@127.0.0.1"

#endif

　　2. 创建ADXMPPConn 类、 开始编辑我们的XMPP连接、 登录、 注册核心代码
