XMPPFramework初始化、登录、注册详解（附代码）

刚开始接触XMPP的时候，由于下载的库有问题，后期做起来很困难，在这里我推荐给大家的库：github：https://github.com/robbiehanson/XMPPFramework

本人做的项目demo：https://github.com/humengchi/test.git

第一步、添加依赖

> 拷贝 <XMPPFramework>/Vendor/CocoaLumberjack 到项目根目录下，add files...，选择 CocoaLumberjack 文件夹

> 同样的步骤，拷贝 CocoaAsyncSocket 和 KissXML 并添加到项目中

CocoaAsyncSocket 依赖 CFNetwork.framework 和 Security.framework，在 TARGETS -> Build Phases -> Link Binary With Libraries 添加

KissXML 使用了 libxml2 解析 XML，所以

首先，我们需要在 TARGETS -> Build Phases -> Link Binary With Libraries 添加 libXML2.dylib

然后，在 TARGETS -> Build Settings -> Other Linker Flags 添加 -lxml2，TARGETS -> Build Settings -> Header Search Paths 添加 /usr/include/libxml2

> 拷贝 <XMPPFramework>/Vendor/libidn 到项目根目录下，添加静态库文件 libidn.a 和头文件 idn-int.h 和 stringprep.h

 

第二步、添加 XMPPFramework

拷贝源码目录下的 Authentication Categories Core 和 Utilities 到项目根目录下并添加到项目中

此外，需要添加动态连接库 libresolv.dylib ，在 TARGETS -> Build Phases -> Link Binary With Libraries 添加

第三步、代码详解
