登录、注册、添加好友、好友列表、聊天.

1.下载XMPPFramework、并将下列文件拖入工程中。

2.添加所需框架

3.添加Header Search Paths和Other Linker Flags

1 libxml includes require that the target Header Search Paths contain
2 //   /usr/include/libxml2
3 // and Other Linker Flags contain
4 //   -lxml2

4.祛除警告
CGBitmapContextCreate 在 ios7下变化
详情请访问博客

1 #if __ipHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_6_1
2 int bitmapInfo = kCGBitmapByteOrderDefault | kCGImageAlphaPRemultipliedLast;
3 #else int bitmapInfo = kCGImageAlphaPremultipliedLast; #endif

5.在spark注册账号，注册信息在openfire的ofUser里。
6.开始
