接着上文，现在我们环境都有了，可以写代码了
先导入并配置好xmpp的环境，我们可以用cocoapod配置好当然我们也可以手动配置具体配置，这里不说了
在storyBoard里面建立如下界面，分别是登录控制器和注册控制器
下面我们先实现登录功能
先创建个xmppmanager单例
.m 文件有这些
#import "XMPPManager.h"
typedef NS_ENUM(NSInteger ,connectToServerPurpose) {
ConnectToServerPurposeOfLogin ,
ConnectToServerPurposeOfRegist,

@property(nonatomic, strong) NSString *userName;
/// 密码
@property(nonatomic, strong) NSString *password;
/// 记录所处的状态
@property(nonatomic) connectToServerPurpose connectToServer;
/// 用户名
@property(nonatomic, strong) NSString *registerUserName;
/// 密码
@property(nonatomic, strong) NSString *registerPassword;
@end
static XMPPManager *xmpp = nil ;
@implementation XMPPManager
// 实现登录的方法

// 连接服务器
[self linkServer];
}
// 实现注册的方法
