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,
};
@interface XMPPManager ()<XMPPStreamDelegate>
/// 用户名
@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
- (void)loginWithUserName:(NSString *)name password:(NSString *)password
{
self.userName = name;
self.password = password;
// 记录登录状态
self.connectToServer = ConnectToServerPurposeOfLogin;
// 连接服务器
[self linkServer];
}
// 实现注册的方法
- (void)registWithUserName:(NSString *)name password:(NSString *)password
{
self.registerUserName = name;
self.registerPassword = password;
// 记住注册状态
self.connectToServer = ConnectToServerPurposeOfRegist;
//连接服务器
[self linkServer];
}
// 连接服务器

break;

break;

}
// 要连接服务器,要有用户的身份认证
// 身份证
// 参数一: 用户名
// 参数二: 域名
// 参数三: 资源
XMPPJID *jid = [XMPPJID jidWithUser:string domain: kDomin resource:kResource];
// 在通道上进行身份验证
self.xmppStream.myJID = jid;
// 如果当前聊天工具处于连接状态或者已经连接状态,此时,你需要切断连接(此逻辑不唯一)
