即时通讯2

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
- (void)linkServer
