XMPP iOS客户端实现三：登录、注册

1.创建一个单例模式来管理xmpp的连接和操作

 1 +(XMPPManager *)share

 2 {

 3     static XMPPManager *_share=nil;

 4     static dispatch_once_t onceToken;

 5     dispatch_once(&onceToken, ^{

 6         _share=[[XMPPManager alloc] init];

 7     });

 8     return _share;

 9 }

10 -(id)init

11 {

12     if (self=[super init]) {

13         [self setupStream];

14     }

15     return self;

16 }

17 - (void)setupStream

18 {

19      xmppStream = [[XMPPStream alloc] init];

20 　　　[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

21      [xmppStream setHostName:@"127.0.0.1"];

22      [xmppStream setHostPort:5222];

23 }

 2.登录和注册都需要使用用户名进行连接服务器，

-(void)login

{

    [self connect];

}

-(void)reg

{

    isReg=YES;

    [self connect];

}

- (BOOL)connect

{

    if (xmppStream.isConnected) {

        [self disconnect];

    }

    if (![xmppStream isDisconnected]) {

        return YES;

    }



    if (self.userName == nil) {

        return NO;

    }

    

    [xmppStream setMyJID:[XMPPJID jidWithString:self.userName]];



    NSError *error = nil;

    if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error])

    {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error connecting"

                                                            message:@"See console for error details."

                                                           delegate:nil

                                                  cancelButtonTitle:@"Ok"

                                                  otherButtonTitles:nil];

        [alertView show];



        return NO;

    }

    

    return YES;

}

3.在连接代理中判断是登录还是注册，发送不同命令

//成功连接服务器

- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

}

//连接服务器失败

- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);



}

- (void)xmppStreamDidConnect:(XMPPStream *)sender

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);



    NSError *error = nil;

    if (isReg)

    {

        if (![xmppStream registerWithPassword:self.pwd error:&error])

        {



        }

    }

    else

    {

        if (![xmppStream authenticateWithPassword:self.pwd error:&error])

        {

            



        }

    }

    

}

4.处理登录或注册代理函数

//登录成功

- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    

    [self goOnline];

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"登录成功"

                                                        message:@"登录成功"

                                                       delegate:nil

                                              cancelButtonTitle:@"Ok"

                                              otherButtonTitles:nil];

    [alertView show];

}

//登录失败

- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"密码错误"

                                                        message:@"密码错误"

                                                       delegate:nil

                                              cancelButtonTitle:@"Ok"

                                              otherButtonTitles:nil];

    [alertView show];

   



}

//注册成功

- (void)xmppStreamDidRegister:(XMPPStream *)sender

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"注册成功"

                                                        message:@"注册成功"

                                                       delegate:nil

                                              cancelButtonTitle:@"Ok"

                                              otherButtonTitles:nil];

    [alertView show];

    isReg=NO;

}

//注册失败

- (void)xmppStream:(XMPPStream *)sender didNotRegister:(NSXMLElement *)error

{

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);

    NSLog(@"%@",[[error elementForName:@"error"] stringValue]);

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"注册失败"

                                                        message:@"注册失败"

                                                       delegate:nil

                                              cancelButtonTitle:@"Ok"

                                              otherButtonTitles:nil];

    [alertView show];

     isReg=NO;

}

 

5.登录或注册的用户名必须“username@主机名”这种格式
