XMPP iOS客戶端實現三：登錄、注冊

1.創建一個單例模式來管理xmpp的連接和操作

+(XMPPManager *)share
{
    static XMPPManager *_share=nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _share=[[XMPPManager alloc] init];
    });
    return _share;
}
-(id)init
{
    if (self=[super init]) {
        [self setupStream];
    }
    return self;
}
- (void)setupStream
{
     xmppStream = [[XMPPStream alloc] init];
　　　[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
     [xmppStream setHostName:@"127.0.0.1"];
     [xmppStream setHostPort:5222];
}

 2.登錄和注冊都需要使用用戶名進行連接服務器，

-(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.在連接代理中判斷是登錄還是注冊，發送不同命令

//成功連接服務器
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
//連接服務器失敗
- (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.處理登錄或注冊代理函數

//登錄成功
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    
    [self goOnline];
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"登錄成功"
                                                        message:@"登錄成功"
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
}
//登錄失敗
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"密碼錯誤"
                                                        message:@"密碼錯誤"
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
   

}
//注冊成功
- (void)xmppStreamDidRegister:(XMPPStream *)sender
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"注冊成功"
                                                        message:@"注冊成功"
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
    isReg=NO;
}
//注冊失敗
- (void)xmppStream:(XMPPStream *)sender didNotRegister:(NSXMLElement *)error
{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    NSLog(@"%@",[[error elementForName:@"error"] stringValue]);
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"注冊失敗"
                                                        message:@"注冊失敗"
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
     isReg=NO;
}

 

5.登錄或注冊的用戶名必須“username@主機名”這種格式
