QuickBlox : GCDAsyncSocketErrorDomain错误

Question

我正在尝试在我的应用程序中实现聊天模块。我已经成功地完成了从Simple Chat Demo到我的应用程序中的Login和Register进程。它还返回脱机和联机用户的用户数组。

现在，在成功登录后，我得到了以下日志:-

error:
2012-12-07 14:50:07.056 App[5324:790b] QBChatService/xmppStreamDidConnect
2012-12-07 14:50:08.285 App[5324:790f] QBChatService/xmppStreamDidAuthenticate
2012-12-07 14:51:08.291 App[5324:711f] QBChatService/xmppStreamDidDisconnect, error=Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo=0xb982330 {NSLocalizedDescription=Socket closed by remote peer}

而且我无法在我的应用程序中接收聊天消息。

有什么建议吗？

编辑:-

在我的应用程序中，登录完成后，我会将登录请求发送到QuickBlox应用程序接口

if(loginDone)
{
     NSString *userName = [_textUsername.text stringByReplacingOccurrencesOfString:@"@" withString:@"_"];
     NSString *userPass = [_textPassword.text stringByReplacingOccurrencesOfString:@"@" withString:@"_"];

     // Authenticate user
     [QBUsers logInWithUserLogin:userName password:userPass delegate:self context:userPass];
}

    // QuickBlox User authentication result
    if([result isKindOfClass:[QBUUserLogInResult class]])
    {
        // Success result
        if(result.success)
        {
            QBUUserLogInResult *res = (QBUUserLogInResult *)result;

            // save current user
            [[DataManager shared] setCurrentUser: res.user];
            NSLog(@"%@",res.user);

            [[[DataManager shared] currentUser] setPassword:(NSString *)contextInfo];
            NSLog(@"%@",res.user);

            // Login to Chat
            [QBChat instance].delegate = self;
            [[QBChat instance] loginWithUser:[[DataManager shared] currentUser]];

            // Register as subscriber for Push Notifications
            [QBMessages TRegisterSubscriptionWithDelegate:nil];

            // send request for getting user's filelist
            PagedRequest *pagedRequest = [[PagedRequest alloc] init];
            [pagedRequest setPerPage:10];

            [QBContent blobsWithPagedRequest:pagedRequest delegate:self];

            [pagedRequest release];
        }
        else
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Errors"
                                                            message:[result.errors description]

                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles: nil];
            alert.tag = 1;
            //[alert show];
            [alert release];

            [HUD hide:YES];
            [self AfterLoginController];
        }
    }
}

-(void)completedWithResult:(Result *)result
{
    if([result isKindOfClass:[QBUUserLogInResult class]]) // QuickBlox User authentication result
    {
        // Success result
        if(result.success)
        {
            // If we are authenticating through Twitter/Facebook - we use token as user's password for Chat module
            [self completedWithResult:result context:[BaseService sharedService].token];
        }
    }
    else if ([result isKindOfClass:[QBCBlobPagedResult class]])
    {
        // Success result
        if(result.success){
            QBCBlobPagedResult *res = (QBCBlobPagedResult *)result;

            // Save user's filelist
            [DataManager shared].fileList = [[res.blobs mutableCopy] autorelease];

            AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
            [app startsendPresenceTimer];

            [HUD hide:YES];            
            [self AfterLoginController];
        }
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Errors"
                                                        message:[result.errors description]
                                                       delegate:self
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles: nil];
        alert.tag = 1;
        //[alert show];
        [alert release];

        [HUD hide:YES];
        [self AfterLoginController];
    }
}

现在在AppDelegate中：

- (void) startsendPresenceTimer
{
    [QBChat instance].delegate = self;

    // send presence
    if(self.sendPresenceTimer == nil)
    {
        self.sendPresenceTimer = [NSTimer scheduledTimerWithTimeInterval:10 target:self selector:@selector(sendPresence) userInfo:nil
                                                                 repeats:YES];
    }

    if (self.requesAllUsersTimer == nil)
    {
        self.requesAllUsersTimer= [NSTimer scheduledTimerWithTimeInterval:10 target:self selector:@selector(updateUsers) userInfo:nil repeats:YES];
    }
    [self.requesAllUsersTimer fire];
}

// send presence
- (void)sendPresence{
    // presence in QuickBlox Chat
    [[QBChat instance] sendPresence];
    // presence in QuickBlox
    [QBUsers userWithExternalID:1 delegate:nil];
}

- (void)updateUsers
{
    // Retrieve all users
    PagedRequest* request = [[PagedRequest alloc] init];
    request.perPage = 100; // 100 users
    [QBUsers usersWithPagedRequest:request delegate:self];
    [request release];
}

您是否定期发送在线状态？它之所以需要，是因为聊天服务器必须知道你是在线还是离线。

看看QuickBlox Chat setup guide，lines

记住，QuickBlox是简单的XMPP聊天，...

只写一行

[NSTimer scheduledTimerWithTimeInterval:30 target:[QBChat instance] selector:@selector(sendPresence) userInfo:nil repeats:YES];

应用程序将每30秒发送一次状态
