QuickBlox : GCDAsyncSocketErrorDomain error - quickblox

Question

I'm trying to Implement chat module in my app. I am successfully done with Login and Register process from Simple Chat Demo into my app. It also returns user array of offline and online users.
Now after successfully log in I am getting below log :-
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}
And I'm not able to receive chat messages into my app.
Any suggestions ?
Edit :-
In my app, when login is done I am sending the login request to QuickBlox API
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];
}
#pragma mark -
#pragma mark QBActionStatusDelegate
// QuickBlox API queries delegate
-(void)completedWithResult:(Result *)result context:(void *)contextInfo
{
// 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]
delegate:self
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];
}
}
Now in AppDelegate :-
- (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];
}

Answer 1

Do you send presence periodically? It need because Chat server must knows is you online or offline.
Look at QuickBlox Chat setup guide, lines
Keep in mind that QuickBlox it's simple XMPP chat, ...
Just write single line
[NSTimer scheduledTimerWithTimeInterval:30 target:[QBChat instance] selector:#selector(sendPresence) userInfo:nil repeats:YES];
Application will send presence every 30 seconds
