2014-01-24 01:54:47.317 Chat[5670:811b] -[QBChat xmppStream:didSendPresence:] -> Presence: <presence/>

UPDATE 2:

When I enter background, then enter foreground, I will check if chat is logged in. using this condition: 

[QBChat instance].isLoggedIn

(1)If it's logged in, i fetch several tables

(2)if not, I create a session and login again

My Guess: Is it possible that after entering the background for a while, the session has been destroyed, while [QBChat instance].isLoggedIn still returns YES? If this is the case, then how can I test whether I can safely fetch tables?

The screen always turns black within 3 seconds after entering the foreground. I tried both iOS 6/7

Note: The screen goes black, but the app does not crash. because sendPresence timer still ticking every 15 seconds: 

-[QBChat xmppStream:didSendPresence:] -> Presence: <presence/>

UPDATE 3: I just catch a crash

Was it helpful?

Solution

I solved the question by registering push notification in ChatDidLogin instead of user did login delegate method.

the problem is that login use will return success even use has already logged in, which will register push notification twice. However, chat will fail if already logged in.

My app constantly checks whether the server is logged in by 

+ (BOOL)isServerLoggedIn {
    return [QBChat instance].isLoggedIn;
}

if not logged in, I create session with delegate again, which will then log user in upon success, and then log chat in upon success.

Edit: there is a problem with this design:

What if [QBChat instance].isLoggedIn is true but QBUser is not logged in?? How to check whether QBUser is logged in?

OTHER TIPS

You can be separately logged in to Chat and to REST services.

To check if QBUser is logged in - just create a separate variable and set it to YES in delegate:

// QuickBlox queries delegate
- (void)completedWithResult:(Result *)result{

    if(result.success){

        // User Login
        if([result isKindOfClass:QBUUserLogInResult.class]){

            self.userLoggedIn = YES;
        }
    }
}
