The number of unread messages from xmpp ios

I am developing a chat application using XMPPFrameWork. Everything works fine, but I'm stuck in getting the number of unread messages. I have to show the   tableViewnumber of posts that are not open yet. How can I continue, have any ideas? I tried to show mostRecentMessage, but it didn’t work. Any help would be appreciated. Thank.

XMPP has an attribute called "unread messages" in "XMPPUserCoreDataStorageObject". Pass the "jid" FROM to get the corresponding user object, and add the value "unreadMessages" below in the Appdelegate application.

 - (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

and update it again in the same db.Like,

XMPPUserCoreDataStorageObject *user = [self.xmppRosterStorage userForJID:[XMPPJID jidWithString:[NSString stringWithFormat:@"%@", [[[message fromStr] componentsSeparatedByString:@"/"]objectAtIndex:0] ]]
                                                                          xmppStream:self.xmppStream
                                                                managedObjectContext:[self managedObjectContext_roster]];

    NSNumber *number = user.unreadMessages;

    int value = [number intValue];

    number = [NSNumber numberWithInt:value + 1];

    user.unreadMessages = number;

Then use the code above in any view manager to get an unread number of messages.
