XMPP iOS: unable to connect openfire server

Question

I develop the iOS XMPP app with the tutorial in this link >>> http://code.tutsplus.com/tutorials/building-a-jabber-client-for-ios-xmpp-setup--mobile-7190

And now I run my project it is not connecting to my openfire server but there are no errors displaying. I heard some developers they had solve relevant problem by "enabling" SSL certificate in iOS client in this link >>> Unable to connect openfire server using ios client . Do I have to enable it? and how to enable it?

This problem had takes me a week so I decided to post on stackoverflow.

here is my "JabberClientAppDelegate.m"

         abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. 

         Typical reasons for an error here include:
         * The persistent store is not accessible;
         * The schema for the persistent store is incompatible with current managed object model.
         Check the error message to determine what the actual problem was.


         If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.

         If you encounter schema incompatibility errors during development, you can reduce their frequency by:
         * Simply deleting the existing store:
         [[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]

         * Performing automatic lightweight migration by passing the following dictionary as the options parameter:
         @{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES}

         Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.

I am sorry if there are too much codes to review, I am a beginner of iOS development and XMPP, please kindly review my mistake and guide me how to fix I'll be truly appreciate, thank you.

You forget to set port number and host name of server.

Try this.

- (BOOL)connect {

        [self setupStream];

    // set openfire server host name and port number to connect 
    [self.xmppStream setHostName:@"serverHostName"];
    [self.xmppStream setHostPort:@"serverPortNumber"];

        NSString *jabberID = [[NSUserDefaults standardUserDefaults] stringForKey:@"userID"];
        NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];

        if (![xmppStream isDisconnected]) {
            return YES;
        }

        if (jabberID == nil || myPassword == nil) {

            return NO;
        }


        [xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
        password = myPassword;

        NSError *error = nil;
        if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]){
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                message:[NSString stringWithFormat:@"Can't connect to server %@", nil]
                                                               delegate:nil
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil];
            [alertView show];

            return NO;
        }



        return YES;
    }
