iOS XMPP полученное сообщение на экране беседы

Question

Я работаю над проектом на основе XMPP. Я могу отправить сообщение, и оно отображается на экране беседы, но когда я получаю сообщение, оно отображается только в режиме предупреждения, которое невозможно увидеть на экране беседы.

- (void)viewDidLoad { 
[super viewDidLoad]; 
// Do any additional setup after loading the view. 

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(messageReceived:) name:MessageRecivedNotif object:nil]; 

appdelegate=(AppDelegate*)[[UIApplication sharedApplication] delegate]; 
[self getAllMessagesArrayWithOppositeUser:_jid]; 

[[NSNotificationCenter defaultCenter] addObserver:self 
             selector:@selector(keyboardWasShown:) 
              name:UIKeyboardDidShowNotification 
              object:nil];

Где моя ошибка?

Answer 1

вам нужно установить логику в методе uitableviewcellforrowatindexpath как это.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
UITableViewCell *cell = [tblobj dequeueReusableCellWithIdentifier:@"cell"]; 
UILabel *lbl; 
if (cell==nil) 
{ 
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; 

    if([[[data objectAtIndex:indexPath.row]valueForKey:@"type"] isEqualToString:@"2"]) 
    //if (chatLblRight == 1) 
    { 
     lbl = [[UILabel alloc]initWithFrame:CGRectMake(200, 10, 150, 44)]; 
     [lbl setTextColor:[UIColor redColor]]; 
     [cell.contentView addSubview:lbl]; 
    } 


} 
if([[[data objectAtIndex:indexPath.row]valueForKey:@"type"] isEqualToString:@"2"]) 

//if([[[data objectAtIndex:indexPath.row]valueForKey:@"type"] isEqualToString:@"1"]) 
//if (chatLblRight == 1) 
{ 
    lbl.text = [[data objectAtIndex:indexPath.row]valueForKey:@"text"]; 
    chatLblRight = 0; 
    lbl = [[UILabel alloc]initWithFrame:CGRectMake(200, 10, 150, 44)]; 
    [lbl setTextColor:[UIColor redColor]]; 
    [cell.contentView addSubview:lbl]; 

    return cell; 
} 
else 
{ 
    cell.textLabel.text=[[data objectAtIndex:indexPath.row]valueForKey:@"text"]; 
    return cell; 
    } 

} 

, пожалуйста, проверьте этот код один раз.

Answer 2

Пожалуйста, перейдите XMPP пользовательского класса и после уведомления, как этот

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message 
{ 
//parse you xml and create dictionary For eg : sampledict 
NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter]; 
         [notificationCenter postNotificationName:@"updateValue" object:nil userInfo:sampledict]; 

} 

и получать уведомление от своего класса, как с помощью уведомления, как

[[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(receiveUpdatedValues:) 
               name:@"updateValue" 
               object:nil]; 


-(void)receiveUpdatedValues : (NSNotification *)notification 
{ 
NSDictionary *dictinfo=notification.userInfo; 
// here use your info dict to get your message 
} 

Answer 3

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage*)message 
{ 
//in this the (XMPPMessage*)message parameter is xml data 
//parse you xml and create dictionary For eg : sampledict 
} 

Обычно, когда вы получаете ответ от XMPP, он приходит как данные XML. Это вам нужно разобрать и использовать для ваших операций.

А в коде здесь

if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive) 
{ 
    // UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:displayName 
                 message:body 
                 delegate:nil 
               cancelButtonTitle:@"Ok" 
               otherButtonTitles:nil]; 
    // [alertView show]; 
} 
else 
{ 
    // We are not active, so use a local notification instead 
    UILocalNotification *localNotification = [[UILocalNotification alloc] init]; 
    localNotification.alertAction = @"Ok"; 
    localNotification.alertBody = [NSString stringWithFormat:@"From: %@\n\n%@",displayName,body]; 

    [[UIApplication sharedApplication] presentLocalNotificationNow:localNotification]; 
} 

Вы использовали alertview. Поэтому вам нужно скрыть свое предупреждение, чтобы вы не получали предупреждения. Вместо того, чтобы управлять метод наблюдателя, чтобы получить данные и использовать его

-(void)messageReceived:(NSNotification*)notif 
{ 
XMPPMessage *message=(XMPPMessage*)notif.object; 
NSString *body = [[message elementForName:@"body"] stringValue]; 
NSMutableDictionary *dic_recive = [[NSMutableDictionary alloc]init]; 
[dic_recive setObject:body forKey:@"text"]; 
[data addObject:dic_recive]; 
chatLblRight = 1; 
[tblobj reloadData]; 
} 

Я думаю, что это поможет ..
