XMPP聊天未显示给其他用户结束

Question

在我的项目中实施Xmpp Chat。当我从一个（X-User）用户发送消息时，消息发送成功并显示在用户（X用户）屏幕上。但是其他（Y-User）用户屏幕上未显示消息。当其他用户发送消息时，它也没有显示在他自己的屏幕上。但它显示在（X用户）屏幕上。这意味着消息发送＆amp;删除工作正常。但是消息没有显示在另一端` - （void）sendMessage {

if(![self appDelegate].isXmppConnected)
{
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Message" message:@"Not Connected" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];
    [alert show];
    return;
}

if (![[messageTextView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] length]) {
    [CommonMethods showAlertWithTitle:@"Message" withMessage:@"Please enter text"];
    return;
}
NSString *messageStr = nil;
//        messageStr =  [[textView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] stringByEncodingHTMLEntities];
NSMutableDictionary *dict =  [[NSMutableDictionary alloc]init];
[dict setObject:[messageTextView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] forKey:@"text"];
[dict setObject:@"text" forKey:@"type"];


NSString *jsonString = [dict JSONRepresentation];

messageStr =  [jsonString stringByEncodingHTMLEntities];
messageTextView.text = @"";

//[messageTextView refreshHeight];
NSString *messageID = [[[self appDelegate] xmppStream] generateUUID];

if([messageStr length] > 0)
{
    NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
    [body setStringValue:messageStr];

    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:self.mJabberIDString];
    [message addAttributeWithName:@"id" stringValue:messageID];
    [message addChild:body];
    XMPPMessage * xMessage = [XMPPMessage messageFromElement:message];
    [xMessage addPausedChatState];

    XMPPElementReceipt *receipt;
    [[self appDelegate].xmppStream sendElement:xMessage andGetReceipt:&receipt];
    self.sendChatState = true;

    if ([receipt wait:-1])
    {
        NSLog(@"maraChat - sendMessage - messageSent");
       [self.chatTableView reloadData];
    }
    else
    {
        NSLog(@"maraChat - sendMessage - Failed *********** ");
        [self saveMessageDatabaseForMessageFailToSent:messageStr];
    }
}

}

以上发送消息的代码
