ios - 使用 XMPP 从 OpenFire 获取所有用户名

Question

在我的应用程序中，我需要从 OpenFire 获取All the UserName。

我使用了下面的代码，但它没有提供 nil 数据。

我觉得我的 didReceiveIQ 方法有问题，但第一次使用 XMPP，所以没有得到实际问题。

我获取数据的代码是

- (void)getAllRegisteredUsers {

NSError *error = [[NSError alloc] init];
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='http://jabber.org/protocol/disco#items' node='all users'/>"
                                                        error:&error];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get"
                             to:[XMPPJID jidWithString:[NSString stringWithFormat:@"Domain Name with jid"]]
                      elementID:[xmppStream generateUUID] child:query];
[xmppStream sendElement:iq];
}  

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"http://jabber.org/protocol/disco#items"];

NSLog(@"queryelement %@",queryElement);

if (queryElement) {

    NSLog(@"query in if");
    NSArray *itemElements = [queryElement elementsForName: @"item"];
    NSMutableArray *mArray = [[NSMutableArray alloc] init];
    for (int i=0; i<[itemElements count]; i++) {

        NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
        [mArray addObject:jid];

        NSLog(@"User in OpenFire = %@",jid);

    }

    NSLog(@"mArray = %@",mArray);

}

return NO;
}  

感谢任何形式的帮助....

我正在努力让所有注册用户从 openfire 进入我的应用程序。我尝试了上述所有方法，但没有帮助我!尝试了很多之后，我得到了一个解决方案来获取所有注册用户......这是代码:

- (void)getAllRegisteredUsers {

    NSError *error = [[NSError alloc] init];
    NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='jabber:iq:roster'/>" error:&error];
    XMPPIQ *iq = [DDXMLElement elementWithName:@"iq"];
    [iq addAttributeWithName:@"type" stringValue:@"get"];
    [iq addAttributeWithName:@"none" stringValue:@"ANY_ID_NAME"];
    [iq addAttributeWithName:@"both" stringValue:@"ANY_ID_NAME"];
    [iq addChild:query];
    [xmppStream sendElement:iq];
}

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{

    NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"jabber:iq:roster"];

    if (queryElement) {
        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++) {

            NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            [mArray addObject:jid];
        }
        NSLog(@"%@",mArray);
    }
    return YES;
}

这对我有用，希望对其他人也有用...:)
