Answer 1

- (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:@"DOMAIN"]
                      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"];

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];
    }
}

Hi Guys finally i found the alternative answer for this by searching users using their username.

1.for every contact i am adding emailid username@domainname like this.
2.in the place searchstring if we use domainname then we will get all registered users.

//Request
- (void)getDetailsofRegisteredUser {

    //To Search Peticular User either by using their name, email or username
    NSString *userBare1  = [[[[self appDelegate] xmppStream] myJID] bare];
    NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
    [query addAttributeWithName:@"xmlns" stringValue:@"jabber:iq:search"];

    NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:@"jabber:x:data"];
    [x addAttributeWithName:@"type" stringValue:@"submit"];

    NSXMLElement *formType = [NSXMLElement elementWithName:@"field"];
    [formType addAttributeWithName:@"type" stringValue:@"hidden"];
    [formType addAttributeWithName:@"var" stringValue:@"FORM_TYPE"];
    [formType addChild:[NSXMLElement elementWithName:@"value" stringValue:@"jabber:iq:search" ]];

    NSXMLElement *userName = [NSXMLElement elementWithName:@"field"];
    [userName addAttributeWithName:@"var" stringValue:@"Username"];
    [userName addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1" ]];

    NSXMLElement *name = [NSXMLElement elementWithName:@"field"];
    [name addAttributeWithName:@"var" stringValue:@"Name"];
    [name addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];

    NSXMLElement *email = [NSXMLElement elementWithName:@"field"];
    [email addAttributeWithName:@"var" stringValue:@"Email"];
    [email addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];

    //Here in the place of SearchString we have to provide registered user name or emailid or username(if it matches in Server it provide registered user details otherwise Server provides response as empty)
    NSXMLElement *search = [NSXMLElement elementWithName:@"field"];
    [search addAttributeWithName:@"var" stringValue:@"search"];
    [search addChild:[NSXMLElement elementWithName:@"value" stringValue:[NSString stringWithFormat:@"%@", SearchString]]];

    [x addChild:formType];
    [x addChild:userName];
    [x addChild:name];
    [x addChild:email];
    [x addChild:search];
    [query addChild:x];

    NSXMLElement *iq = [NSXMLElement elementWithName:@"iq"];
    [iq addAttributeWithName:@"type" stringValue:@"set"];
    [iq addAttributeWithName:@"id" stringValue:@"searchByUserName"];
    [iq addAttributeWithName:@"to" stringValue:[NSString stringWithFormat:@"search.%@",DOMAIN_NAME]];
    [iq addAttributeWithName:@"from" stringValue:userBare1];
    [iq addChild:query];
    [[[self appDelegate] xmppStream] sendElement:iq];

}

//We will get response here

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

    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    NSLog(@"searched format %@", iq);

}
