XMPPFramework - How to create a MUC room and invite users?

Question

I am using Robbiehanson's iOS XMPPFramework. I am trying to create a MUC room and invite a user to the group chat room but it is not working.

I am using the following code:

XMPPRoom *room = [[XMPPRoom alloc] initWithRoomName:@"user101@conference.jabber.org/room" nickName:@"room"];
[room createOrJoinRoom];
[room sendInstantRoomConfig];
[room setInvitedUser:@"ABC@jabber.org"];
[room activate:[self xmppStream]];    
[room inviteUser:jid1 withMessage:@"hello please join."];
[room sendMessage:@"HELLO"];

The user ABC@jabber.org should receive the invite message but nothing is happening.

Any help will be appreciated. :)

After exploring various solutions, I've decided to compile and share my implementation here:

Create an XMPP Room:

XMPPRoomMemoryStorage *roomStorage = [[XMPPRoomMemoryStorage alloc] init];

/** 
 * Remember to add 'conference' in your JID like this:
 * e.g. uniqueRoomJID@conference.yourserverdomain
 */

XMPPJID *roomJID = [XMPPJID jidWithString:@"chat@conference.shakespeare"];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomStorage
                                                       jid:roomJID
                                             dispatchQueue:dispatch_get_main_queue()];

[xmppRoom activate:[self appDelegate].xmppStream];
[xmppRoom addDelegate:self 
        delegateQueue:dispatch_get_main_queue()];

[xmppRoom joinRoomUsingNickname:[self appDelegate].xmppStream.myJID.user 
                        history:nil 
                       password:nil];

Check if room is successfully created in this delegate:
```
- (void)xmppRoomDidCreate:(XMPPRoom *)sender
```
Check if you've joined the room in this delegate:
```
- (void)xmppRoomDidJoin:(XMPPRoom *)sender
```

After room is created, fetch room configuration form:

- (void)xmppRoomDidJoin:(XMPPRoom *)sender {
    [sender fetchConfigurationForm];
}

Configure your room

/**
 * Necessary to prevent this message: 
 * "This room is locked from entry until configuration is confirmed."
 */

- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm 
{
    NSXMLElement *newConfig = [configForm copy];
    NSArray *fields = [newConfig elementsForName:@"field"];

    for (NSXMLElement *field in fields) 
    {
        NSString *var = [field attributeStringValueForName:@"var"];
        // Make Room Persistent
        if ([var isEqualToString:@"muc#roomconfig_persistentroom"]) {
            [field removeChildAtIndex:0];
            [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
        }
    }

    [sender configureRoomUsingOptions:newConfig];
}

Invite users

- (void)xmppRoomDidJoin:(XMPPRoom *)sender 
{
    /** 
     * You can read from an array containing participants in a for-loop 
     * and send multiple invites in the same way here
     */

    [sender inviteUser:[XMPPJID jidWithString:@"keithoys"] withMessage:@"Greetings!"];
}

There, you've created a XMPP multi-user/group chat room, and invited a user. :)

@rohitmandiwal My pleasure! You can make a password-protected MUC room via this line as seen above - `[xmppRoom joinRoomUsingNickname:[self appDelegate].xmppStream.myJID.user history:nil password:@"myPassword"];` – Keith OYS Jul 27 '14 at 16:21
Hello All, Thanks you all and starckoverflow, I am able to create group and send Invitations to other with Both Storage (Core data & Memory Storage). Issue is when I create Second group it removes first group data from Core data storage and Also How can we auto join other user ? – Mangesh Oct 03 '14 at 14:32
@KeithOYS - thanks so much for this code. I am unable to understand the step 3 where the user is joining the room. How do I get to know that the user has joined the room or not. Also if you could help us understand how do we receive and send messages once we have implemented this. Thanks a lot in advance for your help. – Daljeet Feb 24 '15 at 18:37

Check the latest XMPPMUCLight & XMPPRoomLight its similar to Whatsapp and other today's trends social app rooms that don't get destroyed or members kicked when offline or no one in room.

Refer this documentation & mod from MongooseIM

I have the feeling that the first thing to do after alloc-init is to attach it to your xmppStream, so it can use xmppStream to send/receive messages.

More exactly:

XMPPRoom *room = [[XMPPRoom alloc] initWithRoomName:@"user101@conference.jabber.org/room" nickName:@"room"];
[room activate:[self xmppStream]];

//other things (create/config/...)
