Need a solution to implement xmpp add friends in group chat and sending message to them in once in ios

I'm having difficulties to add friends, sending invitations and also in group chat like sending one message for all using xmpp. i know that I need to use XEP-0045. But I am not succeeded. Can anybody tell me how to do it.

  1. Send friend request for one to one chat.
  2. send invitation to join chat room.
  3. send message to chat room's friends.

if somebody has sample code that would be great..

Thanks in advance


for #3 : send message to chat room's friends.

-(void) sendGroupMessage:(NSString *) groupJID Message:(NSString *)msg{

    XMPPJID *roomJID = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@conference.%@",groupJID,SERVER_URL]];

    XMPPRoom *muc = [[XMPPRoom alloc] initWithRoomStorage:xmppRoomStorage jid:roomJID

    [muc   activate:xmppStream];

    [muc   addDelegate:self delegateQueue:dispatch_get_main_queue()];

    [muc   sendMessageWithBody:msg];


Point 2: Send invitation to join chat room.

You can send invitation to others when you get the response in following delegate (xmppRoomDidCreate):

- (void)xmppRoomDidCreate:(XMPPRoom *)xmppRoom
    [xmppRoom inviteUser:[User JID Here] withMessage:@"Your Message Here"];
    // You can send invitations in loop if you have multiple users to invite

Point 3: Send message to chat room's friends. Actually the message is broadcasted in group. Surely shall be delivered to all members in group.

- (void) sendMessageInGroup:(NSString *) message withGroupName:(NSString *) groupName
    NSString * qualifiedGroupName = [NSString stringWithFormat:@"%@@%@", [groupName lowercaseString], SERVER_NAME];

    //      self.xmppRoomDetails consists of your muc rooms' objects i.i XMPPRoom
    for (int i = 0; i < self.xmppRoomDetails.count; i++)

        XMPPRoom * room = [self.xmppRoomDetails objectAtIndex:i];
        XMPPJID * myRoomJID = room.myRoomJID;
        NSString * roomName = [NSString stringWithFormat:@"%@@%@", [myRoomJID.user lowercaseString], SERVER_NAME];

        if ([qualifiedGroupName rangeOfString:roomName].location != NSNotFound)
            XMPPRoom * sendMessageWithRoom = [self.xmppRoomDetails objectAtIndex:i];
            [sendMessageWithRoom sendMessage:message];
