How to add buddy/user in group in xmpp iphone? - objective-c

Question

I have wrote this code for creating room. Using this i had created room in openfire.
-(void)createGroup:(NSString*)groupName
{
XMPPRoomCoreDataStorage *rosterstorage = [[XMPPRoomCoreDataStorage alloc] init];
xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:rosterstorage jid:[XMPPJID jidWithString:[NSString stringWithFormat:#"%##conference.%#/%#",groupName,#"server",self.strUsername]] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:[self xmppStream]];
[xmppRoom joinRoomUsingNickname:#"nickname" history:nil];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[self performSelector:#selector(ConfigureNewRoom) withObject:nil afterDelay:5];
}
-(void)ConfigureNewRoom
{
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
}
Now I want to add buddy/users in the group. so how can i do this ? Thanks in advance.

// Using this it is done
XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];
NSString *strJid = [NSString stringWithFormat:#"%##conference.%#/%#",groupname,strHostname,self.strUsername];
self.xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage jid:[XMPPJID jidWithString:strJid] dispatchQueue:dispatch_get_main_queue()];
[self.xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[self.xmppRoom activate:self.xmppStream];
[self.xmppRoom joinRoomUsingNickname:self.strUsername history:nil];
//inviting
NSString *strInvitedUserName = [NSString stringWithFormat:#"%##%#",personName,strHostname];
[self.xmppRoom inviteUser:[XMPPJID jidWithString:strInvitedUserName] withMessage:message];

You can add it to your roster in this way:
[[[self appDelegate] xmppRoster] addUser:[XMPPJID jidWithString:#"userName"] withNickname:[NSString stringWithFormat:#"%# %#", firstName, lastName] groups:[NSArray arrayWithObjects:#"general", nil]];
and check it:
XMPPRosterCoreDataStorage *xmppRosterStorage = [[self appDelegate] xmppRosterStorage];
BOOL knownUser = [xmppRosterStorage userExistsWithJID:[XMPPJID jidWithString:#"userName"] xmppStream:[self xmppStream]];
