How to delete or Exit Particular Groupchat using XMPP in iOS

Currently i am making chat application and i required to delete Particular groupchat.

To delete group i tried 2 solutions but are not working.

1st solution i applied as follow :-

xmppRoomStorage = [[XMPPRoomMemoryStorage alloc] init];

XMPPJID *roomJid = [XMPPJID jidWithString:self.strnameofgroup];

_xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:xmppRoomStorage jid:roomJid];

[_xmppRoom removeDelegate:self delegateQueue:dispatch_get_main_queue()];

[_xmppRoom deactivate];

[_xmppRoom leaveRoom];

2nd solution i applied as follow :-

1st fetch all members in the groupchat and then all members left groupchat manually but it also not working.

NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"http://jabber.org/protocol/muc#admin"];

 NSXMLElement *item = [NSXMLElement elementWithName:@"item"];

 [item addAttributeWithName:@"affiliation" stringValue:@"member"];

 [item addAttributeWithName:@"jid" stringValue:@"jid to remove"];

 [query addChild:item];

XMPPIQ *RemoveUser = [[XMPPIQ alloc] initWithType:@"set" to:[XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",dialuser2,kSIPDomain]] elementID:@"some random id" child:query];

  [SharedAppDelegate.xmppStream sendElement:RemoveUser];

So please help me if any solution to delete particular group.

Thank you

What's the configure of your room? Is it a persistent room?

If yes, then the room must be destroyed by the owner.

xmppRoom.destroyRoom()

Otherwise, the room will be automatically deleted if all the members left.
