group chat room using XMPP in xcode iphone to support multiuser chat

I have implemented the one to one chat using xmpp. But for one to multiple users I tried to pass an array of recipients in "to" parameter,it sends my message to all of them but cant rece开发者_运维百科ive their messages. How can I use isGroupChatMessageWithBody for enabling the one to multiple chat?

isGroupChatMessageWithBody won't work the way you are trying to use it. It is a method that returns a BOOL based on whether or not the message is of type group chat.
