"unavailable"(Offline) presence not updating at the both end

Question

i used - (void)blockJID:(XMPPJID*)xmppJID method in XMPPBlocking class

<iq from='[email protected]/chamber' type='set' id='block1'>
      <block xmlns='urn:xmpp:blocking'>
         <item jid='[email protected]'/>
      </block>
    </iq>

I want to block user(s) in a xmpp application (like whatsapp). when i use the above code, "unavailable" presence not updating at the both end. but after re-connecting, it updating "unavailable" presence at the both end.

when i block user, my requirements are,

• user should not receive messages at both end (it works perfectly not even reconnected)
• both user should be "unavailable" (the other end not receiving anything when i execute above IQ, So working only after reconnected)

How can i notify offline presence each other after blocking? How can i achieve this in proper way?

Answer 1

Finally i done with.

For notify buddy(other end user) used below code,

XMPPPresence *presence = [[XMPPPresence alloc] initWithType:@"unavailable" to:jid]; 
[_xmppStream sendElement:presence];

And buddy's presence updated locally in sender side.

For unblock case, i just subscribe buddy(other end user) again.

I don't know whether its correct way. i always waiting for perfect solutions from you all.
