short polling the hereNow?
Neo -
If I understand, you are calling hereNow every 300ms, which is a lot.
Assuming that is the case, you should only call hereNow upon successful subscribe to a channel (in the status callback for PNConnectedCategory).
When you subscribe to a channel(s), subscribe withPresence:true to get the realtime updates for others' join, leave, timeout and state-change.
Not sure what the presenceInterval property would do in the subscribe. I think you are assuming that presence is polling for changes. But it is actually receiving new presence events (in the addListener's presence callback) just like you receive published messages in the message callback. withPresence:true actually just adds an additional channel for each channel you subscribe to. If you subscribe to channel abc then withPresence:true will also add channel abc-pnpres.
Hope that provides some insights.
Cheers
Craig
