I have integrated PubNub for my iOS app. In this I have to subscribe the channel when I enter into the chat view and unsubscribe when I get back from chat view. I am trying to subscribe a channel, but its taking delay to subscribe like 2 - 4 seconds. And same issue for unsubscribe. Its bit difficult for me to implement it in my app. I have checked the lot of links given by PubNub, but still getting the issue. Can you please suggest me, how to subscribe and unsubscribe a channel in my app scenario?
It sound like you are talking about UI speed? Is there a delay in transitioning between chat views? It seems slow to change the view?
