There is project which have chat feature which is been done by using PubNub. I had gone through the tutorial provided by PubNub and had integrated the pubnub.framework and CocoaLumberjack in my project. And had added the coded as shown in this tutorial
My questions are:
Do i have to create different channel to chat with the different friends? Or how the channel in the PubNub will work? I want to do only one-one chat. I don't want to implement any group chats. As per my study from using PubNub for multi users chatting every user have their own channel. But in that case how can I load the unread message count or messages when I am offline.
What is the process to install the PubNub server in my backend server? I am using backend as PHP Laravel.
