However, this is not the best approach for two basic reasons: First, performing endless and repeated requests leads to unnecessary waste of resources without any doubt at all, and that’s critical when talking about mobile devices.

That solution is based on making use of websockets, and it totally erases the couple aforementioned issues.IO library (client) for i OS and how to achieve real-time communication with a server, I decided that our best hit would be to create a chat application as the demo app of this tutorial.Of course, we won’t make everything from scratch, as the point is to focus on the important details only.Just note that even if you get the final project to test the app without getting involved in the implementation at all, the server part is something you have to mandatorily do if you want to see the app running.Additionally, even though I won’t show any server-side code at all in this tutorial, I’ll be talking quite frequently about the server part because in every single step it’s important to make clear what kind of data we are expecting from the server, or what the server is expecting from the app.You can find a couple of interesting topics about websockets here and here, but also feel free to search the web for additional information.

On my part, I’ll give you the big picture in simple words, so you are able to better understand what comes later.

Or what if real-time conversation between users should be supported as an app feature?

A solution would be to let the app ask for new data the server quite frequently, so anything new to be grabbed as soon as possible.

Once that happens, all the connected apps can send messages to that port (outgoing messages), and listen to it for any incoming messages.

And as that’s the default behaviour when connecting to sockets, every connected client to a server will automatically get its messages without any additional request at all.

As a last word though I’d like to say that the server-side part will operate on your own computer (localhost), and I’ll provide you all the details and code you need for doing that.
