In iOS, apps can’t do a lot in the background. Apps are only allowed to do limited set of activities so battery life is conserved.
But what if something interesting happens and you wish to let the user know about this, even if they’re not currently using your app?
For example, maybe the user received a new tweet, their favorite team won the game, or their dinner is ready. Since the app isn’t currently running, it cannot check for these events.
Luckily, Apple has provided a solution to this. Instead of your app continuously checking for events or doing work in the background, you can write a server-side component to do this instead.
And when an event of interest occurs, the server-side component can send the app a push notification! There are three things a push notification can do:
Display a short text message
Play a brief sound
Set a number in a badge on the app’s icon
You can combine these however you see fit; for example, play a sound and set the badge but not display a message.
In this 2-part tutorial series, you’ll get to try this out for yourself by making a simple app that uses APNS (Apple push notification service)!
In this first part, you’ll learn how to configure your app to receive push notifications and receive a test message.
This tutorial is for intermediate or advanced iOS developers. If you are still a beginner to iOS, you should check out some of the other tutorials on this site first. Also, it’s highly recommended that you review these two tutorials first (or have equivalent knowledge):
How To Write A Simple PHP/MySQL Web Service for an iOS App
How To Write an iOS App That Uses A Web Service
Without further ado, let’s push through this!
