Next, double-click Background Modes to add this capability.

Click on the + symbol to add a capability.

Click the project in the Project navigator.

That’s right - the audio background mode is virtually automatic. When activated, the audio background mode tells iOS to continue playing audio even though the app is in the background. The exception is critical task completion, which any app can perform.

Most background modes won’t work unless you enable specific capabilities that indicate that the app wants to run code in the background. Why does the music stop when the app enters the background? Well, a crucial piece is missing! Note: Check out Execution States for Apps on Apple’s UIKit documentation to learn more about the active state and others.

You can use the music for free with atttribution. The starter project includes audio files from, a popular royalty-free music website.

The model observes the player’s currentItem value to provide updates to the view. The app makes use of AVQueuePlayer to queue up songs and play them in sequence.

The first capability you’re going to add is background audio. There are four tabs - one to cover each mode: Then when you switch to a real device, it may not work at all.īefore you can run the project on a physical device, you must set your development team, as shown here:īuild and run the sample project to get a feel for Sleepless, an app that never rests because it does things in the background. In Simulator, the app might appear to run in the background when you forget a step.

Note: For the full effect, you should follow along on a real device. If you’re only interested in some of these modes, feel free to skip around and just play with the modes that interest you. You’re going to add four of the above modes to the sample app – audio, location, background processing and background fetches.

Background processing: Perform longer critical processes.

Remote notitifications: Send and receive remote notifications.

Background fetch: Perform data refreshes.

Acting as a Bluetooth LE accessory: Allow the app to serve Bluetooth LE information to an accessory.

Using Bluetooth LE accessories: Communicate with Bluetooth LE accessories while in the background.

External accessory communication: Communicate via the lightning port with external accessories.

Voice over IP: Send and receive voice over the internet.

Location Updates: Continue to receive location updates when in the background.

Audio, AirPlay, and Picture in Picture: Play audio and video while the app is in the background.

The user interface and core logic are already built.īefore digging in, here’s a quick overview of the basic background modes available in iOS:

Background Fetch: Perform background updates on a schedule determined by iOS.ĭownload the project files at the top or bottom of the tutorial by clicking the Download Materials button.

Complete finite-length critical tasks: Enable the app continue to complete a critical task after moving to the background.

Receive location updates: Enable the app to receive location changes in the background.

Play audio: Allow the app to continue playing audio in the background.

In this background modes tutorial, you’ll learn about four things your apps can do in the background: You could face one of those dreaded App Store rejections if you try to game the system with background modes that operate beyond the scopes of their purposes.

If your task doesn’t fall into one of the permitted categories, backgrounding may not be for you. Your app can run in the background for specific use cases, including: playing audio, updating location and fetching the latest content from a server. iOS restricts the use of background operations to improve user experience and extend battery life. Chris Wagner wrote the original.Īpple started allowing apps to do work in the background in 2010 with the release of iOS 4 and has evolved and improved background modes since then.
