Question

Answer 1

You cannot add background functionality to your app.

The only ways an application can be controlled in the background are via:

• Audio events. Your app registers and audio session and the user can press play/pause, next, and previous on the lock screen, task bar, or remote headphones. Unless you’re doing audio-specific programming, however, you shouldn’t use this.
• Push notifications. Your app receives messages from a remote server via Apple’s APN, triggered by one of your servers – maybe by a website application.
• Sensor listening. It’s possible to have your application process in the background inputs from hardware sensors, such as the accelerometer, compass, or GPS. However, this kills battery life and is discouraged unless it is absolutely necessary.

So to answer your question, no.
