The UIBackgroundModes key identifies which background tasks your application supports. Its value is an array that contains one or more strings with the following values:

• audio – The application plays audible content to the user while in the background.
• location – The application keeps users informed of their location, even while running in the background.
• voip – The application provides the ability for the user to make phone calls using an Internet connection.

You can edit the Info.plist file on Xcode. To add a new key, click on the + sign and write "UIBackgroundModes" as the key, make sure the type is set to string and then in value write audio, location or voip depending on your needs:

This will only work on iOS 4.0 or greater.
