Thanks in advance.

What you want is a local sound notification. You can go through this tutorial.

Also note that you can not use any sounds not provided within your application. Here is a extract from the docs:

For this property, specify the filename (including extension) of a sound resource in the application’s main bundle or UILocalNotificationDefaultSoundName to request the default system sound.
