I have a small application which is much like a clock. It has been working great on IOS3, but now I am updating it to iOS4.
What I want to do in iOS4 is to let it play a sound any giving time. For instance, if I set it to play at 4.00 PM I want it to play a sound, a sound from the application not from the OS. This works if the app is launced, but if the user went back to the home screen I want the same to happen.
It is OK if a UIAlertView pops up istead of the application.
How can I do this?
Best regards,

Sounds like you’ll need to use a local notification:
