If I understood your question correctly... do you mean after the user hits the Home button?

If so, then I believe it is not possible to do what you want to do.

From apple docs the iOS application can become active in the background to do one or more of the following:

1. Task completion: when the app starts a task and the user hit the home button the app can ask to continue doing the task for a limited time in the background then enters the suspended state

2. Location: the app becomes active for limited time when location change is triggered.

3. For playing audio

4. VOIP

Have a look at the multitasking guidelines docs.

Cheers
