Starting count down timer app

In iPhone, under clock, we've count down timer and when timer expires it plays alarm. So, from my app, I want to start the count down timer. 开发者_开发百科So whether my app is running or not, I'll get alarm. Apart from UILocalNotification, is there any solution?

I think I make my comment an answer...

If you want it to work also if your app gets killed, UILocalNotification is your (only) friend.
