is there any option in iphone so that i can start my application automatically within a predefined time interval ? For example like alarm application but we don't want our application to run in the background. thanks in advance.
There is not option like this. The best you can implement is local notification which is displayed to the user and then application can be launch via the notification.
Check out About Local Notifications and Push Notifications to know how it works and eventually implement it
No. There is no way to start your application automatically.
You can give user option to start your application using Local notification though it does not guarantee your application would be started because if user ignores local notification than your application will not launched.
There is no officially supported way to do this.

I have an idea for a unique alarm application on the iPhone. But at the moment the only way I can see of initiating the alarm is by leaving the app running all night getting it to poll for the current time. Is there anyway to make an app "wake up" or initiate at a certain time. I know I can use push or local notifications but they require user input before loading my app. Thinking about it I could leave my app on all night, but literally doing nothing (saving battery if not being charged) and then subscribe to a local notification for the alarm itself.
Alternatively, can I make the iPhone run my app when an alarm sounds so I don't have to deal with alarm settings at all?
No, your only option is to use either Local or Push notifications.
I think using event kit framework add event in default iPhone calender.
I need my app to set the alarm. how can it be done without using Local Notifications as it will not work in IOS 3.0 . Please help..
Thanks in advance.
You can't. Apps pre-multiasking had to be running in the foreground all the time in order to achieve something like this.
If you have a server, then you can implement it through Apple's Push Notifications. Set the alarm by storing an entry in the server, and when it rings, have the server send the push notification. Otherwise you cannot do this without jailbreaking the phone.
I was wondering if it was possible to have an "alarm" style app that would run at a certain time? Would the application have to be run and then left open?
I know with multi-tasking on the iPhone 4 a user could open the app and run it in the background. If my original question isn't possible, is it possible to bring an app running in the background back into the foreground after a certain time?
Thank you very much for your help.
Have a look at the new 4.0 feature called Local Notifications. Local and Push Notification Programming Guide
You can use EventKit to put certain alarms. It is however not possible to schedule to launch of your app. You can not bring your app forward like you suggest. You could however send a push notification. The link suggested by Jessedc gives a lot of in-depth information about the use of this.
I am trying to create a iPhone App which gets invoked automatically at a particular interval.

You can't. (At least, not on non-jailbroken phones.) Best you can do is send the user a push notification, and give them the option of running your app in response.
I'm developing a todo list application. I'm looking for any way to alert the user when a task becomes due, even if the app is not running. Is there any way to set the program to run at a specified time w/out user interaction? Or a way to bring up an alert anyway?
Edit: How can I add an item to the calendar?
No, not until the push notification service gets released.
Your best bet right now is allowing users to add reminders to the Calendar - without the push service, there's no notifications without your app running actively.
As has been made very clear by Steve Jobs himself, the iPhone SDK will NOT support background processes. In addition, there is no API to access the calendar on the iPhone.
If these things are important to you, you should file an enhancement request:
Apple Bug Reporter
But even once push is released, that won't enable you to have the application independently alert the user. You would have to run a server that would push notifications to people once a task is approaching due, which means you would have to have everyone's task list synced to your server.
