In my iPhone app I would like to run several queries when the
application is in background.
I already use ASIHttpRequest to make the queries, that works fine but
now I try to find a way to trigger them in background.
In the app delegate, I have added a call to the method making the request:

   [self getItemsFromServer]

getItemsFromServer runs an asynchronous request (on the simulator I
saw the log of this methods once I get back the application to the
foreground).
How can I use some kind of timer to have this method ran every 10
minutes (I just need to run it 4 or 5 times, not each 10 minutes until
it goes back to foreground 🙂 )?

thanks a lot,

Best Regards,

Luc

    iOS4 allows your app to run for X amount of time, granted that iOS4 grants you the time you request. Check out: Completing a Long-Running Task in the Background.

    Specifically,

    Any time before it is suspended, an application can call the beginBackgroundTaskWithExpirationHandler: method to ask the system for extra time to complete some long-running task in the background. If the request is granted, and if the application goes into the background while the task is in progress, the system lets the application run for an additional amount of time instead of suspending it
