IPhone application in the background

Question

Is there a way to launch an audio or pop-up message from a closed iPhone application. Just how to "receive SMS"

Answer 1

I don’t believe that. Apple said that third-party applications cannot run in the background (although some of them do this). This is why there was a big deal about push notifications last summer (since, unfortunately, this is not the case), this will allow the application to send some data from the server and then respond accordingly.

      [localNotif setAlertBody:NSLocalizedString(@"Hello!",nil)];
      [localNotif setAlertAction:NSLocalizedString(@"Hello", nil)];

      [localNotif setFireDate:[[NSDate date] addTimeInterval:(60*60)]];           
      [localNotif setFireDate:[[NSDate date] addTimeInterval:(24*60*60)]];
      [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
      [localNotif release];
