xcode - ios local notification check before fire -

i trying run function every n-minutes when app not running. thing local notification suitable that, have 1 problem.

if set local notification :

 -(void)notification{      uilocalnotification *localnotif = [[uilocalnotification alloc] init];      if (localnotif == nil)          return;      localnotif.firedate = [[nsdate date] datebyaddingtimeinterval:15];      //localnotif.timezone = [nstimezone defaulttimezone];   // notification details      localnotif.alertbody = @"marko";  // set action button      localnotif.alertaction = @"view";       localnotif.soundname = uilocalnotificationdefaultsoundname;      localnotif.applicationiconbadgenumber = 1;   // specify custom data notification      nsdictionary *infodict = [nsdictionary dictionarywithobject:@"somevalue" forkey:@"somekey"];      localnotif.userinfo = infodict;  // schedule notification    [[uiapplication sharedapplication] schedulelocalnotification:localnotif]; } 

the notification fired every time , do:

 - (void)application:(uiapplication *)app didreceivelocalnotification:(uilocalnotification *)notif { nslog(@"recieved notification %@",notif);  } 

what want after 15s first fire function , if function return yes play sound , put badge on it.

how that?

if application foremost , visible when system delivers notification, no alert shown, no icon badged, , no sound played. however, application:didreceivelocalnotification: called if application delegate implements it.

make sure testing in device.
