local notification "didReceiveLocalNotification" calls twice

Question

I am handling local notifications using:

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif

And to schedule a local notification:

- (void)scheduleNotificationWithInterval:(int)minutesBefore {
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    if (localNotif == nil)
        return;

    NSDate *fireDate = [NSDate date];
    localNotif.fireDate = [fireDate dateByAddingTimeInterval:minutesBefore*60];
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.repeatInterval = kCFCalendarUnitMinute;
    localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(@"LocalEvent notification in %i minutes.", nil),minutesBefore];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil);
    localNotif.applicationIconBadgeNumber = 1;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"This is dict, you can pass info for your notification",@"info",nil];
    localNotif.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

    [localNotif release];
    NSLog(@"Event scheduled");
}

When I receive a notification, didReceiveLocalNotification: is called twice.

Am I doing something wrong?

Please help.

Thanks.

Answer 1

I think there is a known bug in the simulator, that fires the delegate notification method twice. It should not happen on the device, tethered to XCode or not.

Answer 2

i was also facing the same problem and the solution which i find is that write this code in didReceiveLocalNotification

if (state == UIApplicationStateActive) {
    NSLog(@"UIApplicationStateActive"); 
}
else if(state == UIApplicationStateInactive){
    NSLog(@"UIApplicationStateInActive");
}

here in these condition i just write the code which i want my application to do on notification , in Active mode and in inactive mode
