UILocalNotification not called when is in background - ios

Question

I'm try to fire UILocalNotification when app is in background and is in active state. I use following:
In App Delegate i want to "catch" notification callback by this (it's not called):
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo{
NSLog(#"recieve-old-notif-here");
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
NSLog(#"recieve-old-notif");
}
Here is how i declared local notification:
NSString *strToShow = [NSString stringWithFormat:#"Время вставать"];
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:15];
notification.alertBody = strToShow;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
Please note that i already achieve that task with iOS 10 notifications, but i want to support this feature on older version devices.
So, my delegate methods suppose to call but their does not, why?

Add below code to the didFinishLaunchingWithOptions method in delegate :
ifdef __IPHONE_8_0
//Right, that is the point
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
else
//register to receive notifications
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
endif
and below delegate methods;
#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
//register to receive notifications
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
//handle the actions
if ([identifier isEqualToString:#"declineAction"]){
}
else if ([identifier isEqualToString:#"answerAction"]){
}
}
#endif
