Comment définir la Notification Locale intervalle de répétition à la coutume de l'intervalle de temps?

Eu la réponse, c'est aussi droit qu'il obtient.

Vous ne pouvez pas créer des intervalles de répétition.

Vous avez à utiliser sur NSCalendarUnit dans la construction des Intervalles de Temps.

J'ai essayé toutes les solutions ci-dessus et même essayé d'autres animaux, mais aucun d'entre eux travaillaient.

J'ai investi suffisamment de temps pour trouver qu'il n'y a aucun moyen que nous pouvons faire fonctionner personnalisé intervalles de temps.

J'ai une idée de comment faire cela, j'ai mis en place dans mon projet

Tout d'abord, créer de notification locale avec le feu de la date (par exemple, toutes les minutes).
Prochaine étape: remplir les infos de l'utilisateur avec l'id unique pour cette notification (si vous souhaitez supprimer à l'avenir) et personnalisé de votre période comme ceci:

-(void) createLocalRepeatedNotificationWithId: (NSString*) Id
{

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    NSTimeInterval your_custom_fire_interval = 60; //interval in seconds
    NSDate *remindDate = [[NSDate date] dateByAddingTimeInterval:your_custom_fire_interval];
    localNotification.fireDate = remindDate;
    localNotification.userInfo = @{@"uid":Id, @"period": [NSNumber numberWithInteger:your_custom_fire_interval]};
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

Après cela, mettre en œuvre -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification dans votre AppDelegate:

1. Chercher votre propre période de infos de l'utilisateur.
2. Changement d'incendie date de la prochaine période de

3. Il suffit de l'ajouter dans le sheluded notificatiots de nouveau!

   NSInteger period = [[notification.userInfo objectForKey:@"period"] integerValue]; //1
   NSTimeInterval t= 10 * period;
   notification.fireDate =[[NSDate date] dateByAddingTimeInterval:t]; //2 
    [[UIApplication sharedApplication] scheduleLocalNotification:notification]; //3

si vous souhaitez supprimer cette notification, faire

UIApplication *app = [UIApplication sharedApplication];
NSArray *eventArray = [app scheduledLocalNotifications];
for (int i=0; i<[eventArray count]; i++)
{
    UILocalNotification* oneEvent = [eventArray objectAtIndex:i];
    NSDictionary *userInfoCurrent = oneEvent.userInfo;
    NSString *uid=[NSString stringWithFormat:@"%@",[userInfoCurrent valueForKey:@"id"]];
    if ([uid isEqualToString:notification_id_to_remove])
    {
        //Cancelling local notification
        [app cancelLocalNotification:oneEvent];
        break;
    }
}

Très important!

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification n'a pas appelé, si vous en arrière-plan. Donc, vous devez d'installation de longue durée d'exécution en tâche de fond, où vous pourrez vous créer une notification de nouveau.
