How to work with Local Notification

do some code with app delegate files:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//
//
   
    UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotification) {
        NSLog(@"Notification Body: %@",localNotification.alertBody);
        NSLog(@"%@", localNotification.userInfo);
       
  //NSString *reminderText = [localNotification.userInfo objectForKey:@"kRemindMeNotificationDataKey"];
        //[viewController showReminder:reminderText];
    }
   
    application.applicationIconBadgeNumber = 0;
}

-Then use Local NotoficationDelegate method :

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    NSLog(@"Notification Body: %@", notification.alertBody);
    NSLog(@"%@", notification.userInfo);
   
    application.applicationIconBadgeNumber = 0;
}
