How to show local notification after one day or 24 hours in Objective C?

Question

I am new in iOS and I am facing problem regarding to show local notification.

Below is my code.

AppDelegate.m

-(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{

}

In viewDidLoad()

 defaultsnotification = [NSUserDefaults standardUserDefaults];

 UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
 UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
 [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];

  UILocalNotification* localNotification = [[UILocalNotification alloc] init];
  localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:0]; //Enter the time here in seconds.
  localNotification.alertBody = @"app Update Available";
  localNotification.timeZone = [NSTimeZone defaultTimeZone];
  localNotification.repeatInterval = NSCalendarUnitDay; //Repeating instructions here.
  localNotification.soundName = UILocalNotificationDefaultSoundName;
  [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

By using this code notification is calling After a minute. But I need to call it after 24 hours.

How can I do That?

Thanks in Advance!

try changing: localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:-20]; — Amit Tandel, Mar 07 '17 at 11:11
@AmitTandel No it is calling after minute Is anything I am doing wrong in code. — Muju, Mar 07 '17 at 11:21
Are you sure you are not adding other UILocalNotification, from some other code. Search for UILocalNotification in your project. — Amit Tandel, Mar 07 '17 at 11:27

Please update the following-

localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:(24*60*60)];

Try this :

- (void)applicationDidEnterBackground:(UIApplication *)application
{
UILocalNotification *notification = [[UILocalNotification alloc] init];
  notification.fireDate = [[NSDate date] dateByAddingTimeInterval:60*60*24];
 notification.alertBody = @"24 hours passed since last visit :(";
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}

Before that should dismiss all Notification....

In addition, i have to say, if you are using iOS 10 then you have to register your local notification, it means you are permitting your notification to fire on a desired time.
