LOCAL NOTIFICATIONS

@KRISTINATHAI

LOCAL NOTIFICATIONSLike push notifications, but scheduled locally

Handled by UNUserNotificationCenter(allows management of duplicates sent to both devices)

@KRISTINATHAI

// Create the content let content = UNMutableNotificationContent() content.title = NSString.localizedUserNotificationString(forKey: "Hello!", arguments: nil) content.body = NSString.localizedUserNotificationString(forKey: "Hello_message_body", arguments: nil) content.sound = UNNotificationSound.default()

// Deliver the notification in five seconds. let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false) let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger:trigger)

// Schedule the notification. let center = UNUserNotificationCenter.current() center.add(request)

Create custom responses for your notifications

@KRISTINATHAI

Respond to custom notification action

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { if response.actionIdentifier == "Complete" { //Handle response here } }
