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
