Hi, I’m Donny

Improving apps with iOS 10 notificationsBecause notifications can be pretty cool

Introduction to the UserNotifications framework

The bigger picture

iOS 7Text only notifications

Limited information and context

iOS 8Simple actions

Apple had a Text Input action for quick replies

iOS 9Developers could add the Text Input action

Less need to open the app

Everything < iOS 10

The difference between local and remote

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) { }

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { }

func application(_ application: UIApplication, didReceive notification: UILocalNotification) { }

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) { }

Everything < iOS 10

And of course, it all goes in AppDelegate

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) { }

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { }

func application(_ application: UIApplication, didReceive notification: UILocalNotification) { }

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) { }

Everything < iOS 10

Showing notifications while foregroundedThere’s one more thing…

iOS 10Media in notifications

Custom user interface

True end-to-end encryption

Unified framework

UserNotification at a glance

Unified Local and Remote

Single registration handler

Handle notifications through a delegate

Not compatible with < iOS 10

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { }

let notificationCenter = UNUserNotificationCenter.current() notificationCenter.getNotificationSettings { settings in if settings.authorizationStatus == .notDetermined { notificationCenter.requestAuthorization(options: [.badge, .alert]) { success, error in // handle status } } }

UserNotification at a glance

UserNotification at a glancelet content = UNMutableNotificationContent() content.title = “Next speaker"content.body = “Donny is up next" content.badge = 1

let path = Bundle.main.path(forResource: "thumbs", ofType: "png")! let imageUrl = URL(fileURLWithPath: path) let image = try! UNNotificationAttachment(identifier: "thumbs-up", url: imageUrl, options: nil) content.attachments = [image]

let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10, repeats: false) let request = UNNotificationRequest(identifier: “nextSpeaker", content: content, trigger: trigger)

notificationCenter.add(request, withCompletionHandler: nil)

And when you're in the foreground...

Service extensions

Hey there! What's up?

Service Extension

End to end encryption

Send push with mutable-content: 1

Service extensionsoverride func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { self.contentHandler = contentHandler decryptedContent = (request.content.mutableCopy() as? UNMutableNotificationContent) if let decryptedContent = decryptedContent { decryptedContent.title = "Updated title" contentHandler(decryptedContent) } }

Content extensionsView controller based extension

Extensions are tied to categories

Set content ratio in .plist

Actions are to added to notifications separately

<key>NSExtensionAttributes</key> <dict> <key>UNNotificationExtensionCategory</key> <string>wheel</string> <key>UNNotificationExtensionInitialContentSizeRatio</key> <real>1</real> </dict>

let content = UNMutableNotificationContent() content.title = "Spin the wheel?" content.body = "Win tickets for Do iOS" content.categoryIdentifier = "wheel" content.badge = 1

Content extensionsBring your own UI

Extensions don’t receive touches

Extensions do receive notification responses

Even less need for users to open your app

func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void) { if response.actionIdentifier == "spin" { wheel.spin() } }

Looking at the bigger picture

Stand out with Content Extensions

Design for short, quick interactions

Increased privacy with Service Extensions

Service Extension

Looking at the bigger picture

Cleaner code, more maintainable

Only send meaningful messages

Use identifiers to update notifications if needed

Thank you
