2. It’s happening
3. WatchKit Apps Glances Notifications
4. Architecture
5. WKInterfaceController • Main class for WatchKit App • Manage interface elements on the watch • Respond to actions
6. Navigation patterns Hierarchical Page-based
7. Interface Elements • Labels • Images • Tables • Buttons • Switches • Sliders • Maps
8. Interface Elements Groups • Container for other elements • Horizontal or vertical layout • Nested groups possible
9. Interface Elements Menus • Provide context sensitive actions • Max. 4 items • Accessed via “force touch”
10. Interface Elements Dates and timers • Display date/time or timer • Formattable • Updated directly on the watch
11. Animations • Only possibility: Image sequences ◦ Static in Watch App ◦ Dynamically created in WatchKit Extension
12. Animations
13. Notifications The iOS device decides which notification is forwarded to the WatchApp • system provided short look notification • custom long look notification
14. Short Look nonscrollable, short overview of notification consits of: • app icon • title • application name
15. Long Look • defined per notification category • scrollable screen • non interactive items ◦ buttons addable via payload • static ◦ just customizable via storyboard • dynamic ◦ storyboard ◦ NotificationController class
16. Notification Interface • app icon • app name (customizable) • sash • content area • iOS app defined actions ◦ interactive notification actions ios8 ▪ foregound action (ios app) ▪ background action (WA, handle in interfaceController) • dismiss button
17. Sharing is Caring How to share data and communicate between your Watch App and iOS App. • App Groups • Direct Communication
18. App Groups • Can be enabled/created in App Project Settings -> Capabilities • iOS and Watch App connect to same group • Creates shared Container-Directory accessible via NSFileManager • UserDefaults: NSUserDefaults initWithSuiteName:
19. Direct Communication • While running the Watch App can communicate with the iOS App via: + (BOOL)openParentApplication: (NSDictionary *)userInfo reply:(void (^)( NSDictionary *replyInfo, NSError *error) )reply • iOS App handles it in appDelegate with: - (void)application: (UIApplication *)application handleWatchKitExtensionRequest: (NSDictionary *)userInfo reply:(void(^)( NSDictionary * replyInfo) )reply
