Update your icon and badge
Simple!
Update Icon
-[UIApplication setNewsstandIconImage:(UIImage*)]
• Bisa digunakan saat berjalan di background, jadi bisa diupdate kapanpun jika konten sudah siap.
Update Badge
• Uses existing badge API
-[UIApplication setApplicationIconBadgeNumber:(NSInteger)]](https://image.slidesharecdn.com/ios5newstuffnew-120225140747-phpapp02/85/iOS5-NewStuff-59-320.jpg)
iOS5 NewStuff
- 1. iOS 5 New Stuff R.Ayu Maulidina.I.
- 2. Over 200 new user features
- 3. SDK & Development tools? over 1,500 new APIs and powerful new development tools
- 4. iCloud Storage API Apa itu iCloud? - Sync service - Transfers user data between devices - Runs in background - Per-app sandboxing (as usual) Keuntungannya Apa ? - Gak perlu ‘sync server’ sendiri. - Gak perlu ‘network protocol’ sendiri. - Gak perlu bayar ‘storage/bandwidth’ sendiri. Intinya sih gak perlu repot-repot.
- 5. Konsep dan Ketentuan iCloud Ubiquitous Suatu keadaan yang memungkinkan manusia untuk berinteraksi dengan ‘komputer’ dimana saja, kapan saja dan bagaimana saja.
- 6. Sinkronisasi Background Ubiquity daemon, ubd Saat anda menyimpan perubahan, ubd mengirimkannya pada ‘cloud’ ubd akan mengunduhnya dari iCloud Dimana itu berarti....
- 7. Data anda dapat berubah tanpa peringatan..
- 8. iCloud Containers Lokasi untuk data aplikasi anda berada di iCloud Setiap pengaktifan iCloud pada aplikasi setidaknya hanya memiliki satu tempat. Kontainer sesuai dengan direktori yang kita buat
- 9. File Coordinator Data dapat diubah oleh aplikasi anda atau oleh ubd (Ubiquity Daemon) Membutuhkan ‘reader/writer lock’ untuk akses koordinasi Menggunakan ‘NSFileCoordinator’ saat menulis atau membacanya
- 10. File Presenter Disertakan juga pada file koordinator Menerapkan ‘NSFilePresenter’ agar mendapat pemberitahuan akan adanya perubahan Saat file koordinator membuat perubahan, maka ‘file presenter’ ini akan dipanggil.
- 11. iCloud APIs Key-value store Core Data Document
- 12. Gimana cara mengaktifkan iCloud ? App ID on Provisioning Portal ---> developer.apple.com/ios/ ---> app IDs
- 14. Peringatan!
- 15. Configuration name for identifier, entitlements file, iCloud key-value store, containers and keychain access groups.
- 18. UIDocument Asynchronous block-based reading and writing Auto-saving Flat file and file packages
- 19. UIDocument with iCloud Acts as a file coordinator and presenter Mendeteksi conflicts - Notifications - API to help resolve
- 20. UIDocument Concepts Outside the (sand)box - iCloud documents are not located in your app sandbox - Located in your iCloud container - Create the document in the sandbox - Move it to iCloud
- 23. Subclassing UIDocument @interface NoteDocument : UIDocument @property (strong, readwrite) NSString *documentText; @end

- 41. Detector Option Keys Keys used in the options dictionary to configure a detector. Detector Accuracy Options NSString* const CIDetectorAccuracyLow; NSString* const CIDetectorAccuracyHigh; - CIDetectorAccuracyLow Indicates that the detector should choose techniques that are lower in accuracy, but can be processed more quickly. - CIDetectorAccuracyHigh Indicates that the detector should choose techniques that are higher in accuracy, even if it requires more processing time.
