BlackBerry10 and iOS app SDK/Platform Comparison
0 likes438 views
BlackBerry 10 and iOS app development platforms share many similarities but also have some key differences. Both platforms use C/C++ for native development and support web apps. The platforms have similar services for notifications, cryptography, and allowing apps to interact. However, iOS is focused on one app at a time while BlackBerry emphasizes multitasking. BlackBerry 10 also allows more efficient peeking and uses sheets instead of action sheets.

- 2. Key Takeaways: Understand the similarities and difference between the platforms What’s different What’s the same Where differences matter 2
- 3. The Platforms 3 iOS (Kernel) & Drivers Core Services Graphics and Audio Application Frameworks [Maps, Message …] UIKit BB10 (QNX micro-kernel) & Drivers Core Services (/BPS) Graphics and Audio Application Frameworks [Qt, Maps, PIM, Share …] Cascades / QML Posix Webkit
- 4. Android Runtime, AIR Types of Apps 4 Web Apps Native with Webview PhoneGap… Native (Objective C and Cocoa Touch UIKit, OpenGL) Web Apps Native with Webview WebWorks, PhoneGap… Native (C/C++, QML, Cascades, OpenGL)
- 5. Objective C and C 5 #include <stdio.h>! #include <stdlib.h>! ! int ! main(int argc, char **argv)! {! fprintf(stdout, “Hello World!n”);! return EXIT_SUCCESS;! }!
- 6. C/C++ ! C/C++ is used widely due to it’s portability. It’s a true cross-platform language (combined with POSIX) ! Enables Lots of BB10 Open Source Frameworks ! iOS can also run C/C++ apps (Objective-C++). Developers are starting to look into this option for cross-platform savings. ! Simple on iOS (just rename your .m file into .mm and add objective-C+ +) 6
- 9. XCode 9
- 10. Platform Services 10 ! BB10 is playing catch-up to iOS in SDK features and services ! Lots of similarities between key features … ! Differences to be discussed…
- 11. Thoughts… ! iOS ! Facebook/Twitter Connect APIs ! Background (/Headless) services ! VOIP ! Custom Navigation Apps ! Music / Downloads /Services 11
- 12. Cryptography* ! iOS and BB10 … similar features ! AES,DES,3DES… ! Key difference BB10 crypto algorithms are FIPS certified ! What the FIPS? Only Modules validated as conforming to FIPS 140-2 are accepted by the Federal Agencies of Canada/US for the protection of sensitive information.
- 13. Service similarities (Invoke) 13 I need to open this .doc file. Anyone? I can open .doc files Invocation Framework
- 15. Similarities in UX ! Apple Says ! The Display Is Paramount ! Regardless of Its size ! Apps Respond to Gestures, Not Clicks ! RIM Says ! Content is King ! Apps must Flow 15
- 16. Notifications 16
- 17. BB10 Peek is more efficient 17 ! Apple concept of page curl ! Not as universal
- 18. A key difference ! Apple Says ! People interact with One App at a Time ! RIM Says ! Extend/Connect ! BlackBerry people Multi-Task ! Combine that with Peek and Viewers/Cards 18
- 19. Application Behavior Lifecycle and when to store your data • Must respond correctly to lifecycle events • Can drain battery • Must store data efficiently 19 Start Exit Normal (Active) Thumbnail (Active/Inactive) Hidden (Inactive)
- 20. iOS Lifecycle 20 ! Long-Running Background Tasks ! Audio ! Location/Navigation ! VOIP ! Newsstand apps (downloads etc…) ! Accessory apps
- 21. Sample Project Podcast App (Work in progress. Blog installments)
- 23. UI Design (iOS storyboards) 23
- 24. BB10 Qt/QML 24
- 27. Lists Summary ! iOS Storyboards are Visually appealing but … QML/Qt is just as descriptive. ! Data binding to Lists is much easier in Cascades than on iOS 27
- 28. Similar UI (notice subtle UX diff’s) 28
- 31. A closer look at applications
- 32. Navigation Bar / Action Bar 32
- 33. Settings / App Menu 33
- 34. Tab Bar 34
- 35. Tab Overflows (BB10 Sidebar) 35
- 36. Context Menu 36 toolbar Custom buttons in the navigation bar
- 37. BB10 has an action bar overflow 37
- 39. WebView and WebView (webkit) 39
- 40. Action Sheets / Sheets 40
- 41. Cascades Sheets A sheet breaks the current navigational flow. It contains a subflow that need to be finished before the original application flow can be resumed. Examples: Pickers, Forms 41
- 43. iOS Controls 43
