BlackBerry10 and iOS app SDK/Platform Comparison
0 likes435 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.

- 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

- 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.
