how to transition an older project whose UI is written by code to support Slide Over and Split View of iOS 9?

Question

hi，I want to transition an an older project to support Slide Over and Split View of iOS 9，but I find all the demo projects I found was written by storyboard or xib, but my older project's UI is written by code, can any one suggest, thanks!

Answer 1

Just FYI.
I was not able to adopt Split View until disabled this setting in Project settings->Deployment Info->(Switch iPad)->Status Bar Style->Requires full screen.

Answer 2

I would suggest switching to storyboards to make your life easy.

I would highly recommend you watch the following WWDC videos and then think about what exactly you need to do in order to support multi tasking.
