Question

hi, I want to upgrade to an older project to support slide view and split iOS 9 images, but I found that all the demo projects that I found were written in a storyboard or xib, but my old project user interface is written in code, can anyone Something to offer, thanks!

Answer 1

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

I highly recommend you watch the following WWDC videos, and then think about what you need to do to support multitasking.

Answer 2

Just FYI.
I could not accept Split View until I turned off this option in the project settings → Deployment information → (Switch iPad) → Status bar → Full screen required.

Answer 3

Just add the LaunchScreen layout and set it as LaunchScreen from the general settings of your project. You can save everything else as code.
