Question

In iOS 9, is it possible to detect when an app is running in iOS 9\'s Slide Over or Split View mode?

Answer 1

You can watch both -willTransitionToTraitCollection:withTransitionCoordinator: for the size class and viewWillTransitionToSize:withTransitionCoordinator: for the CGSize of your view. Hardcoding in size values isn't recommended though.
