I understood! I shouldn't perform the segue if the splitViewController isn't collapsed. I already have the controller. Sorry )

Hi! Really useful code. Thank you. I have the only problem in the expanded mode: I set up my master-detail configuration in the storyboard and I have a "Show detail" segue from my master UITableViewController to my detail UIViewController. When this segue performs, the displayModeButtonItem disappears. Can't find any solution. Thank you in advance for your help.
