splitViewController(_:willHide:with:for:)

Tells the delegate that the specified view controller is about to be hidden.

Declaration

optional func splitViewController(_ svc: UISplitViewController, willHide aViewController: UIViewController, with barButtonItem: UIBarButtonItem, for pc: UIPopoverController)

Parameters

  • svc:

    The split view controller that owns the specified view controller.

  • aViewController:

    The view controller being hidden.

  • barButtonItem:

    A button you can add to your toolbar.

  • pc:

    The popover controller that uses taps in barButtonItem to display the specified view controller.

Discussion

When the split view controller rotates from a landscape to portrait orientation, it typically hides one of its view controllers. When that happens, it calls this method to coordinate the addition of a button to the toolbar (or navigation bar) of the remaining custom view controller. If you want the soon-to-be hidden view controller to be displayed in a popover, you must implement this method and use it to add the specified button to your interface.
