Protocol Implementations

Overview

NSSplitViewController conforms to NSSplitViewDelegate to serve as its split view’s delegate. This page lists the split view controller type’s implementations of those protocol methods. If you override these methods in a subclass, you must call super.

NSSplitViewController also conforms to NSUserInterfaceValidations by implementing validateUserInterfaceItem(_:).
