Class

NSSwitch

A control that offers a binary choice.

Declaration

@interface NSSwitch : NSControl

Overview

The NSSwitch class provides a simple interface for displaying and toggling a Boolean state, such as on/off. A switch toggles its state and sends its action when clicked, activated through the keyboard, or tapped in the Touch Bar. NSSwitch also allows dragging between states, and if continuous is YES, the switch sends its action for each change in position during the drag.

Use a switch to toggle significant preferences, or preferences that provide access to other controls. Avoid creating lists or tables of switches; instead, for general-purpose toggles, use an instance of NSButton to display a checkbox.

NSSwitch doesn’t use an instance of NSCell to provide its functionality. The cellClass class property and cell instance property both return nil, and they ignore attempts to set a non-nil value.
