NSAccessibilityStepper
A role-based protocol that declares the minimum interface necessary for an accessibility element to act as a stepper.
Declaration
protocol NSAccessibilityStepper : NSAccessibilityElementProtocolOverview
Use this protocol when you want a user interface element to behave like a stepper—a control with up and down arrow buttons for incrementing or decrementing a value—in the accessibility hierarchy.
You can further enhance the adopting element by implementing any of the information properties or action methods that the NSAccessibilityProtocol protocol declares.
