An interface with up and down arrow buttons for incrementing or decrementing a value.


class NSStepper : NSControl


A stepper consists of two small arrows that can increment and decrement a value that appears beside it, such as a date or time. The illustration below shows a stepper to the right of a text field, which would show the stepper’s value.

The NSStepper class uses the NSStepperCell class to implement its user interface.


Configuring the Cell

class NSStepperCell

An NSStepperCell object controls the appearance and behavior of an NSStepper object.

Specifying value range

var maxValue: Double

The stepper’s maximum value.

var minValue: Double

The stepper’s minimum value.

var increment: Double

The amount by which the receiver changes with each increment or decrement.

Specifying how the stepper responds

var autorepeat: Bool

A Boolean value that indicates how the stepper responds to mouse events.

var valueWraps: Bool

A Boolean value that indicates whether the stepper wraps around the minimum and maximum values.
