ValueStepper is an improved replication of Apple's UIStepper object. The problem with UIStepper is that it doesn't display the value to the user. I was tired of creating a simple UILabel just to show the value in the UI. ValueStepper integrates the value in a UILabel between the increase and decrease buttons. It's as easy as that.


To see it in action, run the example project, clone the repo, and run pod install from the Example directory first. The example project shows how to set up ValueStepper in Storyboard.


Drag a UIView object and set the class to ValueStepper (if needed set the module to ValueStepper too). You can now customize all the properties in IB such as the minimumValue, tintColor and so on. Make sure to set the width to 149 and the height to 29 which are the default values. Create an @IBAction on the ValueChanged control event to be notified when the value changes.


import ValueStepper

let valueStepper: ValueStepper = {
    let stepper = ValueStepper()
    stepper.tintColor = .whiteColor()
    stepper.minimumValue = 0
    stepper.maximumValue = 1000
    stepper.stepValue = 100
    return stepper

override func viewDidLoad() {
    valueStepper.addTarget(self, action: "valueChanged:", forControlEvents: .ValueChanged)

@IBAction func valueChanged1(sender: ValueStepper) {
    // Use sender.value to do whatever you want


These are the available properties with the relative documentation.

/// Current value and sends UIControlEventValueChanged when modified.
@IBInspectable public var value: Double = 0.0

/// Minimum value that must be the less than the maximum value.
@IBInspectable public var minimumValue: Double = 0.0

/// Maximum value that must be greater than the minimum value.
@IBInspectable public var maximumValue: Double = 1.0

/// The value added/subtracted when one of the two buttons is pressed.
@IBInspectable public var stepValue: Double = 0.1

/// When set to true, keeping a button pressed will continuously increase/decrease the value every 0.1s.
@IBInspectable public var autorepeat: Bool = true

/// Describes the format of the value.
public var numberFormatter: NSNumberFormatter

// Default width of the stepper. Taken from the official UIStepper object.
public let defaultWidth = 141.0

// Default height of the stepper. Taken from the official UIStepper object.
public let defaultHeight = 29.0


ValueStepper is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ValueStepper'

You can also use Carthage if you prefer. Add this line to your Cartfile.

github "BalestraPatrick/ValueStepper"


iOS 8.3 and Swift 3.0 are required.

If you are using Swift 2.3, use the swift-2.3 branch.
