I have put the stepper in a tableViewCell, and for testing purposes every time the cell is show, the tint color is chosen randomly so, so once they go out of view, and come back they will have new color. After coming back into view.

fix would be to add these into func tintColorDidChange()

increaseLayer.strokeColor = tintColor.cgColor
decreaseLayer.strokeColor = tintColor.cgColor

I installed using Pod as indicated. Made no changes and instantly had the error. "Shared" is unavailable. Use New Controller based solution.

Using Xcode 8.3.3. Thanks for your help! Howard

/// - decrease: decrease button has tag 0. /// - increase: increase button has tag 1. private enum Button: Int { case decrease case increase }

You can not set the tag value of an element to 0. Need to modify that logic in order to get elements by tag value correctly.

/// - decrease: decrease button has tag 1. /// - increase: increase button has tag 2. private enum Button: Int { case decrease = 1 case increase = 2 }

The return statement on lines 255 and 265 prevent a normal tap from changing the value and forces the user to tap+hold to change the value when autorepeat is enabled. Removing these two lines will cause the control to behave like the standard UIStepper where a tap+release will change the value by the step amount exactly once and a tap+hold will still autorepeat the value change.

Fixed #1

It's now possible to customize or provide a NSNumberFormatter object in this way:

let moneyFormatter = NSNumberFormatter()
moneyFormatter.numberStyle = .CurrencyStyle
moneyFormatter.maximumFractionDigits = 0
stepper.numberFormatter = moneyFormatter

Or simply modify the default NSNumberFormatter:

stepper3.numberFormatter.maximumFractionDigits = 1

There is a subtle bug in labelPressed function on line 360. The following line of code if newValue >= self.minimumValue || newValue <= self.maximumValue must be replaced by if newValue >= self.minimumValue && newValue <= self.maximumValue

The || operator must be replaced by && operator.

Hi I am receiving this error when updating Carthage. Can you help?

*** Skipped building ValueStepper due to the error: Dependency "ValueStepper" has no shared framework schemes

Thanks WTBM

What's in this PR?

I started using this component in a small side project and was in need for a bit more customization.

• Add disabledButtonColor which can be used to set a custom color used by the +/- buttons when they are disabled and no input is possible.
• Add highlightedBackgroundColor which can be used to set a custom background color for the +/- buttons which was defaulting to .gray which might not be desired when using the stepper on brighter brackgrounds.
• Add another stepper to the example project showcasing the added color properties.

fix to #13 (a noob here so do I need to create an issue first and then do a PR?)

this part of code fixes issue where incrementing/decrementing is in infinite loop and when pressed + or - stops the it, attached a gif. also removes redundant continuousTimer?.invalidate() calls that can be replaced with continuousTimer = nil

private var continuousTimer: Timer? {
    didSet {
        if let timer = oldValue {
            timer.invalidate()
        }
    }
}

Adding an event action .touchCancel fixed the issue with infinite increment/decrement. choose to add it to decrease()/increate selector so its responsive to user interaction, but could be attached to the stopContinuous of increase and decrease button. [around line 140]

decreaseButton.addTarget(self, action: #selector(decrease(_:)), for: [.touchUpInside, .touchCancel])
increaseButton.addTarget(self, action: #selector(increase(_:)), for: [.touchUpInside, .touchCancel])

In current version increase and decrease buttons becomes disabled when _value ± stepValue ≥≤ max/min, but condition **equal**_ means what we can perform one more step.

GitHub changed the way Markdown headings are parsed, so this change fixes it.

Hello, please add a callback If user Increment or decrement it would be a lot easier for us thanks, because for now we need to store the previous value to check if it's +1 / - 1

Pod library is not working for extension, I tried to set Require only app-extension-safe api to NO, but didn't work. I am using the extension for remote notification. Please let me know if there is any workaround

When we use ValueStepper in collectionView Cell, every time reusable cell is allocated, ValueStepper calls target method even though when it is not required. Also when altering value of the stepper, target method is called. What I think is you can remove Action(for:) from DidSet of value variable.

ValueStepper.swift line 205

override open static var requiresConstraintBasedLayout: Bool 

produces error:

Static declarations are implicitly 'final'; use 'public' instead of 'open'
