RangeSlider

RangeSlider is a clean, simple, and attractive range-based slider control for Mac, written in Swift.

It is similar to NSSlider except that it affords two control points (start and end knobs), useful when users need to select a range of values.

Features:

Simple, easy-to-use
Flexible resizing
Customizable
Snap-to-interval (optional)
Several built-in styles

Demo

How To Use

Add to XIB or create programmatically. Example: let slider = RangeSlider(frame:sliderFrame)
(Optional) Set the min/max values (default: 0.0-1.0)
(Optional) Set the start/end values (default: 0.0-1.0)
(Optional) Enable snapping (snapsToIntegers = true)
(Optional) Adjust style options (colorStyle, knobStyle)

Responding to Changes

Once the slider is configured, you can respond to changes by observing the start/end (or length) values, or using the onControlChanged property.

Example:

mySlider.onControlChanged = {
    (slider: RangeSlider) -> Void in
    print("Slider changed! Start:\(slider.start) End:\(slider.end) Range:\(slider.length)")
}

ToDo's

RangeSlider is still a work-in-progress. A few of the known issues / ToDo's remaining:

Fix clipping of knob shadows, especially for circular slider style
General cleanup, refactoring
Fix knobs being allowed to overlap
Improve border stroke of circular knob style
Accessibilty support + highlighting/focus and other control behaviors

System Requirements

RangeSlider is currently macOS-only, however it could easily be updated to work with UIKit. Please file an Issue or feel free to submit a Pull Request if you'd like iOS support.
