MultiSlider

UISlider clone with multiple thumbs and values, optional snap intervals, optional value labels.

Usage

let slider   = MultiSlider()
slider.minimumValue = 1    // default is 0.0
slider.maximumValue = 5    // default is 1.0
slider.snapStepSize = 0.5  // default is 0.0, i.e. don't snap

slider.value = [1, 4.5, 5]

slider.addTarget(self, action: #selector(sliderChanged(_:)), forControlEvents: .ValueChanged)

Getting Multiple Thumb Values

func sliderChanged(slider: MultiSlider) {
    print("\(slider.value)")
}

Changing Appearance

slider.thumbImage   = UIImage(named: "baloon")
slider.minimumImage = UIImage(named: "clown")
slider.maximumImage = UIImage(named: "cloud")
slider.trackWidth = 5
slider.tintColor = .cyanColor()

Adding Labels Showing Thumb Value

slider.valueLabelPosition = .Left // .NotAnAttribute = don't show labels
slider.isValueLabelRelative = true // shows differences instead of absolute values

Disabling/Freezing Thumbs

slider.disabledThumbIndices = [1, 3]

Installation

CocoaPods:

pod 'MultiSlider'

Manually:

Copy Sources/MultiSlider.swift and MiniLayout.swift to your Xcode project.

TODO

• Horizontal slider and not just vertical.
• isContinuous=false for clients that only want a single .valueChanged event on drag end.
• Fix IB presentation. (dlopen error "image not found", thumbs should be vertically centered and evenly distributed.)
