Usage

Create and add a ColorSlider to your view:

let colorSlider = ColorSlider(orientation: .vertical, previewSide: .left)
colorSlider.frame = CGRect(x: 0, y: 0, width: 12, height: 150)
view.addSubview(colorSlider)

Respond to changes in color using UIControlEvents:

colorSlider.addTarget(self, action: #selector(changedColor(_:)), forControlEvents: .valueChanged)

func changedColor(_ slider: ColorSlider) {
    var color = slider.color
    // ...
}

Customize appearance attributes:

// Add a border
colorSlider.gradientView.layer.borderWidth = 2.0
colorSlider.gradientView.layer.borderColor = UIColor.white.cgColor

// Disable rounded corners
colorSlider.gradientView.automaticallyAdjustsCornerRadius = false

Preview

ColorSlider has a live preview that tracks touches along it. You can customize it:

let previewView = ColorSlider.DefaultPreviewView()
previewView.side = .right
previewView.animationDuration = 0.2
previewView.offsetAmount = 50

let colorSlider = ColorSlider(orientation: .vertical, previewView: previewView)

Create your own live preview by subclassing DefaultPreviewView or implementing ColorSliderPreviewing in your UIView subclass. Then, just pass your preview instance to the initializer:

let customPreviewView = MyCustomPreviewView()
let colorSlider = ColorSlider(orientation: .vertical, previewView: customPreviewView)

ColorSlider will automatically update your view's center as touches move on the slider. By default, it'll also resize your preview automatically. Set colorSlider.autoresizesSubviews to false to disable autoresizing.

To disable the preview, simply pass nil to ColorSlider's initializer:

let colorSlider = ColorSlider(orientation: .vertical, previewView: nil)

See the documentation for more details on custom previews.
