PRGRoundSlider

PRGRoundSlider is a flexible and customizable implementation of a circular slider view.

It is written in Swift 3.0 and Compatible with iOS 8.0+

Usage

To start using the component add it to your project manually as per the Installation section.

Storyboard

The UI components can be used via the PRGRoundSlider or PRGRoundRangeSlider class.

To create an instance of the class, drag a UIView from the Interface builder and set it's class to PRGRoundSlider for single thumb slider or PRGRoundRangeSlider for a range slider.

PRGRoundSlider and PRGRoundRangeSlider are @IBDesinable and customizable via @IBInspectable properties, this way almost everything can be done via the interface builder.

Programmatically

func setupSliderProgrammatically(){
    let sliderView = PRGRoundSlider(
    frame: sliderContainerView.bounds,
    value: 0.5,
    strokeColor: SliderKit.darkBlueColor,
    strokeWidth: 3,
    gradientColor: SliderKit.darkPinkColor,
    startAngle: 210,
    endAngle: -30,
    startText: "0%",
    endText: "100%")
{ (value) in
    return "\(Int(value*100))%"
}


sliderContainerView.addSubview(sliderView)
}

The properties are pretty straightforward but here are the most important things you need to know:

Appearance

strokeColor, innerStrokeColor, gradientColor:

The stroke color of the slider curve, the color of the inner stroke that is found inside the central message circle and a supplementary bottom color if you need to give a gradient look.

@IBInspectable var strokeColor: UIColor
@IBInspectable var innerStrokeColor: UIColor
@IBInspectable var gradientColor: UIColor 

thumbColor:

The color of the slider thumb.

@IBInspectable var thumbColor: UIColor

messageColor:

The text color of the message in the center of the circle.

@IBInspectable var messageColor: UIColor

strokeWidth:

The width of the slider stroke

@IBInspectable var strokeWidth: CGFloat

startAngle, startText, endAngle, endText, startEndColor:

the angle of the slider start and end points, their respective text as well as the text color

@IBInspectable var startAngle: CGFloat
@IBInspectable var startText: String
@IBInspectable var endAngle: CGFloat
@IBInspectable var endText: String
@IBInspectable var startEndColor: UIColor

Internal Stuff

value (for the single thumb slider):

The value of the slider (0 - 1)

@IBInspectable var value: CGFloat = 0

startValue & endValue (for the rangle slider):

The start and end values of the slider (0 - 1)

@IBInspectable var startValue: CGFloat
@IBInspectable var endValue: CGFloat

messageForValue:

You can use this if you want to customize the message shown in the center circle:

For the single thumb slider:

sliderView.messageForValue = { (value) in
    return "\(Int(value*100))%"
}

For the range slider:

sliderView.messageForValue = { (startValue,endValue) in
    return "\(Int(startValue*100))%-\(Int(endValue*100))"
}
