Manual Installation

The class file required for MTCircularSlider can be found in the following path:

MTCircularSlider/Classes/MTCircularSlider.swift

Usage

MTCircularSlider implements IBDesignable and IBInspectable, and so can be configure directly from Interface Builder.

Usage in Code - Simple

To add a default circular slider, add the following code to your controller:

self.slider = MTCircularSlider(frame: self.sliderArea.bounds, options: nil)
self.slider?.addTarget(self, action: Selector("valueChange:"), forControlEvents: .ValueChanged)
self.sliderArea.addSubview(self.slider)

Usage in Code - Advanced

To add a custom circular slider, add the following code to your controller:

let attributes = [
/* Track */
Attributes.minTrackTint(.lightGray),
Attributes.maxTrackTint(.lightGray),
Attributes.trackWidth(12),
Attributes.trackShadowRadius(0),
Attributes.trackShadowDepth(0),
Attributes.trackMinAngle(180),
Attributes.trackMaxAngle(270),

/* Thumb */
Attributes.hasThumb(true),
Attributes.thumbTint(UIColor.darkGrayColor()),
Attributes.thumbRadius(8),
Attributes.thumbShadowRadius(0),
Attributes.thumbShadowDepth(0)
]

self.slider = MTCircularSlider(frame: self.sliderArea.bounds, options: nil)
self.slider.configure(attributes)
self.slider?.addTarget(self, action: Selector("valueChange:"), forControlEvents: .ValueChanged)
self.sliderArea.addSubview(self.slider)
