Usage

Interface Builder

Simply drag a UIView into your storyboard. Make sure to subclass UICircularProgressRing and that the module points to UICircularProgressRing.

Design your heart out

Code

override func viewDidLoad() {
  // Create the view
  let progressRing = UICircularProgressRing(frame: CGRect(x: 0, y: 0, width: 240, height: 240))
  // Change any of the properties you'd like
  progressRing.maxValue = 50
  progressRing.innerRingColor = UIColor.blue
  // etc ...
}

To set a value and animate the view

// Somewhere not in viewDidLoad (since the views have not set yet, thus cannot be animated)
// Remember to use unowned or weak self if refrencing self to avoid retain cycle
progressRing.startProgress(to: 49, duration: 2.0) {
  print("Done animating!")
  // Do anything your heart desires...
}

// Pause at any time during a running animation
progressRing.pauseProgress()

// Continue where you left off after a pause
progressRing.continueProgress()
