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

UICircularProgressRing Example

override func viewDidLoad() {
  // Create the view
  let progressRing = UICircularProgressRing()
  // Change any of the properties you'd like
  progressRing.maxValue = 50
  progressRing.style = .dashed(pattern: [7.0, 7.0])
  // 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 referencing 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()

UICircularTimerRing Example

override func viewDidLoad() {
	// create the view
	let timerRing = UICircularTimerRing()
}

Animate and set time

						// seconds
timerRing.startTimer(to: 60) { state in
    switch state {
    case .finished:
        print("finished")
    case .continued(let time):
        print("continued: \(time)")
    case .paused(let time):
        print("paused: \(time)")
    }
}

timerRing.pauseTimer() // pauses the timer

timerRing.continueTimer() // continues from where we paused

timerRing.resetTimer() // resets and cancels animations previously running
