UIView subclass written in Swift to show circular progress.

Is your app using it? Let me know!

Please see the included example app for sample usage.

Styles

Indeterminate (spins infinitely)
Normal (set progress between 0.0 and 1.0)
Mixed (can make it indeterminate, but also animate progress to 1.0)

Public API

/**
 Enables or disables the indeterminate (spinning) animation

 - parameter enabled:    Whether or not to enable the animation (defaults to `true`)
 - parameter completion: An optional closure to execute after the animation completes
 */
open func enableIndeterminate(_ enabled: Bool = true, completion: CompletionBlock? = nil) {}

/**
 Updates the progress bar to the given value with the optional properties

 - parameter progress:     The progress to update to, pinned between `0` and `1`
 - parameter animated:     Whether or not the update should be animated (defaults to `true`)
 - parameter initialDelay: Sets an initial delay before the animation begins
 - parameter duration:     Sets the overal duration that the animation should complete within
 - parameter completion:   An optional closure to execute after the animation completes
 */
open func updateProgress(_ progress: CGFloat, animated: Bool = true, initialDelay: CFTimeInterval = 0, duration: CFTimeInterval? = nil, completion: CompletionBlock? = nil) {}

Properties

Note: Most properties below are @IBInspectable, but I don't use Interface Builder personally so let me know if you see any issues.

var trackTintColor: UIColor

The color of the empty progress track (gets drawn over)

var progressTintColor: UIColor

The color of the progress bar

var innerTintColor: UIColor?

The color the notched out circle within the progress area (if there is one)

var roundedCorners: Bool

Sets whether or not the corners of the progress bar should be rounded

var thicknessRatio: CGFloat

Sets how thick the progress bar should be (pinned between 0.01 and 1)

var clockwiseProgress: Bool

Sets whether or not the animation should be clockwise

var timingFunction: CAMediaTimingFunction

A timing function defining the pacing of the animation. Defaults to ease in, ease out.

var progress: CGFloat

Getter for the current progress (not observed from any active animations)

var indeterminateProgress: CGFloat

Sets how much of the progress bar should be filled during an indeterminate animation, pinned between 0.05 and 0.9
Note: This can be overriden / animated from by using updateProgress(...)

var indeterminateDuration: CFTimeInterval

Controls the speed at which the indeterminate progress bar animates

Supports

Swift, ARC & iOS 8+, Autolayout or springs and struts

A little help from my friends

Please feel free to fork and create a pull request for bug fixes or improvements, being sure to maintain the general coding style, adding tests, and adding comments as necessary.

Credit

This library is effectively a Swift port of DACircularProgress with some minor changes to the API, so it should be fairly easy to act as a replacement. I really loved that library but unfortunately it wasn't being maintained.
