MKRingProgressView

Language Platform License Version Carthage compatible

Ring progress view similar to Activity app on Apple Watch

MKRingProgressView

Features

  • Progress animation
  • Customizable start/end and backdrop ring colors
  • Customizable ring width
  • Customizable progress line end style
  • Customizable shadow under progress line end
  • Progress values above 100% (or 360°) can also be displayed

Installation

CocoaPods

To install MKRingProgressView via CocoaPods, add the following line to your Podfile:

pod 'MKRingProgressView'

Carthage

To install MKRingProgressView via Carthage, add the following line to your Cartfile:

github "maxkonovalov/MKRingProgressView"

Usage

See example Xcode project. It also contains additional classes for convenient grouping of 3 ring progress views replicating Activity app by Apple.

Interface Builder

MKRingProgressView can be set up in Storyboard. Specify startColor, endColor, ringWidth and optional backgroundRingColor (if not set, defaults to startColor with 15% opacity).

Code

let ringProgressView = RingProgressView(frame: CGRect(x: 0, y: 100, width: 100, height: 100))
ringProgressView.startColor = .red
ringProgressView.endColor = .magenta
ringProgressView.ringWidth = 25
ringProgressView.progress = 0.0
view.addSubview(ringProgressView)

The progress value can be animated the same way you would normally animate any property using UIView's block-based animations:

UIView.animate(withDuration: 0.5) {
    ringProgressView.progress = 1.0
}

Performance

To achieve better performance the following options are possible:

  • Set gradientImageScale to lower values like 0.5 (defaults to 1.0)
  • Set startColor and endColor to the same value
  • Set shadowOpacity to 0.0
  • Set allowsAntialiasing to false

Requirements

  • iOS 8.0
  • Xcode 9, Swift 4
