ActivityRings
ActivityRings is an attempt to recreate the ring controls in Apple’s Activity app.
This project is a SpriteKit port of Max Konovalov’s pure UIKit implementation, MKRingProgressView.
Requirements
- Swift 4.2
- iOS 8.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 4.0+
Installation
ActivityRings is available via CocoaPods and Carthage.
CocoaPods
To install ActivityRings using CocoaPods, add the following line to your Podfile:
pod 'ActivityRings'
Carthage
To install ActivityRings using Carthage, add the following line to your Cartfile:
github "HarshilShah/ActivityRings"
Usage
Basics
To get started, import ActivityRings. To display the control, use the ActivityRingView class on iOS, macOS, and tvOS, and the ActivityRingScene class on watchOS.
Customisation
The ringWidth, the startColor, the endColor, and the backgroundRingColor can all be customised.
Progress
The progress of the ring can be set with or without animation.
To set the progress without animation, simply update the value of the progress variable.
To animate the progress, use the animateProgress method, which accepts two arguments:
- The desired final progress value
- The animation duration
Notes
Some notes on performance:
- Since this control was written in SpriteKit, it relies heavily on the GPU, and so will not perform well or accurately in the simulator.
- The initial setup process is somewhat expensive, so animating the progress directly after presenting the view can cause some hiccups. This is being worked on, but in the meantime, delaying the animation by a second or so works around the issue.
