Looking for people to help maintain and contribute, email me here

Features

Interface builder designable
Highly customizable
Animation for progress and value text built in
Written in Swift 3 and using Xcode 8

Installation

CocoaPods (Recommended)

Install CocoaPods

Add this repo to your Podfile

target 'Example' do
	# IMPORTANT: Make sure use_frameworks! is included at the top of the file
	use_frameworks!

	pod 'UICircularProgressRing'
end

Run pod install
Open up the .xcworkspace that CocoaPods created
Done!

Note: If you have any issues with Swift 3 and CocoaPods you can try to force the version. (Cocoapods support for Swift 3 projects has been a bit wonky).

Add this to the end of your Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |configuration|
      configuration.build_settings['SWIFT_VERSION'] = "3.0"
    end
  end
end

Carthage

Important note: Carthage support for IBDesignable and IBInspectable is broken due to how frameworks work. So if you decide on using Carthage, you will not be able to use IB to design this view. Take a look here for the issue.

To use with Carthage

Make sure Carthage is installed

brew install carthage
Add this repo to your Cartfile

github "luispadron/UICircularProgressRing"
Drag the UICircularProgressRing.framework from MyProjDir/Carthage/Builds/iOS/UICircularProgressRing into the General -> Embeded Binaries section of your Xcode project.

Manually

Simply download the UICircularProgressRingView.swift, UICircularProgressRingLayer.swift and UICiruclarProgressRingDelegate.swift files from here into your project, make sure you point to your projects target

Usage

Interface Builder

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

Design your heart out

Code

override func viewDidLoad() {
  // Create the view
  let progressRing = UICircularProgressRingView(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.setProgress(value: 49, animationDuration: 2.0) {
  print("Done animating!")
  // Do anything your heart desires...
}
