Installation

UICircleProgressView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'UICircleProgressView'

Example

Use either:

  • the Interface-Builder to create a UIView and set it's base-class to UICircleProgressView
  • create a UICircleProgressView in source:
import UICircleProgressView

let progressView = UICircleProgressView(frame: CGRect(x: 0, y: 0, width: 24, height: 24), style: .new, status: .waiting)
progressView.tintColor = .blue

// starting download...
progressView.status = .downloading

for progress in stride(from: 0.0, to: 1.0, by: 0.01) {
    progressView.progress = CGFloat(progress)
    usleep(20000)
}
progressView.status = .success

For a full example-project see: example.xcodeproj or just the ViewController.swift

Usage

The following properties are exposed to customize and controll the progressView:

property behavior type / values
status the current progess-state enum: DownloadStatus
[.paused,.waiting,
.downloading,.success,
.canceled]
style the UI-style of the progressView enum: StyleType
[.old,.new]
progress the current progress Float (0.0 - 1.0)
strokeWidth explicitly set the progress-circle stroke width CGFloat
strokeDynamic use either: the explicit strokeWidth value for the progress-circle stroke, or calculate it dynamically Bool
colorSuccess/
colorPaused/
colorCanceled/
tintColor		 set the progress colors UIColor

All of these properties can also be set in the XCode-Interfacebuilder, thanks to @IBDesignable:

Button

This library also offers a button-version of the circle-progress to mimic the AppStore download-buttons. The usage is mostly identical to the progressView, just use UICircleProgressButton instead.

Additionally to the described properties of the progressView, the Button supports:

property behavior type / values
startImage the button imageview which should be shown when the progress is currently stopped UIImage?
stopImage the button imageview which should be shown when the progress is currently downloading/waiting UIImage?
