How to use

Customize Appearance

Colors and icon images are fully customizable. Either override or set preferred values.
Actually there's no default appearance, so have fun.👋

    open var defaultImage: UIImage?
    open var inProgressImage: UIImage?
    open var suspendedImage: UIImage?
    open var completedImage: UIImage?
    open var inProgressStrokeColor: UIColor?
    open var suspendedStrokeColor: UIColor?
    open var completedStrokeColor: UIColor?
    open var touchedAlpha: CGFloat = 0.5

UIImage's contentMode is .center. Make sure you provide correct size of image.

Update progress and state

state: updates color and icon image
progress: updates stroke progress
reset(): mutates both state and progress

It is possible to update progress while suspended.
state is read-only. Update via suspend(), resume(), complete() and reset().

Handle Tap

    private var token: CircleProgressButton.DisposeToken?

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        token = button.onTap { state in
             switch state {
             case .inProgress:
                print("suspend")
                self.stopJob()
             case .completed:
                print("delete")
                self.stopJob()
             case .default:
                print("start")
                self.resumeJob()
             case .suspended:
                print("resume")
                self.resumeJob()
             }
        }
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        token?.dispose()
    }

Using RxSwift

    override func viewDidLoad() {
        super.viewDidLoad()
        button.tapGesture.rx.event
            .subscribe(...)
            // ...
    }

For advanced touch interaction..

Feel free to assign your UIGestureRecognizerDelegate.

    button.tapGesture.delegate = self
