ABCircularProgressView

ABCircularProgressView is a simple circular progress view written in Swift 2, it draws the circular progress and a stop button (App store look like)

Screenshots:

An example in one of my apps. link:

ABCircularProgressView inherits from UIView, so you can just use it as a normal view in the Interface builder

Usage

//define it
@IBOutlet weak var progressView: ABCircularProgressView!

//start the spinning
progressIndicatorView.startSpinning()

//use it in the main thread
let dispatchTime: dispatch_time_t = dispatch_time(DISPATCH_TIME_NOW, Int64(2 * NSEC_PER_SEC));
let dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0)
dispatch_after(dispatchTime, dispatchQueue) { () -> Void in
    var progress: CGFloat = 0
    for i in 0..<101 {
        progress = CGFloat(Float(i) / 100.0)
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            self.progressIndicatorView.progress = progress
        })
        usleep(10000)
    }
}

Properties

####progress: CGFloat The the progress value. Between 0 and 100. Change its value in order to change the visual progress of the component. Default is 0.

####tintCGColor: CGColor The color of the progress view and the stop icon. Default is UIColor.blueColor().CGColor.

####stopSizeRatio: CGFloat Size ratio of the stop button related to the progress view, default 1/3 of the progress view. Default is 0.3.

####progressBackgroundOpacity: Float The Opacity of the progress background layer. Default is 0.1.

####lineWidth: CGFloat The width of the line used to draw the progress view. Default is 1.0.
