I was using the circle slider for my app, when this happened:

private func redraw() {
    self.trackLayer.removeFromSuperlayer()
    self.trackLayer = TrackLayer(bounds: self.bounds, setting: self.createLayerSetting())
    self.thumbView.removeFromSuperview()
    self.thumbView = UIView(frame: CGRect(x: 0, y: 0, width: self.thumbWidth, height: self.thumbWidth))
    self.layout(self.latestDegree)
  }

It called a EXC Bad Instruction on the .removeFromSuperlayer(). This is part of the framework.

When I run on a physical device, I get EXC_BREAKPOINT and my view won't load.

The cause may have been when I used

circleSlider.addTarget(self, action: #selector(TodayViewController.chngVol(_:)), forControlEvents: .ValueChanged)

without specifying it as an Optional, as Xcode wouldn't let me make it an Optional.

How should I fix this?!

Usually I use sender.value to get the current value but I can't do that with this library. Only UILabel can get the current value such as the example down there? But I want to use it as float and send it to another function, what can I do?

func valueChange(sender: CircleSlider) { switch sender.tag { case 0: self.valueLabel.text = "(Int(sender.value))" case 1: self.progressLabel.text = "(Int(sender.value))%" default: break } }

When the value property is set programatically and then the component re-renders, the slider position resets to a previous state and the UI no longer matches the value property.

The fix is to update latestDegree when the value is set explicitly.

Hi, I wanted to try your pod, but I had following problems. I managed to overcome them (leave my solutions for reference), but it think it could be fixed for other users:

1. pod try CircleSlider doesn't work - I had to clone repository
2. pod install (in Example directory) doesn't work - I changed Podfile and removed exclusive part (after name and before 'do')
3. example didn't start due to provisioning profile problems - I changed profile to mine.
4. example didn't build due to provisioning problems in test project - (again changed profile)

(I don't know if 3 and 4 are fixable, but let's hope so :) )

Also pod install throws some warnings and on IPhone 5C sliders overleap with progress circle (but it doesn't make it unreadable).

Thank you for this pod. I think it will really help me.

hello I am used few to slider

 @IBOutlet weak var FoodQSlider      : UIView!
    @IBOutlet weak var Cleanness        : UIView!
    @IBOutlet weak var StaffPerformance : UIView!
    @IBOutlet weak var Facilities       : UIView!
    @IBOutlet weak var InternetService  : UIView!
    @IBOutlet weak var AccToBazzar      : UIView!
    @IBOutlet weak var AccToEntertain   : UIView!

and The initialization all have

let delay = 0.1 * Double(NSEC_PER_SEC) let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay)) dispatch_after(time, dispatch_get_main_queue(), { self.circleSlider.value = Float(self.reviwesRoundTwo[0]) }) but only last slide shows the correct

complete source

 private func buildCircleSliderFoodQSlider() {
        self.circleSlider = CircleSlider(frame: self.FoodQSlider.bounds, options: self.sliderOptions)

        let delay = 0.1 * Double(NSEC_PER_SEC)
        let time  = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
        dispatch_after(time, dispatch_get_main_queue(), {
            self.circleSlider.value = Float(self.reviwesRoundTwo[0])
        })
        self.FoodQSlider.addSubview(self.circleSlider!)
        self.valueLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
        self.valueLabel.textAlignment = .Center
        self.valueLabel.center = CGPoint(x: CGRectGetWidth(self.circleSlider.bounds) * 0.5, y: CGRectGetHeight(self.circleSlider.bounds) * 0.5)
        self.valueLabel.text = String(reviwesRoundTwo[0])
        self.circleSlider.addSubview(self.valueLabel)
    }

hello how can look FoodQSlider ?

   @IBOutlet weak var FoodQSlider      : UIView!

private func buildCircleSliderFoodQSlider() {
        self.circleSlider = CircleSlider(frame: self.FoodQSlider.bounds, options: self.sliderOptions)

        let delay = 0.1 * Double(NSEC_PER_SEC)
        let time  = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
        dispatch_after(time, dispatch_get_main_queue(), {
            self.circleSlider.value = Float(self.reviwesRoundTwo[0])
        })
        self.FoodQSlider.addSubview(self.circleSlider!)
        self.valueLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
        self.valueLabel.textAlignment = .Center
        self.valueLabel.center = CGPoint(x: CGRectGetWidth(self.circleSlider.bounds) * 0.5, y: CGRectGetHeight(self.circleSlider.bounds) * 0.5)
        self.valueLabel.text = String(reviwesRoundTwo[0])
        self.circleSlider.addSubview(self.valueLabel)
    }
