I have a chartView and a customized tableViewcell.

And I try to use chartView add on my tableviewcell.

This ViewController is child ViewController.

I push to this ViewController, and I want to call tapIndexAction(index: 0) to hightlight my bar of index 0.

I also use "tableview didEndDisplaying" can't fill color.

What's wrong with me?

Thanks.

class ChartView: UIView {



let publishSub = PublishSubject<Int?>()

var isAlreadyInit = false

var chartInfo:ChartInfo?



init(info:ChartInfo?, frame:CGRect = CGRect.zero) {

    self.chartInfo = info



    super.init(frame:frame)

}



required init?(coder aDecoder: NSCoder) {

    fatalError("init(coder:) has not been implemented")

}



override func layoutSubviews() {

    super.layoutSubviews()



    if !self.isAlreadyInit {

        if self.frame.width > 0 {

            self.isAlreadyInit = true



            self.drawChart()

        }

    }

}



func drawChart() {

    if let tmpCharInfo = self.chartInfo {

        let chartLayer = tmpChartInfo.getChartDrawLayer()

        chartLayer.frame = self.bounds



        chartLayer.drawChart()



        self.layer.addSublayer(chartLayer)

    }

}



func tapIndexAction(index: Int) {



    if let chartLayer = (self.layer.sublayers?.last) as? ChartLayer {

        chartLayer.tapIndex(index: index)

        self.publishSub.onNext(index)

    }

}





class ChartLayer: CALayer {



    var drawInfo:ChartInfo

    var touchFrame:[CGRect] = [CGRect]()

    var drawLayers:[CAShapeLayer] = [CAShapeLayer]()

    var tapIndex:Int?





    init(info:ChartDrawInfo) {

        self.drawInfo = info



        super.init()

    }



    required init?(coder aDecoder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }



    func tapIndex(index:Int) {

        self.tapIndex = index



        for idx in 0..<self.touchFrame.count {

            let shapeLayer = self.drawLayers[idx]



            if idx == index {

                shapeLayer.fillColor = UIColor.red.cgColor  //Not work in "tableview didEndDisplaying"          

            }else {

                shapeLayer.fillColor = UIColor.blue.cgColor

            }

    }





}

        var barChartView: ChartView?

        var chartInfo:ChartInfo?



        func initCell(drawInfo: ChartInfo?) {



            self.chartInfo = drawInfo



            if self.barChartView != nil {



                for view in self.contentView.subviews {

                    view.snp.removeConstraints()

                    view.removeFromSuperview()
