swift - 堆叠式进度指示器 swift

Question

我如何创建一个堆叠式进度指示器，以便与存储管理中的界面构建器一起使用？

有没有类似的cocoa控件？

如果没有，我是否应该尝试创建一个自定义 View ，在女巫中，每次我调用类似 progress.add(width: 10.0, color: NSColor(.. .))?

我刚刚做了一个绘制 View 的函数，你可以玩一下。

func drawStackedProgress(percentages:[Float], width:Float, height:Float, x:Float, y:Float){
        var currentX = x

        // I just threw a bunch of random (mostly probably ugly) colors in this array. Go ahead and make sure there's as many colors as stacked elements.
        var colors = [UIColor.red, UIColor.blue, UIColor.green, UIColor.brown, UIColor.cyan]
        var index = -1
        for percentage in percentages{
            index += 1
            let DynamicView=UIView(frame: CGRect(x: CGFloat(currentX), y: CGFloat(y), width: CGFloat(Double(percentage)*Double(width)), height: CGFloat(height)))
            currentX+=Float(Double(percentages[index])*Double(width))
            DynamicView.backgroundColor=colors[index]
            self.view.addSubview(DynamicView)
        }

    }

实现:

drawStackedProgress(percentages: [0.1,0.3,0.5,0.1], width: 200, height: 20, x: 200, y: 200)
