AudioKit如何更新绘图以更改颜色或原型

import AudioKit
import UIKit

class CustomDrawingView: UIView {
    var shapeColor: UIColor = .red
    var shapePath: UIBezierPath = UIBezierPath(rect: CGRect(x: 0, y: 0, width: 100, height: 100))
    
    override func draw(_ rect: CGRect) {
        super.draw(rect)
        
        // 绘制图形
        shapeColor.setFill()
        shapePath.fill()
    }
    
    func updateShapeColor(_ color: UIColor) {
        shapeColor = color
        setNeedsDisplay()
    }
    
    func updateShapePath(_ path: UIBezierPath) {
        shapePath = path
        setNeedsDisplay()
    }
}

// 在使用的地方创建和使用CustomDrawingView
let customView = CustomDrawingView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
customView.updateShapeColor(.blue)
customView.updateShapePath(UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: 200, height: 200)))
