我尝试使用 UIBezietPath 绘制形状，但每次我都遇到“曲线”问题。为了解决我的问题，我确实使用了 Paint Code，代码生成得很好，但它是一个静态形状，我尝试将此代码转换为动态屏幕尺寸，但每次我都遇到一半形状的问题。

谁能帮我正确翻译这段代码？

Paint Code 生成的代码：

//// Color Declarations
let fillColor = NSColor(red: 0.118, green: 0.118, blue: 0.149, alpha: 1)

//// Bezier Drawing
let bezierPath = NSBezierPath()
bezierPath.move(to: NSPoint(x: 8.83, y: 89))
bezierPath.line(to: NSPoint(x: 154.29, y: 89))
bezierPath.curve(to: NSPoint(x: 163.01, y: 81.04), controlPoint1: NSPoint(x: 158.71, y: 89), controlPoint2: NSPoint(x: 162.21, y: 85.39))
bezierPath.curve(to: NSPoint(x: 206.45, y: 45.05), controlPoint1: NSPoint(x: 166.77, y: 60.57), controlPoint2: NSPoint(x: 184.79, y: 45.05))
bezierPath.curve(to: NSPoint(x: 249.89, y: 81.04), controlPoint1: NSPoint(x: 228.11, y: 45.05), controlPoint2: NSPoint(x: 246.12, y: 60.57))
bezierPath.curve(to: NSPoint(x: 258.61, y: 89), controlPoint1: NSPoint(x: 250.68, y: 85.39), controlPoint2: NSPoint(x: 254.19, y: 89))
bezierPath.line(to: NSPoint(x: 405.17, y: 89))
bezierPath.curve(to: NSPoint(x: 414, y: 80.21), controlPoint1: NSPoint(x: 410.05, y: 89), controlPoint2: NSPoint(x: 414, y: 85.06))
bezierPath.line(to: NSPoint(x: 414, y: 8.79))
bezierPath.curve(to: NSPoint(x: 405.17, y: 0), controlPoint1: NSPoint(x: 414, y: 3.94), controlPoint2: NSPoint(x: 410.05, y: 0))
bezierPath.line(to: NSPoint(x: 8.83, y: 0))
bezierPath.curve(to: NSPoint(x: 0, y: 8.79), controlPoint1: NSPoint(x: 3.95, y: 0), controlPoint2: NSPoint(x: 0, y: 3.94))
bezierPath.line(to: NSPoint(x: 0, y: 80.21))
bezierPath.curve(to: NSPoint(x: 8.83, y: 89), controlPoint1: NSPoint(x: 0, y: 85.06), controlPoint2: NSPoint(x: 3.95, y: 89))
bezierPath.close()
fillColor.setFill()
bezierPath.fill()

首先扩展CGPoint并创建一个scaled(by:)方法：

extension CGPoint {
    func scaled(by value: CGFloat) -> CGPoint { applying(.init(scaleX: value, y: value)) }
}

然后获取实际超级视图的bounds宽度并除以路径的宽度414。

let value: CGFloat = superview!.bounds.size.width / 414

现在您只需要将比例值应用于路径的每个点：

bezierPath.move(to: NSPoint(x: 8.83, y: 89).scaled(by: value))
