绘制圆角线条iOS Swift

import UIKit

class RoundedLineView: UIView {
    override func draw(_ rect: CGRect) {
        // 创建圆角路径
        let path = UIBezierPath(roundedRect: bounds, cornerRadius: 10)
        
        // 创建CAShapeLayer
        let shapeLayer = CAShapeLayer()
        shapeLayer.path = path.cgPath
        
        // 设置线条颜色和宽度
        shapeLayer.strokeColor = UIColor.red.cgColor
        shapeLayer.lineWidth = 2.0
        
        // 将CAShapeLayer添加到UIView的layer中
        layer.addSublayer(shapeLayer)
    }
}

let roundedLineView = RoundedLineView(frame: CGRect(x: 100, y: 100, width: 200, height: 200))
view.addSubview(roundedLineView)
