ios - 在iOS中以波形切割 View

我正在尝试以编程方式创建如下所示的视图。我相信我将需要使用Beizer路径，但不确定如何处理路径点？任何帮助表示赞赏

func createShape() -> UIBezierPath {

    // create a new path
    let path = UIBezierPath()

   //Need to determine path points here
}

最佳答案

对于您需要的形状，请参考波纹管代码，希望它将对您有所帮助

 let view = UIView(frame: CGRect(x: 50, y: 100, width: 200, height: 300))

        let path = UIBezierPath()
        path.move(to: CGPoint(x: 0.0, y: 200))
        path.addCurve(to: CGPoint(x: 200, y:150),
                      controlPoint1: CGPoint(x: 50, y: 350),
                      controlPoint2: CGPoint(x:150, y: 0))
        path.addLine(to: CGPoint(x: view.frame.size.width, y: view.frame.size.height))
        path.addLine(to: CGPoint(x: 0.0, y: view.frame.size.height))
        path.close()

        let shapeLayer = CAShapeLayer()
        shapeLayer.path = path.cgPath

        view.backgroundColor = UIColor.black
        view.layer.mask = shapeLayer
        self.view.addSubview(view)

这是我的输出
