UIBezierPath不规则图形小记

  UIBezierPath *path = [UIBezierPath bezierPath];

        CGFloatvh =Get375Height(56);

        [pathmoveToPoint:CGPointMake(0, 0)];

        [pathaddLineToPoint:CGPointMake(0, vh)];

        [pathaddLineToPoint:CGPointMake(kScreenWidth, vh)];

        [pathaddLineToPoint:CGPointMake(kScreenWidth, vh/3*2)];

        [pathaddQuadCurveToPoint:CGPointMake(kScreenWidth - 100, vh) controlPoint:CGPointMake(kScreenWidth, vh)];

        [pathaddQuadCurveToPoint:CGPointMake(0, 0) controlPoint:CGPointMake(kScreenWidth/5, vh)];

        CAShapeLayer*shapLayer = [CAShapeLayerlayer];

        shapLayer.path= path.CGPath;

        self.bezierView.layer.mask= shapLayer;

[self.view addsubview : self.bezierView];

注解：        [pathaddQuadCurveToPoint:CGPointMake(0, 0) controlPoint:CGPointMake(kScreenWidth/5, vh)];

CurveToPoint是终点  起点在上一个终点   controlPoint是起点和终点的弧度的最高点或是最低点（个人是这样理解的）

大概就这样
