I fount this solution but I can’t make it into swift code

这就是我的尝试

var pattern[2]:CGFloat; this 

var dashed: CGPathRef = CGPathCreateCopyByDashingPath(CGPathCreateCopyByDashingPath(path,transform,phase,lengths,count);

var myShapeNode: SKShapeNode!;

        var CGPathCreateCopyByDashingPath:CGPathRef;

解决方法

这是你在swift中绘制虚线的方法.您可以根据需要更改参数.

let bezierPath = UIBezierPath()
let startPoint = CGPointMake(0,250)
let endPoint = CGPointMake(450,250)
bezierPath.moveToPoint(startPoint)
bezierPath.addLineToPoint(endPoint)

var pattern : [CGFloat] = [10.0,10.0]
let dashed = CGPathCreateCopyByDashingPath (bezierPath.CGPath,nil,pattern,2)

var shapeNode = SKShapeNode(path: dashed)
shapeNode.position = CGPointMake(100,100)
self.addChild(shapeNode)
