Question

我有一个矩形节点：

let shape = SKShapeNode()
shape.path = UIBezierPath(roundedRect: CGRect(x: -128, y: -128, width: 256, height: 256), cornerRadius: 64).CGPath
shape.position = CGPoint(x: CGRectGetMidX(frame), y:    CGRectGetMidY(frame))
shape.fillColor = UIColor.redColor()
shape.strokeColor = UIColor.blueColor()
shape.lineWidth = 10
addChild(shape)

如何仅向TopLeft和TopRight角添加20的边框半径？

Answer 1

使用此UIBezierPath初始化程序：

public convenience init(roundedRect rect: CGRect, byRoundingCorners corners: UIRectCorner, cornerRadii: CGSize)

并为[.TopLeft, .TopRight]参数指定byRoundingCorners。

shape.path = UIBezierPath(
    roundedRect: CGRect(x: -128, y: -128, width: 256, height: 256),
    byRoundingCorners: [.TopLeft, .TopRight]
    cornerRadii: CGSize(width: 64, height: 64)).CGPath
