How to select a CAShapeLayer

Question

Using that code I'm creating a line from the first touch (touches began) and the last (touchEnded). But to make this shape dynamic (resize and move) I need to select it when I touch it. How can I do that?

    shape.opacity = 1
    shape.lineWidth = 2
    shape.lineJoin = kCALineJoinMiter
    shape.strokeColor = UIColor.blackColor().CGColor
    shape.fillColor = UIColor.blackColor().CGColor


    path.moveToPoint(firstPoint)
    path.addLineToPoint(touchEnded)
    shape.path = path.CGPath

    drawView.layer.addSublayer(shape)

您可以使用手势识别器，然后将坐标传递给containsPoint（）来查看您是否正在与形状进行交互。
