Create a straight line with SpriteKit

How can I create a straight line using SpriteKit and UITouch?

I wanted a method that allowed me to add the start point and the end point instead of a path. Just like a rubber band.

  1. Create a SKShapeNode that is a line when user begins the touch movement e.g. in touchesBegan:.

    SKShapeNode *line = [SKShapeNode node];
CGPoint startPoint = CGPointMake(..., ...)
CGPoint endPoint = CGPointMake(..., ...)

CGMutablePathRef pathToDraw = CGPathCreateMutable();
CGPathMoveToPoint(pathToDraw, NULL, startPoint.x, startPoint.y);
CGPathAddLineToPoint(pathToDraw, NULL, endPoint.x, endPoint.y);

line.path = pathToDraw;
line.strokeColor = [UIColor redColor]];
[self addChild:line];

  2. Modify its path to change its length in touchesMoved:
