推荐答案

Using SKShapeNode 你可以画线或任何形状.

Using SKShapeNode you can draw line or any shape.

SKShapeNode *yourline = [SKShapeNode node];
CGMutablePathRef pathToDraw = CGPathCreateMutable();
CGPathMoveToPoint(pathToDraw, NULL, 100.0, 100.0);
CGPathAddLineToPoint(pathToDraw, NULL, 50.0, 50.0);
yourline.path = pathToDraw;
[yourline setStrokeColor:[SKColor redColor]];
[self addChild:yourline];

相当于 Swift 4:

var yourline = SKShapeNode()
var pathToDraw = CGMutablePath()
pathToDraw.move(to: CGPoint(x: 100.0, y: 100.0))
pathToDraw.addLine(to: CGPoint(x: 50.0, y: 50.0))
yourline.path = pathToDraw
yourline.strokeColor = SKColor.red
addChild(yourline)
