If it is cocos2d like in ur tag, here it is..

Under any CCLayer, overwrite the draw function.. Means you declare your own draw function.. Note that the line drawn will be at z:0.

If you have any other addchild on the layer, make sure that their z are less than 0.. Meaning.. [self addChild:spr z:-1]; Else you will not see the line..

Here's the codes:

-(void)draw{
glColor4f(0.8, 1.0, 0.8, 1.0);  
glLineWidth(10.0f);
drawLine(xStartPoint,yStartPoint,xEndPoint,yEndPoint);
}
