Since this is 09' answers and whatnot I figure I update the link and code here for anyone looking in 11'.

The link for the Quartz Demo is: http://developer.apple.com/library/ios/#samplecode/QuartzDemo/Introduction/Intro.html

and the code I use to draw multiple lines is:

   //Drawing lines

    // Set the color that we want to use to draw the line
[ [ UIColor brownColor] set];

    //Get the current graphics context (pen)
CGContextRef currentContext = UIGraphicsGetCurrentContext();

    // Set the width for the line 
CGContextSetLineWidth(currentContext,
                      5.0f);

    // Start the line at this point
CGContextMoveToPoint(currentContext,
                     20.0f,
                     20.0f);
    // And end it at this point 
CGContextAddLineToPoint(currentContext,
                        100.0f,
                        100.0f);

    // Extend the line to another point
CGContextAddLineToPoint(currentContext,
                        300.0f,
                        100.0f);


    //Use the context's current color to draw the line
CGContextStrokePath(currentContext);

I recommend reading Graphics and Animation on iOS: A Beginner's Guide to Core Graphics and Core Animation by Vandad Nahavandipoor. It's mostly on graphics than animation though. I recommend checking out his videos on animation if your interested. http://www.youtube.com/watch?v=ybMFPB-Gbsw&feature=player_embedded They're called Animations in iOS using Block Objects Part I and II. Supposedly there are supposed to be more videos at some point. But the videos go with the book.

That's it.
