on view load, start a timer and reveal images at times in iPad app

So in my XIB I have a few graphics that need to reveal in order.. say every one second, the next开发者_开发技巧 thing will reveal.. I assume I am going to need something involving viewdidload, starting an NSTimer, then animate the revealing of my graphics with the timer. Can anyone please drop me a few ideas, hints or lines of code to get started?

Thanks!

You could use Quartz Composer to build your image sequence, and then render that to a QCView or OpenGL context.
