I want to create a slideshow on iphone. I don't know if there is already a sample code or a lib that already do that.

Thanks for your help

Joe Hewitt who created the Facebook iPhone app open sourced the code he wrote to create the Facebook application. Most notable is his image viewer that he created. I am certain if you checkout his work you can find what you are looking for. His project lives on github.

Reference to his work from his website:

Check out the WWDC 2010 Session entitled "Designing Apps with Scroll Views."

The source code is here:

And this is a handy image-slicing tool:

If you just want to show different pictures one by one, you can simply use, for example, NSTimer, that will change content of your image view. It doesn't need any lib.
