sample code

[patndan]

hi - being a neophyte to the ipad, but not programming itself, I was wondering, before I go and reinvent the wheel, if there is any sample code about I can use or review that will deal with a rather simple project. I have 28 png images (landscape mode) that i want to display and change each time a user touches a button... as the ipad can rotate, i imagine (if the image needs to be adjusted to display between the horizontal and vertical displays), I will need to have a second set of the same png images to display them in portrait.... if there is anything out there that someone can direct me to, i would be appreciative. Meanwhile, I will be reviewing the coding books I bought to see if there is something there I can use ... thanks in advance ... d
