so i'm just starting to learn about programming for the iphone. was a web developer a long time ago, but this is my first with a mac environment, so forgive my crazy crazy questions. i've dl'd the apple example "UICatalog", but I can't get it to compile. The #import "SourceCell.h" line gives me an error, saying it can't find the file. I do see the file in the project. am i missing something here? thanks.
