I'm trying to build the code that will generate a single PDF from a bunch of images in Objective-C. Most of examples I've seen so far don't really allow me to build the PDF, but only generating Cocoa views and turning them into PDFs.

What I'm looking for is some toolkit (like Java's iText) that would allow me to generate a PDF from a bunch of images (with each image being a page in the PDF document).

Any hints?
