Reading powerpoint pptx file in Objective-C

Question

I was asked to find a way to use pptx as input for a game using cocos2D on iphone. As far as I know pptx file use Office Open XML standard and should be fully readable, including informations on animations, in any programming language.

However I only find examples/tutorial using docx files and I would like to know if such documentation exists for pptx files.

I just spent two days on that topic, and I just can't find the strength to dive into Microsoft documentation.

A .pptx file is just a ZIP file containing some images files and XML files. Wouter van Vugt's free e-book will help you understand the XML. Unfortunately the files contain a lot of boilerplate so it can take some time to find the bits you are interested in.
