For generating PDF files we can use Core Graphics. Similarly is there any framework / class that can be used for generating .ppt (power point presentation) files via code ? Or is there any third party framework for this purpose.
There's no in-built Apple API, and I've never heard of a third-party framework for this.
Seems there are still no open source solutions for this for iOS platform. Aspose seems to have something and another commercial that pretty recently emerged - libpptx.com, at least it provides some generic functionality to craft pptx
