I want to convert HTML to PDF on an iOS Device... ...but I dont want to load my HTML in a UIWebView, take a snapshot and generate an ugly PDF from this snapshot picture...because the text must be selectable for my purpose. I wonder how Apps like Save2PDF or Adobe® CreatePDF are able to converting multiple files into PDF and save them. I guess they don't generate the PDF's by their own, but get them from Apples Printing Framework. How does this Apps work?
