I have a web-service that transforms an uploaded pdf into a flipping-book. I wan't to create an iOS app that allows the user to upload their pdf and recieve the flipping-book. What possibilities are there to upload pdf from iPhone/iPad ?
Is it possible via iCloud? Are there any other options?
You can probably register your app to open pdf files from whatever sources (like from mail attachments), here's an example of how it is done: how to register the app to open the pdf file in my app in ipad
