I want to add free subscriptions to a newsstand app i've been working on, the only problem I can find out how to do this is from this guide. However as helpful as that is you have to use urban airship, where it cost $0.10 per subscribe, so for a free app, it'd be costing me, which i couldn't afford to do every month.
Are there any other ways; How would i set up a server my self? Would it be the same for any IAP stuff?
Thank you in advance.
Apple requires that Newsstand apps offer its contens using iTunes managed subscriptions. This means you have to run a server that hosts the Newsstand content, which won't be free.
Your only alternative is to release your app as a non-Newsstand app, build the content into your app, and release an App Store update when it's time for a new issue. This isn't ideal as only Newsstand apps have background downloading.
So... get some funding, or find someone else with a Newsstand app who will host your content for free :)
