Before going all the hassle coding a generic asynchronous, queued, background running file download library with pause, resume and cancel features, I was wondering if is it possible using some of the already available similar features of NewsstandKit.framework
in a non–Newsstand app and publish it on the App Store?
In case the answer is not a plain "no", I would like to know which features would be okay using.
The answer is unfortunately, no.
Also, you're not going to get background downloading unless you are using Newsstand. They're the only apps allowed to download whilst the app is not open.
