I've read that ios apps can communicate via unique urls. An online tutorial on tutsplus says
Communication between apps provides your application with an opportunity to take advantage of other application’s functionality, send and receive data between apps, and provide a rich user experience that “just works”.
I have to admit that since I have no experience with objective c and cocoa I only scanned the article. But as far as I've understood the url based communication, your app can register a unique url that serves as a socket for communication.
Is this not the perfect basis for a crude file system ? I know that all ios apps run in a sandbox and can only access their own data. I do recognose the merits of this design decision but still it seems cure and curse at the same time. This is not meant to be a discussion about apple's ecosystem and the concept of ios apps.
My question is simply:
Can url communication be used to create a file storage that works like a simple "desk" ? I would love an app that could store and host my files to allow a simpler workflow between different apps. Is this technically possible or did I misunderstand the url system ? Would apple allow an app like this in the app store ?
