title: Where do I put logic for when an iOS application hard closes and comes back?
body: <p>I have an iOS application where I need to persist a set of data after the application HARD CLOSES (when the user double clicks the Home button and slides the application upwards). Then, when the application comes back to the foreground, I need to fetch that data and do something with it. I'm just not sure where I need to put that logic for Application Hard Close and Resuming the Application.</p>
