title: iOS - "Clean memory" or "Free memory" : how to do it
body: <p>I've an app on the App Store that monitor the system status. My users require a Free Memory button to clean the RAM. I know that iOS manages the memory as OS X, so the inactive memory, practically, is free memory, right? Simply the inactive memory helps to run quickly some recent applications. In iOS how can I do a clean for the memory? I see a lot of apps do it, but how?</p>
