title: How to detect when the phone has been put down
body: <p>I would like an action to take place when the phone is stationary for 2 seconds. I've searched for ages around google and stack overflow. I discovered that "Accelerometer DidAccelerate" has been depreciated and that CoreMotion is the replacement. Everything I have seen has been to do with the 'shaking' motion. I've tried reading through apple's documentation but It just confuses me!</p>
  
  <p>Basically, I want the app to detect that the g-forces on the phone have remained within a small limit for a certain amount of time (suggesting that the phone has been laid down on a table or something) and for it to call and instance or make the app do something.</p>
  
  <p>Any help would be greatly appreciated.</p>
