title: How to make iPhone application go to pause menu when home button is clicked?
body: <p>I am making an iPhone application that is fairly simple.  All I need to do is set the bool "paused" to true to pause the game.  How can I make my application do that when the home button is hit?</p>
  
  <p>Thanks guys, that was exactly what I wanted.  Since it is in the appDelegate, though, I can't access the boolean "paused" to change it.  How can I make it global so that I can access it from the appDelegate?</p>
