title: Determining the available amount of RAM on an iOS device
body: <p>You've likely seen the many "System Info" apps out there which display things like remaining battery life, and even system info like memory, etc. </p>
  
  <p>In a similar manner, is there any way to retrieve the current amount of available RAM from my app so that I can make better decisions on when it's best to dump or keep certain views to avoid memory warnings?</p>
