title: How do I save user preferences for my iPhone app?
body: <p>The question title pretty much gives it away - I'd like my app to remember a few things. It's some sort of calculator, so it should save the last used values and some user selectable settings.</p>
  
  <p>Basically I'd like to save a handful of floats and BOOLs and load them again the next time the app loads.</p>
  
  <p>What's the best and easiest way to do that?</p>
  
  <p>Thanks!!</p>
