title: Saving a Single int into NSdefaults
body: <p>I've been searching around for tutorials on how to save certain things to NSuserdefaults but have only found stuff mostly dealing with arrays and strings. Can anyone lead me to or give some person knowledge about saving and loading a int. For my application I have my int highScore = 0; but I want it to save this int into your NSuserdefaults so when my game loads back up it displays your current high score you recently achieved.</p>
