title: Correct way to save/serialize custom objects in iOS
body: <p>I have a custom object, a <code>UIImageView</code> subclass which has a few <code>gestureRecognizer</code> objects. </p>
  
  <p>If I have a number of these objects stored in a <code>NSMutableArray</code>, how would this array of objects be saved to disk so that it can be loaded when the user runs the app again?</p>
  
  <p>I would like to load the array from the disk and use the objects.</p>
