title: iOS 5 Location of Objects on Screen
body: <p>I am creating a test app that will add multiple UIImageViews with images. The user will be able to move and rotate these images around. I have the UIGestureRecognizers in place and working, but I need to also keep track of the location of where the user leaves the images on screen. That way if they close the app and come back, where they placed the images will be remembered. </p>
  
  <p>I know I should be using NSUserDefaults for this, but my question is how do I keep track of possibly a very large amount of UIImageView's locations on screen. I assume I need to somehow get the x/y coordinates of them and store that with NSUserDefaults. </p>
  
  <p>Anyone have suggestions of how to do this?</p>
