title: Making a screen which only appears once and never comes again
body: <p>I was wondering if there was a way in which a sort of how-to use the app guide would come up and show how to use the app the first time and when the person closes guide it never comes again.</p>
  
  <p>Like some apps have a start image that show how to use the app. I want to make this and when the person closes the image, I want this image to never come again. Even after the app closes.</p>
  
  <p>I use storyboards so I don't need to make this programatically, but I can. Can someone please write the code or tell me how to do this?</p>
