title: Xcode 6: How to make an image view fill the screen on all devices? Auto layout not working?
body: <p>So I have an image view and a button. I need the image view to be the correct size (not look squished or stretched) on all devices and more importantly I need it to be the size of the screen. I need the button to stay in about the same place on all devices. </p>
  
  <p>Back with Xcode 5 I remember auto layout fixing this problem but now that does not work. I looked at <a href="https://www.youtube.com/watch?v=G53PuA_TlXk" rel="noreferrer">https://www.youtube.com/watch?v=G53PuA_TlXk</a> and tried control-dragging to the view controller and centering the view both horizontally and vertically, but I can't get it to scale to the size of the screen. The video doesn't address this. </p>
  
  <p>Is there a specific option I need to choose when control-dragging to keep the image view scaled? What should I do? </p>
