title: How do I create a 1px line in Interface Builder?
body: <p>Note, I'm looking to make a 1px line, not a 1pt line.  Meaning it should be 1px regardless of screen scale (so 0.5pt on Retina devices).</p>
  
  <p>I can do this programmatically, but can I do it in the Interface Builder?  For example I cannot set a UIView to have a height of less than 1.</p>
  
  <p>If I can do it in IB then I don't have to declare an outlet and manually set the frame in <code>awakeFromNib</code>.</p>
