title: Equivalent of dynamic type "automatically adjusts font" setting for UIButton in Interface Builder?
body: <p>A UILabel has a <code>Dynamic Type: Automatically Adjusts Font</code> check-box in the Attributes Inspector in Interface Builder.</p>
  
  <p>Is there an equivalent in Interface Builder for automatically adjusting the font size of a UIButton, or does this have to be handled in code?</p>
  
  <p>I'm using Xcode 9.0 beta 6, targeting iOS 11.</p>
