title: What's the difference between height and maxY, and width and maxW?
body: <p>From the Apple Documentation, the maxY of a view is</p>
  
  <blockquote>
    <p>The largest value for the y-coordinate of the rectangle.</p>
  </blockquote>
  
  <p>The maxX of a view is</p>
  
  <blockquote>
    <p>The largest value of the x-coordinate for the rectangle.</p>
  </blockquote>
  
  <p>Also from the Apple Documentation, the width of a view is</p>
  
  <blockquote>
    <p>The width of the specified rectangle.</p>
  </blockquote>
  
  <p>The height of a view is</p>
  
  <blockquote>
    <p>The height of the specified rectangle.</p>
  </blockquote>
  
  <p>If the view being specified took up the whole screen, then what would be the difference between these properties, and when should I use each?</p>
