title: iOS - UIImageView slight glitch
body: <p>I have a myriad of <code>UIImageViews</code> that act as 'tiles' on a map.  They align up next to one another to form a grid of images.</p>
  
  <p>Ordinarily, the grid images are flush against each other, but whenever the iPhone or iPad device is rotated, or if a <code>UIView</code> is applied to the view that contains these tiles, the spaces between the <code>UIImageViews</code> become momentarily visible, showing off the grid pattern that I'd like to be invisible.</p>
  
  <p>Any ideas what might be causing this?</p>
  
  <p>Thanks </p>
