title: UIBarButtonItem with UIImage Always Tinted iOS 7
body: <p>I'm trying to add a <code>UIBarButtonItem</code> containing a <code>UIImage</code> to a <code>UIToolbar</code>.  The image keeps being tinted and I can't get it to show as the original colored image - all I want to do is display an image, verbatim, in a <code>UIBarButtonItem</code>!  I'm following the directions in the iOS 7 transition guide to set the image rendering mode to <code>UIImageRenderingModeAlwaysOriginal</code>.</p>
  
  <pre><code>UIImage *image = [UIImage imageNamed:@"myImage.png"];
  image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
  
  UIBarButtonItem *ratingImage = [[UIBarButtonItem alloc] initWithImage:image style:UIBarButtonItemStyleBordered target:nil action:nil];
  
  [toolbar setItems:[NSArray arrayWithObjects:ratingImage, nil] animated:YES];
  </code></pre>
  
  <p>One thing to note is that I set the tintColor for the main UIWindow of my app right when it loads...maybe this isn't important with regard to my issue, but thought I'd mention it.</p>
