title: iOS - [UIColor clearColor] and UIToolbars
body: <p>I've been attempting to use <code>[UIColor clearColor]</code> with <code>UIToolbar</code> in an attempt to make a custom control interface more fitting of a "Mechanical" application (Think buttons you would see in a Movie from the 70s). </p>
  
  <p>What is happening is that when I set the toolbar to clearColor it is turning it matte black. The image behind it is red, tan and black so I'm sure it's not working as intended.</p>
  
  <p>One difference I see is that I'm using the toolbar on a nav controller and not a stand alone <code>UIToolbar</code>.</p>
  
  <p>The lines of code are</p>
  
  <pre><code>self.navigationController.toolbar.translucent = YES;
  self.navigationController.toolbar.backgroundColor = [UIColor clearColor];
  </code></pre>
  
  <p>and my upper navigation bar (that is setup in another view) is <code>UIBarStyleBlackTranslucent</code>, could this be throwing it off?</p>
  
  <p>any help tracking this down would be great.</p>
