title: Interface Bulder and XCode: change color of a view "top bar"
body: <p>I have a couple of views in my iPhone app.
  each view shows a "top bar" in blue, I haven't added a "Navigation Bar", simply edited what's on the inspector "View Controller" section and gave it a title. (this section: <a href="http://img69.imageshack.us/i/schermata20101001a22014.png/" rel="nofollow">http://img69.imageshack.us/i/schermata20101001a22014.png/</a>)</p>
  
  <p>Is it possible to change the color of this bar that'a automatically added on top of other View Items? or even to hide it? both In Interface Builder or in Code,
  thanks.</p>
