title: adding a background image to UITabBarController
body: <p>This is what I have from googling, but evidently it's not what I need:</p>
  
  <pre><code>- (void)applicationDidFinishLaunching:(UIApplication *)application 
  {    
  // add the tab bar controller to the window
  
  [window addSubview:[tabBarController view]];
  
  // load the image, create a view with the image
  
  NSString* dirPath = [[NSBundle mainBundle] bundlePath];
  NSString* imageFile = [dirPath stringByAppendingString:@"homebackground.png"];
  UIImageView* view = [[UIImageView alloc] initWithImage: [UIImage imageNamed:imageFile]];
  
  [[tabBarController tabBar] addSubview: view];
  }
  </code></pre>
  
  <p>Yes, the image file loads fine..I think what the above does is attempt to change the bg of the navigation bar area of the tab bar? I'm not certain.</p>
  
  <p>Does anyone know how I would go about changing the actual background with an image?
  Thank you!</p>
