title: Trying to set tabBarController translucent. But not working. Alpha can be set
body: <p>I'm using the standard code for setting up my TabBarController, but I can't for the life of me get it to be translucent. I overlay a view with my TabBarController, I would like that image to show through the TBC. Actually I want the bar to just fade away like the Photo app does after a few seconds, but for now, one step at a time.  Translucent first. thanks </p>
  
  <pre><code>- (void)applicationDidFinishLaunching:(UIApplication *)application 
  { 
  
   tabBarController = [[UITabBarController alloc] init]; 
  
   //tabBarController.tabBar.barStyle = UIBarStyleBlackTranslucent;
  
   //ERROR: request for member in something not a structure of member
  
   //BUT this will work! But just affects the alpha value
  
   tabBarController.tabBar.alpha = .5;
  
   view1Controller = [[View1Controller alloc] init];  
   view2Controller = [[View2Controller alloc] init]; 
   view3Controller = [[View3Controller alloc] init]; 
  
   tabBarController.viewControllers = [NSArray arrayWithObjects:view1Controller, view2Controller, view3Controller, nil];  
  
   [window addSubview:tabBarController.view]; 
   [window makeKeyAndVisible]; 
  }
  </code></pre>
