title: UIView addSubview and the subview isn't displayed
body: <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      // Do any additional setup after loading the view from its nib.
      HeadViewController *headViewController = [[HeadViewController alloc] initWithNibName:@"HeadViewController" bundle:nil];    
      UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 120)];
      [view addSubview:headViewController.vew];
      [self.view addSubview:view];
  }
  </code></pre>
  
  <p>HeadViewController.h:</p>
  
  <pre><code>@interface HeadViewController : UIViewController
  {
      IBOutlet UIView *view;
  }
  @property (nonatomic, retain)IBOutlet UIView *view;
  @end
  </code></pre>
  
  <p>and I connect the view to the file's owner.</p>
