title: MBProgressHUD with Table View how to hide HUD?
body: <p>well I have my RSS application running perfect, and now i'm trying to add some indicator with MBProgressHUD.</p>
  
  <p>I implement this code in the View Controller under ViewDidLoad</p>
  
  <pre><code> HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
  [self.navigationController.view addSubview:HUD];
  HUD.labelText = @"Loading";
  
  [HUD show:YES];
  </code></pre>
  
  <p>so far so good. the indicator is working but of course never disappearing.
  I am a newbie, I tried to add to my [HUD hide:yes] in certain parts of the implementation file but it's not working .
  how can I hide the indicator when the data finish to load ? 
  here is my implementation file. </p>
  
  <pre><code>    @implementation ListadoArticulosViewController
  
  - (void)viewDidLoad
  {
      [super viewDidLoad];
  
      // HUD setting 
  
      HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
      [self.navigationController.view addSubview:HUD];
      HUD.labelText = @"Loading";
  
      [HUD show:YES];
