title: What is wrong with my code? I'm using MBProgressHUD
body: <p>I'm using <strong>MBProgress HUD</strong> and I don't know what is the problem.
  I have a <code>UIButton</code> that shows the <strong>HUD</strong>.
  This is my code:</p>
  
  <pre><code>- (void)showHUD:(id)sender {
      HUD = [[MBProgressHUD alloc] initWithView:self.view];
      HUD.mode = MBProgressHUDModeCustomView;
      [self.view addSubview:HUD];
      HUD.delegate = self;
      HUD.labelText = @"No Internet Connection...";
      HUD.opacity = 0.7;
      HUD.customView = 
       [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]];
      [HUD showWhileExecuting:@selector(hudWasHidden) 
                     onTarget:self 
                   withObject:nil 
                     animated:YES];
  }
  
  
  - (void)hudWasHidden {
  
      float progress = 0.0f;
      while (progress &lt; 1.0f) {
          progress += 0.01f;
          HUD.progress = progress;
          usleep(50000);
      }
  }
  </code></pre>
  
  <p>Here is the Console log:</p>
