title: How can I set a UIView to hidden in Xamarin
body: <p>I am building my first app with Xamarin. I created a UIView called reord_overlay. I want to set it to hidden after ViewDidLoad:</p>
  
  <pre><code>record_overlay.Hidden = true;
  </code></pre>
  
  <p>What I get is an error about the </p>
  
  <pre><code>../VoYo/iOS/ViewController.designer.cs(27,27): Error CS0102: The type `VoYo.iOS.ViewController' already contains a definition for `recording' (CS0102) (VoYo.iOS)
  </code></pre>
  
  <p>How can I set the view to be hidden?</p>
  
  <p>The error says it is in my ViewController.designer.cs file:</p>
