title: Clear Label text used in Storyboard
body: <p>Wondering if anyone know hows to complete the following...</p>
  
  <p>In a <code>Storyboard</code> I set my Labels with dummy text, they are not Static text. For example 'User1 Username'.  </p>
  
  <p>What I would to know if there is a setting to clear the value of this label when it is loaded by the view. I have some other code that runs off and collects the relevant information. However, it might take a few seconds so a HUD is shown to the user whilst it loads.  </p>
  
  <p>Of course in the background of the HUD you can see the example text shown. I know in <code>viewDidLoad</code> I could simply clear all the label texts setting them back to <code>@""</code>, but is there no setting in the storyboard or anything for this?</p>
