title: Disable all buttons until finished loading?
body: <p>I have a app where people can delete stuff. I am wanting to disable all my buttons so the user has to wait till the action is done.</p>
  
  <p>I have the setHidesBackButton working, but it looks tacky. I would rather have it just become inactive where if the user taps it, they can't go anywhere. </p>
  
  <p>I have looked into a few things, and wonder what's the best option! (like to replace it with another button).</p>
  
  <p>Please post some code with your answer :)</p>
  
  <p>Thanks in advance,<br>Coulton</p>
