title: MBProgressHUD delegate hudWasHidden not called
body: <p>I use MBProgressHUD in my iPhone app. Everything works fine, I display alerts as I want. But there's an issue : I can't use the <code>hudWasHidden</code> delegate for one of my alerts. I want to do this because I use a custom segue to load a view from another, but I want to load the view only after the alert hid. I call the alert that way : <code>[alertSentHUD hide:YES afterDelay:2.0];</code> and I've set my class to be a <code>MBProgressHUDDelegate</code> (in the header file). I also put <code>[alertSentHUD setDelegate:self];</code> in my viewDidLoad, in order to catch the <code>hudWasHidden</code> in question, where I launch my segue as I usually do : <code>[self performSegueWithIdentifier:@"NewAlertToAllThreads" sender:self];</code>.</p>
  
  <p>But it seems like this is never called (I don't get to the view I want).</p>
  
  <p>Any ideas ? Thanks.</p>
