title: NSNotification not being received in a UIViewController whose view is a subview of a UIScrollview
body: <p>I'm trying to subscribe myViewController to a custom NSNotification. The view heirarchy looks like this:</p>
  
  <pre><code>
  window
     - rootViewController.view
        - scrollView
            - myViewController.view
  
  </code></pre>
  
  <p>The notification is being sent to the [NSNotificationCenter defaultCenter] from a button inside the rootViewController's view. The rootViewController listens for the notification and responds to it just fine.</p>
  
  <p>I have the same exact "listening" code inside myViewController, but it's not receiving the notification for some reason. If it's part of the app it should receive the notification, correct? I have a debug message inside myViewController's initWithNibName method, so I know that it's subscribing to the notification. I even tried having myViewController listen for ALL notifications by setting the notification name to nil. For example:</p>
  
  <pre><code>
  NSLog(@"main view controller initialized");
  
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarVisibilityChanged:) name:nil object:nil];
  
  </code></pre>
  
  <p>But no luck there either. Has anyone seen anything like this happen before with NSNotifications?</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks!</p>
