title: Programmatically hiding Apple iAd ADBannerView
body: <p>I'd like to occasionally hide an <code>ADBannerView</code>. I'm thinking about <code>banner.hidden = YES</code> and similar to un-hide. I'm concerned that Apple will frown upon this because receiving and "displaying" ads while the banner is hidden seems questionable. </p>
  
  <p>In <code>bannerView:didFailToReceiveAdWithError:</code> I'm animating the banner off the screen bottom. I'm open to doing this instead of using the hidden property if it's somehow better.</p>
  
  <p>Perhaps it's possible to tell the banner to stop requesting ads. Unfortunately nothing jumped out at me while looking over <code>ADBannerView.h</code>.</p>
  
  <p><strong>What's the best way to programatically hide <code>ADBannerView</code>?</strong></p>
