title: iOS - is it possible to download bundles from the internet with updated xibs?
body: <p>I want to be able to customize xibs in my app after the app is released by changing xibs, bundling them, downloading that bundle and having the client configured to look in those new bundles for the new xibs. </p>
  
  <p>So far, I have added a xib to a bundle I created and am attempting to download it:</p>
  
  <pre><code>   // bundle URL is NSURL to uploaded resource for bundle
     NSBundle *myBundle = [[NSBundle bundleWithURL:bundleURL] retain];
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSBundle initWithURL:]: non-file URL argument'
  </code></pre>
  
  <p>My question: is it possible to do what I set out to do? This error suggests it is not possible.</p>
  
  <p>If it isn't possible to download bundles, would it be possible to download just a xib and use that?</p>
  
  <p>Thanks!</p>
