title: Loading image with AFNetworking - Resizing
body: <p>First of all, I'm using this <code>AFNetworking</code> method:</p>
  
  <pre><code>[imageView setImageWithURL:[NSURL URLWithString:@"http://site.com/img.png"]];
  </code></pre>
  
  <p><strong>1 -</strong> This method is asynchronous? It will cache the image in iPhone?</p>
  
  <p><strong>2 -</strong> How can I crop/resize this image? I have a 800x600 image in the URL, but my UIImageView is 400x400, I only want to have the url image cropped before being shown, to be the same ratio, like 600x600 (It's not needed to be 400x400, just same ratio). Like facebook app.</p>
