title: Is there an equivalent of "renderInContext" for UIPrintPageRenderer
body: <p>You can call <code>renderInContext</code> on a layer. Is there something like that for <code>UIPrintPageRenderer</code>? I basically want to create a <code>UIImage</code> out of the first page of a PDF document of a <code>UIPrintPageRenderer</code>. I have the rest of the code except for the actual rendering in context part. </p>
  
  <p>Edit: Am I misunderstanding some basic underlying concept here? If so, please feel free to give me a quick lesson.</p>
