title: CGSize to pixels / points confusion
body: <p>I have got this code:</p>
  
  <pre><code>CGRect _frame = container.frame;
  CGFloat height = _frame.size.height
  </code></pre>
  
  <p>This code gives me the height of the view but in what units? Is there a way to convert it to pixels or points so I could visualize it a bit better?</p>
  
  <p>I have read in the documentation that CGSize is a vector rather than a physical value but that doesn't me help much in understanding it.</p>
  
  <p>Thank you!</p>
