title: Find Frame Coordinates After UIView Transform is Applied (CGAffineTransform)
body: <p>I rotate my view with <code>CGAffineTransform</code></p>
  <pre><code>[view setTransform:newTransform];
  </code></pre>
  <p>The frame values remain the same after transform is applied but how do I find &quot;rotated&quot; or transformed values of this frame?</p>

  <p>I want the exact coordinates of rotated frame edges, that is a, b, c, d points.</p>
