title: Zoom and marker
body: <p>I have UIScrollView with UIImageView on it. On UIImageView I have round marker(one more UIImageView), which I can drag on UIImageView. I want to zoom my image on UIImageView, so:</p>
  
  <pre><code>- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
      return imageView;
  }
  </code></pre>
  
  <p>But when user is trying to zoom image my marker is zooming too. But I want to see my marker in its original size. How can I do it?</p>
