<pre><code>   View      
     |_my UIIMageView 1 
     |

<p>I can handle the touch down event by following the solution at this <a href="http://stackoverflow.com/questions/8976478/detect-a-touch-down-event-on-uiimageviews">post</a></p>

<p>However, if my Story Board is changed to</p>

<pre><code>   Scroll View      
     |_my UIIMageView 1 
     |
     |_my UIImageView 2
</code></pre>

Please help me on this issue..</p>
