passing imageview through delegate
<p>My programe does drag and move a little imageview by touch. When the location is decided, press a button to pass imageview to its superclass. </p>

<pre><code>-(void) sendPosition:(CGPoint)position ;
</code></pre>

<p>when I run program for first, it runs ok but after I rerun the same process right after that, it occurs error. </p>
