clear a view and redraw a image
<p>How to dealloc a view and realloc it?</p>

<p>Code:</p>

<pre><code>-(IBAction)CancelButton{

    [drawImage removeFromSuperview];
    [drawImage dealloc];
</code></pre>

<p>When you click on the cancel button the view gets cleared but nothing can be drawn on the page. I need to draw on the page.</p>
