iPhone SDK: How can you hide an alert box?
<p>I am using the following code to show an alert box:</p>

<pre><code>UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Info" message:@"My Message" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];  
[alert show];  
[alert release];
</code></pre>

<p>Can you tell me how to hide the alert box again when the phone changes orientation?</p>
