title: iPhone SDK: How can you hide an alert box?
body: <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>
