UIAlertView + TextField = NSString
<p>If I had a correctly placed UITextField on an UIAlertView, could I assign the TextField's text value inside NSString using:</p>

<pre><code>NSString *string = myTextField.text
</code></pre>

<p>And what is the method for doing that when the UIAlertView's Button is pressed? (all of my code is on the<code>-(void)applicationDidFinishLaunching</code>method.)</p>
