Not recieving UITextField messages
<p>I need to do some processing after my user leaves a text field. </p>

<p>I thought I had turned on notification by doing this:</p>

<pre><code>@interface CreditCardAppViewController : UIViewController 
    &lt;UITextFieldDelegate&gt; {
</code></pre>

<p>However, my events are not getting fired. I don't know why?</p>

<pre><code>- (void)textFieldDidBeginEditing:(UITextField *)textField {

NSLog(@"This never gets called, Why?");
</code></pre>

<p>}</p>
