title: How to make the UIAlertView call itself again?
body: <p>Below is the scenario.</p>
  
  <ol>
  <li><p>I have created a UIAlertView in viewDidLoad of the Controller in which I display the Alert.</p>
  
  <pre><code>loginAlert = [[UIAlertView alloc] initWithTitle:@"Check"
                                              message:@"Ok"
                                             delegate:nil
                                    cancelButtonTitle:@"Ok"
                                    otherButtonTitles:nil, nil];
  [loginAlert setAlertViewStyle:UIAlertViewStyleSecureTextInput]; 
  </code></pre></li>
  <li><p>I call it as [alert show] and it is displayed.</p></li>
  <li><p>When user press Ok, it goes to textEndEditing delegate method and from if nil/worng value was entered, I call [alert show] again.</p>
  
  <pre><code>- (void)textFieldDidEndEditing:(UITextField *)textField
  {
  if ([textField.text length] &gt; 0)
  {
  
  }
  else
  {
   NSLog(@"Checking");
   [loginAlert show];
  }
  }
  </code></pre></li>
  </ol>
  
  <p>But its not displayed again. Please tell me what to do? </p>
