title: UIAlertView: UIAlertViewStyleSecureTextInput: Numeric keyboard
body: <p>I'm currently using this UIAlertView to do a login popup,</p>
  
  <pre><code>UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Restricted"
                                                  message:@"Please Enter Code to Enable Fields" 
                                                 delegate:self
                                        cancelButtonTitle:@"Cancel"
                                        otherButtonTitles:@"Login"
                        , nil];
  alert.alertViewStyle = UIAlertViewStyleSecureTextInput;
  
  [alert show];
  </code></pre>
  
  <p>However I would like the text input to be a numeric keyboard instead of the regular keyboard</p>
  
  <p>Is there a easy way to do this, or do I have to look into creating a custom UIAleartView</p>
