The UIAlertController has an array of textFields that are ordered by when you added them (the first one you added is index 0). Since it is a generic array, you will have to cast the result before accessing the text field.

__weak UIAlertController *alertRef = alertController;
UIAlertAction* okAction = [UIAlertAction actionWithTitle:@"Button Text"
                                         handler:^(UIAlertAction * action) {
                                             // access text from text field
                                             NSString *text = ((UITextField *)[alertRef.textFields objectAtIndex:0]).text;
                                         }];
