Cannot specify a "storyboard id" of UIViewController in makeAnAlert method

[ratulSharker]

While instantiating a AlertView using the class method

/*   _______________________________________________________
     |                                                                                       |
     |  a static class method, which is meant to act as a   |
     |  factory method for the RSViewcontrollerAlertView.|
     |______________________________________________________|
*/
+(RSViewControllerAlertView*)makeAnAlert:(NSString*)storyboardName;

we can specify only the storyboard name, and the RSViewControllerAlertView assumes that the initial view controller is the view controller which needed to be rendered.

How could i specify a view controller which is not initial view controller in the given storyboard file ?
