Pushing a UIViewController should not produce a double Navigation Bar effect unless one is added after loading the view, and not as part of the application's UINavigationController. Nevertheless, you can Push a UIViewController using,

[[self navigationController] pushViewController:yourViewController animated:YES/NO];

If your UIViewController is designed using Storyboard, then you can call it by using the following code. (Remember to set the Storyboard Identifier of your DDMenuController to something, as it will be using in the following code.)

//Add this to the top of your page with the other imports.
#import "DDMenuController.h"

//Add this to the selector called by your UIButton.
DDMenuController *ddMenu = (DDMenuController *)[[self storyboard] instantiateViewControllerWithIdentifier:@"DDMenuVC"];
[[self navigationController] pushViewController:ddMenu animated:YES/NO];
