...Now, it's for you to decide, should or not your menu drop from top left corner of the screen or from your navigation bar, because if you want animation like in the example, you must make your menu view controller conform to "GuillotineMenu" protocol. When you confirm to this protocol, you must make a menu button and title, you don't need to make a frame for them, because the animator will make it itself. In view controller, which will present your menu, you must make a property for "GuillotineMenuTransitionAnimator". It's necessary for proper animation when you show or dismiss the menu.
