How to use as a UIBarButtonItem

How can I use ExpandingMenu as a UIBarButtonItem? When I set it as a right UIBarButtonItem through custom view, when expanded it rises up off of the screen and doesn't allow me to touch around. I then tried to add it to the view's window, and when opened up constrained by auto layout, opening it up the options were completely off of the screen far to the right. How can I use the Expanding Menu as a "bar button" or at least make it seem as if it is a right bar button giving the user options?
