You should manually add that button. If you look through sources of that SlideoutNavigationController
you will see that it adds the menu button only for that view controllers that you navigating through side menu. So you should manually set View.NavigationItem.RightBarButtonItem
or View.NavigationItem.RightBarButtonItem
and add on touch event call the ShowMenuRight/ShowMenuLeft
for other view controllers
private void SomeEvent(object sender, EventArgs e)
{
((AppDelegate)UIApplication.SharedApplication.Delegate).Menu.ShowMenuRight();
//or
//((AppDelegate)UIApplication.SharedApplication.Delegate).Menu.ShowMenuLeft();
}
