So the documentation you linked doesn't define a UINavigationController in it. So I assume I do something like:
SideDrawerGettingStarted main =
UINavigationCongtoller navigationController =
TKSideDrawerController sideDrawerController =
.Window.RootViewController = sideDrawerController;
This keeps the side drawer throughout the app, but now my custom UINavigationBar with the menu button gets overridden by the UINavigationControllers, even the example in the page you linked me, the UINavigationBar defined is overridden. So I am still a bit confused. Thanks for all the help so far!
