hi,
i managed to do this for my app. (think i referred to viewTransitions sample code and modified quite a bit)
i can't remember this well cos i did this quite a while back, but i will try to help as much as possible
1) from the appdelegate i initialize a root controller (view controller class)
2) this root controller actually contains two other view controllers, let's call it viewAController and viewBController, for the screens which u are going to toggle in between. and there's also a function, let's call it toggleMenu, which will set the menus to and fro. i copied this whole chunk from the sample code. it actually defines the code on what to do, i.e. if current view is A switch to B and vice versa.
3) inside the controller files, you need to implement the toggleMenu function too, which basically calls the rootController's toggleMenu
4) we also need viewA and viewB files(view class)
5) need to add the .xib files for the respective views and link them up to the controller class. i did not use the .xib files for ui layout though, because of my app's needs. however, it will not work properly without the .xib files.
5) inside the view class of both views, i.e. viewA.m and viewB.m, you need to create a button, that will call the toggleMenu function inside the respective controller class.
it will look something like this:
[Button addTarget:ViewAController action:@selector(toggleMenu:) forControlEvents:UIControlEventTouchUpInside];
so the flow is really button (in view)-> toggleMenu(viewController) -> toggleMenu(rootController)
i'm sorry it sounds pretty hazy, i did this part weeks before and can't really remember. i hope it helps.
