iPhone duplicate/copy a viewcontroller entirely

I have a view controller with user content like text/images/location data and i would like to duplicate the viewController and present it modally (presentModalViewController) when the user taps the edit button. The reason for doing this is because i want it to be clear that the user is entering the edit mode by using the transition/animation that comes w开发者_Go百科ith a modally presented controller.

Does anybody knows how to duplicate an entire viewController + its view? i don't want the overhead of reallocating the entire viewController. I tried a couple of things, but i haven't had any luck.

Any help/information would be welcome.

That sounds a little impractical. You could make an image of the current screen contents, present that using whatever animation you like on top of everything, and then remove it?

Or make other changes to your view (rearrangement of views, appearance of other controls, changes of colour) in your viewController's setEditing:animated: method.
