how to add undo manager for multiple UIView

I need some idea to how perform undo opertaion with UndoManager.

In my app user can add as many gifts (UIView) on a screen. He can rearrange & resize all added gifts on that screen.

For adding, rearranging & resizing gifts, I have made a subclass of UIView & in that class I have implemented code for the same operations on touch delegates.

Now my question is that if user has rearranged multiple gifts & also resize some of them, how I can implement a undomanager to restore all the gifts in original position.

Any idea or suggestion would be great at this time.

If you want to undo the change of position, size & rotation of UIViews, you need to hold the frame, transform of it when the gesture started. So that when perform undo, you can revert to the initial values.
