IOS: prepareForSegue callback for another direction (i.e. the return button is pressed)

Question

I am wondering if there is a callback similar to prepareForSegue that is called when the parent UIViewController is returned when the user offers the [back] button.

I would also like to receive the information from which the user controller was received, from which the user clicked the "Back" button.

Use delegate methods if you want to get data back from a pressed (or modal) VC. If you need an example, check here.
