Passing data between to the parent view controller from a modal

So I've got a "reminders" app. I have a table view controller as my main view controller and an "add reminder" view controller which is modal. I want to pass the new reminder data to the mutable array of the the table view controller. I guess i need something like prepareForSegue but it's not really a segue... So how do i do that? Thanks

If you have to viewControllers, A and B. B is presented modally and you want to pass information back to A. You could use blocks, notifications or delegates. In your case delegates would be the best choice.

Here is a tiny example to demonstrate:
