This would be a good time to use delegates. You would write a custom delegate protocol and have your tableview implement it. When you create your view with the datepicker, set a delegate property on it to point back to the UITableView subclass. Then call one of the delegate methods when the date needs to be stored.

This is a common design pattern for UITableViews, see Apple's documentation.
