Question

I followed this discussion: UITableView issue when using separate delegate/dataSource, and even though I found it super informative and useful, I have a follow up question:

So I’ve got a similar setup where I have a UITableView within the UIView. The UIView is controlled by it’s own UIViewController (let’s call it MyUIViewController) and also I moved the delegate and datasource for the UITableView into a separate subclass of UITableViewController (say, MyUITableViewController).

Everything works fine with the tableView.

The question is, how do I make a callback from MyUITableViewController to the MyUIViewController? For example, if the user selects a cell under the tableView which triggers didSelectRowAtIndexPath, I need to update something on the UIView which is actually a parent of this UITableView. So I basically need to send a message to MyUITableViewController. How would I do that?

You can use a delegate pattern in this case. I have a similar answer with sample code in this SO . In your case, the parent view controller is MyUIViewController. And the child view controller is MyUITableViewController.
