Question

I want to subclass a UITableView as I want to create a reusable table view component in my application.

The idea is instead of using a delegate for say cellForRowAtIndexPath I want the table view itself to get that call.

I don’t think I want a UITableViewController as this UITableView that I want to build has to live in various UIViewControllers (and these UIViewController might have UITableViews of their own).

I subclassed my UITableView as:

@interface ShareUITableView : UITableView

but none of its methods get called.

My ShareUITableView is created via the NIB by setting the custom class to ShareUITableView. I have verified in code that a ShareUITableView is instantiated.

My UITableView does not delegate to its view controller, so that’s not the problem.

Any ideas?

I think, you should still go with a Controller class. I expect subclassing UITableView to be tedious work — if possible with reasonable amount at all.

There is no problem to have UIViewController/NoViewController implemented the delegate and datasource and yet assign another controller to a specific tableView. note, that the datasource and delegate don’t need to be subclasses of UITableViewController.

have a look at this answer: Implement Delegate at Run Time?

My UITableView does not delegate to its view controller, so that’s not the problem.

You have to have to use delegate and datasource, that is how TableViews are filled and configured. otherwise you will have to overwrite every method of UITableView — including private ones, a no-go if you want into AppStore. Recreating UITableView without subclassing it would be even easier.
