ios - How can I subclass a UITableView?

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?

If I understood you, you need this class declaration:

@interface ShareUITableView : UITableView <UITableViewDataSource>

And then, in your class constructor, you should assign the instance itself as its own datasource:

- (id)init
{
    //...
    self.dataSource = self;
    //...
}

Of course, the class will have to adopt the protocol.

Good luck!
