Question

I got a hard job to be done. I try to attach additional information to a UITableViewCell.
The tableViewCells got buttons inside that I subclassed to do that (I’m passing a NSString).

Now, when the user clicks on a tableRow, I want to fire an other method and want to pass the same string.
I created a subclass of UITableViewCell and added the string to it.

But I can’t get the value of the string in tableView:didSelectRowAtIndexPath:.
That’s because UITableView returns an UITableViewCell and not my custom subclass:

[tableView cellForRowAtIndexPath:indexPath].passString
    → /* Property 'passString not found on object of type UITableViewCell */

When I do NSLog(@"%@", [tableView cellForRowAtIndexPath:indexPath]); I can see the property on the log.

Now my question:
How can I get this subclass property in other methods?!

I don’t want to subclass UITableView as well. I’d end up subclassing like every UIElement I’m using :'(

Thanks for help, greetings

Jullian just type cast UITableViewCell to your custom class like

CustomCell *cell = (CustomCell*)[tableView cellForRowAtIndexPath:indexPath];
cell. passString; //it will work

or you can pass message instead of dot operator
[[tableView cellForRowAtIndexPath:indexPath] passString];

it will give you warning but will work if it is the object of you CustomCell. Prefer using first method as I don’t like warnings in my code.
