UITableView cells with buttons

I want to have a UIButton in each UITableViewCell that will allow me to perform selector on the object corresponding to that row. They way I got it working was to create a separate UITableViewCell for each row (no reuse), add a new UIButton that is tagged with the row. When the button gets tapped, the resulting selector checks the tag of the sender to determine which object to change.

Is there a better way of doing this? For one, I am not reusing cells which is unfortunate, and using UIView.tag seems very hacky.

You can use the same tag number on all of the UIButtons.

To extract the row number which has been clicked, implement this code in the selector: 

- (void)buttonClicked:(id)sender

{

    UITableViewCell * clickedCell = (UITableViewCell *)[[sender superview] superview];

    NSIndexPath * clickedButtonPath = [self.tableView indexPathForCell:clickedCell];

    int rownumber = clickedButtonPath.row;
}

I would make a subclass of UITableViewCell so that it stores a reference to a button. Then set that button when you dequeue a cell. In the method that is called, sender will be the button and you can ask for it's superview and then ask that (which is the cell) for it's index.
