objective c - Buttons for each row UITableView

Question

I have a custom cell in a UITableView, defined by a custom class (.h and .m files). I am able to display the cell, and change the text for each cell in the list, but my custom cell also has buttons in it (two, actually). When I click the button, I need to know which row's button has been clicked. Is there any way to get this within the custom ui cell class?

I hope what I'm requesting is clear. If not, feel free to comment and I'll try to explain as best as possible.

You don't show any code to comment on, but generally speaking you can:

1. define a tag for each button which represents the table row where the button appears;

2. when your button action method is called, you can access then the tag property of the button to know which row it was.

      - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
      {
          UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
          if (cell == nil) {
            ...
          }
          ...
          [button setTag:indexPath.row];
          ...
      }
   
   
      - (void)buttonPressedAction:(id)sender
      {
          UIButton *button = (UIButton *)sender;
          int row = button.tag;
      }
