iPhone - How to determine in which cell a button was pressed in a custom UITableViewCell

Question

I currently have a UITableView that is populated with a custom UITableViewCell that is in a separate nib. In the cell, there are two buttons that are wired to actions in th

Much easier solution is to define your button callback with (id)sender and use that to dig out the table row index. Here's some sample code:

- (IBAction)buttonWasPressed:(id)sender
{
    NSIndexPath *indexPath =
        [self.myTableView
         indexPathForCell:(UITableViewCell *)[[sender superview] superview]];
    NSUInteger row = indexPath.row;

    // Do something with row index
}

Most likely you used that same row index to create/fill the cell, so it should be trivial to identify what your button should now do. No need to play with tags and try to keep them in order!

Clarification: if you currently use -(IBAction)buttonWasPressed; just redefine it as -(IBAction)buttonWasPressed:(id)sender; The additional callback argument is there, no need to do anything extra to get it. Also remember to reconnect your button to new callback in Interface Builder!
