Can't find the actual 'detail button' in a tableView's row

Question

When I click on my tableView's detail-button... I can manage to get the section number, the row number, and even the cell itself... but why is the actual "detail button" unobtainable? (NSLog always displays "(null)" for the button.)

- (void) tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    int section = indexPath.section;
    int row     = indexPath.row;

    UITableViewCell *aCell = [tableView cellForRowAtIndexPath:indexPath];
    UIButton *detailButton = (UIButton *)[aCell accessoryView];

    // Why is detailButton null?
    NSLog(@"accessory button tapped for row with index path %d x %d \n cell=(%@) \n button=(%@)", section, row, aCell, detailButton);
}

Answer 1

The accessory view is a UIView not a UIButton. Perhaps casting it to a button throws off the description method. Just a guess.
