Как получить индекс нажатой accessory button?

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{}

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {}

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"details" sender:indexPath];

}

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"workout"]) {
        
        UITableViewCell *cell = (UITableViewCell*)sender;
        NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
        
        WorkoutTVC *wvc = (WorkoutTVC *) segue.destinationViewController;
        wvc.workoutName = [self.listOfWorkoutNames objectAtIndex:indexPath.row];
    }
    else if ([segue.identifier isEqualToString:@"details"]) {
        
        NSIndexPath *indexPath = [sender isKindOfClass:[NSIndexPath class]] ? (NSIndexPath*)sender : [self.tableView indexPathForSelectedRow];
        
        WorkoutDetailsVC *wdvc = (WorkoutDetailsVC *) segue.destinationViewController;
        wdvc.workoutName = [self.listOfWorkoutNames objectAtIndex:indexPath.row];
    }
}
