iOS写好好友列表之后，不知道该怎么在cell的点击事件里面跳转到与该好友单聊的界面，需要传值的知道，但是具体怎么写不知道啊

如题

//cell跳转
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    
    if (_delegate && [_delegate respondsToSelector:@selector(userListViewController:didSelectUserModel:)]) {
//        id model = nil;
        EaseUserModel *model = nil;

        if ([_dataSource respondsToSelector:@selector(userListViewController:userModelForIndexPath:)]) {
            model = [_dataSource userListViewController:self userModelForIndexPath:indexPath];

        }
        else {
            model = [self.buddyArray objectAtIndex:indexPath.row];

        }
        
        if (model) {
            [_delegate userListViewController:self didSelectUserModel:model];
        }
 
        
    }
}
就是这里面我应该怎么写呢
