使用：
PublicTableView *publicTableView = [[PublicTableView alloc] initWithFrame:self.view.frame
                                                                        style:UITableViewStylePlain
                                                            cellWithClassName:@"MyCell"
                                                               cellWithMethod:@"cellConfig:"
                                                            cellWithIsUserNib:YES];
   
    [self.view addSubview:publicTableView];
   
    publicTableView.dataList = dataList;
   
    [publicTableView blockWithCellSelectRowAtIndexPath:^(UITableView *tableView, NSIndexPath *indexPath) {
       
    }];


注意：这里只需要把每个cell的类名，及配置数据的方法传进去就可以了
