如何写静态tableView页面

学习了这篇文章 架构篇-谈谈如何写个人中心这类页面(静态tableView页面的编写)
给自己的学习做个记录。
根据自己的理解重写了一部分代码。

使用例子

1. e.g.

   - (void)viewDidLoad {
    [super viewDidLoad];
 WynStaticTableView *tableView = [[WynStaticTableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];

    tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
    tableView.backgroundColor = [UIColor lightTextColor];

    tableView.headerHeight = 20.f;

    ......

    BaseCellDescriber *cell0 = [BaseCellDescriber new];
    cell0.identifier = kBaseCell;
    cell0.textLabel_text = @"UITableViewCell";
    cell0.textLabel_textColor = [UIColor brownColor];
    cell0.detailTextLabel_text = @"detailTextLabel_text";
    cell0.detailTextLabel_textColor = [UIColor brownColor];
    cell0.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    cell0.selectCellBlock = ^(WynBaseStaticCell *cell, BaseCellDescriber *describer) {
        NSLog(@"*=*=%s=*=*", __func__);
    };

    [tableView loadCellDescribers:@[@[cell2Data, cell0], @[cell3Data]]];
        [tableView registNibCells:nil classCells:@[ kUITableViewCell]];

    [self.view addSubview:tableView];
    [tableView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.edges.equalTo(self.view);
    }];

}

1. e.g.

    [tableView addCellDescriber:^BaseCellDescriber *{
        MCDemoTableDescribeData *cell3Data = [[MCDemoTableDescribeData alloc] init];
        cell3Data.identifier = @"MCDemoCell3";
        cell3Data.indicateImageName = @"indicate";
        cell3Data.title = @"cell3";
        cell3Data.subTitle = @"cell3's subtitle";

        return cell3Data;
    } inSection:0];

    [tableView addCellDescriber:^BaseCellDescriber *{
        BaseCellDescriber *cell0 = [BaseCellDescriber new];
        cell0.identifier = kBaseCell;
        cell0.textLabel_text = @"UITableViewCell";
        cell0.textLabel_textColor = [UIColor brownColor];
        cell0.detailTextLabel_text = @"detailTextLabel_text";
        cell0.detailTextLabel_textColor = [UIColor brownColor];
        cell0.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        cell0.selectCellBlock = ^(WynBaseStaticCell *cell, BaseCellDescriber *describer) {
            NSLog(@"*=*=%s=*=*", __func__);
        };
        return cell0;
    } inSection:1];

推荐用第二种吧。
