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。
