RxSwift 这个框架看我就够了，这一篇我重点介绍
RxDataSources在实际开发中的运用，RxDataSources在tableview的分组是特别爽的。搞RxSwift，我是认真的

RxDataSources的分组效果是非常爽的，我们现在看一下它的封装
public typealias ConfigureCell = (TableViewSectionedDataSource, UITableView, IndexPath, I) -> UITableViewCell
public typealias TitleForHeaderInSection = (TableViewSectionedDataSource, Int) -> String?
public typealias TitleForFooterInSection = (TableViewSectionedDataSource, Int) -> String?
public typealias CanEditRowAtIndexPath = (TableViewSectionedDataSource, IndexPath) -> Bool
public typealias CanMoveRowAtIndexPath = (TableViewSectionedDataSource, IndexPath) -> Bool
定义了几个闭包，也是我们在分组中经常要用到的
public init(
configureCell: @escaping ConfigureCell,
titleForHeaderInSection: @escaping TitleForHeaderInSection = { _, _ in nil },
titleForFooterInSection: @escaping TitleForFooterInSection = { _, _ in nil },
canEditRowAtIndexPath: @escaping CanEditRowAtIndexPath = { _, _ in false },
canMoveRowAtIndexPath: @escaping CanMoveRowAtIndexPath = { _, _ in false },
sectionIndexTitles: @escaping SectionIndexTitles = { _ in nil },
sectionForSectionIndexTitle: @escaping SectionForSectionIndexTitle = { _, _, index in index }
) {
self.configureCell = configureCell
self.titleForHeaderInSection = titleForHeaderInSection
self.titleForFooterInSection = titleForFooterInSection
self.canEditRowAtIndexPath = canEditRowAtIndexPath
self.canMoveRowAtIndexPath = canMoveRowAtIndexPath
self.sectionIndexTitles = sectionIndexTitles
self.sectionForSectionIndexTitle = sectionForSectionIndexTitle
}
在初始化的时候就对上面的闭包进行了默认值处理（除了configureCell），这也很好解释，因为对于分组来说，其他那些头，尾都是非必须的，cell的逻辑才是必须要的，这也就促成了它封装两个
configureCell的方法的原因
