What are my options for viewing hierarchies in iOS? In OSX I have the option of using NSOutlineView. Ideally I should be able to support at least 3 levels.

推荐答案

不多.表格视图支持部分和行，为您提供2级.

Not much. Table views support sections and rows, which gives you 2 levels.

您可以使用UICollectionView并滚动自己的数据层次结构，但我认为iOS中没有等效于NSOutlineView的东西. UI元素是专为手机上的小屏幕而设计的，在该屏幕上，您实际上没有足够的空间来呈现多个级别的数据.苹果增加了一些额外的控件，例如iPad的拆分视图控制器，但实际上不是轮廓查看器.

You could use a UICollectionView and roll your own hierarchy of data, but I don't think there is an equivalent to NSOutlineView in iOS. The UI Elements are designed for the small screen on a phone, where you don't really have enough space to present multiple levels of data. Apple added a few extra controls like a split view controller for iPad, but not really an outline viewer.

iOS上的标准是使用多个级别的主视图/详细视图.您从顶层逐项向下钻取，直到找到所需的详细信息.

The norm on iOS is to use multiple levels of master/detail views. You drill down from the top level item by item until you get to the detail you're looking for.
