ios - 使用动态字典创建可扩展 TableView

Question

我想在 iOS 中创建一个带有子菜单内容的菜单结构。我从以下位置得到以下字典:

{
    "post_Type": "subject",
    "head": "Edho",
    "abbreviation": "histophya”,
    "title": "Edho",
    "body": "Edho",
    "Tree": [{
        "post_Type": "topic",
        "head": "Edho/teaologie",
        "title": "<span>teaologie</span>",
        "body": "teaologie"
    }, {
        "post_Type": "topic",
        "head": "Edho/abcedf",
        "title": "<span>abcedf</span>",
        "body": "abcedf"
    }, {
        "post_Type": "topic",
        "head": "Edho/his+food+system+and+blut",
        "title": "<span>his-food-system-and-Blut</span>",
        "body": "his food system+and+blut"
    }, {
        "post_Type": "topic",
        "head": "Edho/Lump+abcedf+and+immunsystem",
        "title": "<span>Lump abcedf and Immunsystem</span>",
        "body": "Lump+abcedf+and+immunsystem"
    }, {
        "post_Type": "topic",
        "head": "Edho/rationsystem",
        "title": "<span>rationsystem</span>",
        "body": "rationsystem"

Answer 1

使用 RATreeView，它是树结构的最佳 pod:http://cocoadocs.org/docsets/RATreeView/0.2.2/

RATreeView 是一个旨在支持在 IOS 上实现 TreeView 的类。它用作 UITableView 的包装器，定义自己的委托(delegate)和数据源方法，以便更轻松地管理树数据结构。

由于 RATreeView 是 UITableView 的包装器，因此大多数委托(delegate)和数据源方法只是 UITableView 委托(delegate)和数据源协议(protocol)的特定方法的等价物。它们在为树结构提供更容易管理的方式上发生了变化。协议(protocol)中也有一些新方法来支持展开和折叠 TreeView 的行。它应该适用于 IOS 5.0+。
