Question

我想在iOS中创建具有子菜单内容的菜单结构。我从以下字典中获取：

{
    "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",

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

RATreeView是一个旨在支持在IOS上实现树视图的类。它作为UITableView的包装器，定义自己的委托和数据源方法，以便更轻松地管理树数据结构。

由于RATreeView是UITableView的包装器，因此大多数委托和数据源方法只是UITableView委托和数据源协议的特定方法的等价物。它们改变了它们为树结构提供更容易管理的方式。协议中还有一些新方法可以支持扩展和折叠树视图的行。它应该适用于IOS 5.0 +。

使用动态字典
