如何在 iOS Objective-C 的 UITableView 中创建类别和子类别选择
我想在 UITableView 中使用 iOS 的 Objective-C 创建一个带有类别和子类别选择的表格视图，但我不知道要搜索什么以及从哪里开始.类别和子类别的内容是动态的，可以是一个或多个，然后由Web服务结果决定.并且所有类别都应立即折叠.它应该是这样的.

我认为你应该创建一个带有 'parentCategory' 属性的 CategoryViewController.
I think you should create a CategoryViewController with a 'parentCategory' property.
最初此属性为空，它将加载您的所有基本类别.然后，当您选择一个类别(如果它有子类别)时，您将对相同的 CategoryViewController 执行 segue 并设置此 parentCategory 属性.您将使用此属性加载子类别.
Initially this property will be empty and it will load all of your base categories. Then when you select a category if it has children you will perform a segue to the same CategoryViewController and set this parentCategory property. You will use this property to load up the child categories.
