我有一个应用程序，其中在我的HomeVc中，我使用两个表视图，一个用于显示collectionview单元的数据，另一个用于显示来自同一API的搜索结果。现在的问题是，如果未选择api中的搜索参数，则应显示整个数据，包括类别和子类别；如果选择了搜索参数，则应选择特定的数据，包括类别和子类别。例如：“食品”是主要类别，“水果”，“蔬菜”等是子类别。现在，当我键入食物时，应显示与食物相关的所有数据，即水果，蔬菜等，如果我键入水果，则应仅显示水果。我已经尝试过但没有得到。我希望当我搜索食物时，食物，水果，蔬菜等应显示。当我仅搜索“水果”时，应该显示水果，而当什么都没有时，则应该显示所有数据。我尝试了所有可能的方法，但是没有运气。谁能帮助我。
在我的代码中。我已经实现了所有tableview数据源和委托方法，我认为在cellforrow方法中，出现了问题，而在API解析功能中，有问题了

我的homevc的屏幕快照，其中显示了作为tableview标头seciton列出的类别以及在collectionview单元格中列出的子类别，我也想在点击子类别时导航到每个词都包含在每个子类别下的屏幕： homevc image
选择类别和子类别时得到的结果屏幕截图
