Question

我正在创建一个应用程序，其中有一个控制器，其中有一个表格视图，当选择c分类区域中的单元格或存储区域中的单元格或仅选择一个时，将显示上一屏的数据，然后单击应用中显示双箭头按钮，则它应导航到表格视图屏幕，并应将类别或存储中的所有数据或两者都显示到表格视图中。在tableview控制器中，我有一个API，该API为POST，其主体参数为'term_ids'，其中包含值556,574，以逗号分隔，表示前一个用于类别，后一个用于存储，或者两个ID都包含类别数据或存储数据。意味着我必须传递两个id并将它们用逗号分隔，然后传递给tableview控制器

在类别屏幕快照中说，我已经选择了前两个单元格，当我点击双箭头按钮时，所选单元格数据应传递到另一个屏幕截图，其屏幕截图如下：

类别数据的

api链接：https://api.myjson.com/bins/wggld 用于存储数据的api链接：https://api.myjson.com/bins/1fc46p 优惠券的api链接，我需要根据类别中的ID填充到tableview中并存储api链接：https://api.myjson.com/bins/1c4dip

我的应用屏幕截图，用于更好地理解：

我要在其中填充数据的类别屏幕和主主屏幕的

代码如下：

categoryViewController的代码如下：
