If you use UITableView and iOS 8, you can use autolayout to determine the cell height and setup constraints inside cell to hide/show the options. see how to implement dynamic cell height – http://www.raywenderlich.com/87975/dynamic-table-view-cell-height-ios-8-swift ).

I use FXForms to handle such options tables but you need to look little bit deeper into this to be able to subclass the cells properly. Check that out here: https://github.com/nicklockwood/FXForms

I think you should create a CategoryViewController with a 'parentCategory' property.

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.
