ios - how to access variables inside an enum? -

- 

class detailsviewcontroller: uiviewcontroller {     @iboutlet weak var summarybutton: uibarbuttonitem!     @iboutlet weak var commentarybutton: uibarbuttonitem!        enum viewstate: int {         case summary         case commentary          func setvisibility() {             switch (self) {                 case summary:                     summarybutton.enabled = true                     commentarybutton.enabled = false                 case commentary:                     summarybutton.enabled = false                     commentarybutton.enabled = true             }         }     } }

i not able access summarybutton , commentarybutton: gives error saying "detailsviewcontroller.type not have member named summarybutton"

how access summarybutton , commentarybutton?

solution: worked me

enum viewstate { case summary case commentary     }  class detailsviewcontroller: uiviewcontroller { @iboutlet weak var summarybutton: uibarbuttonitem! @iboutlet weak var commentarybutton: uibarbuttonitem!  var currentstate: viewstate = .summary {     didset {         switch (currentstate) {         case .summary:              summarybutton.enabled = true             commentarybutton.enabled = false             break         case .commentary:             summarybutton.enabled = false             commentarybutton.enabled = true             break         default:             break          }     } }

it seems me solution backwards. it's strange have enum own iboutlets buttons.

i move outlets , setvisibility method outside of enum , detailsviewcontroller. create instance variable currentviewstate of type viewstate in detailsviewcontroller, , make setvisibility method switch based on currentviewstate.
