ios - How to properly insert new row in correct specific row cell in the table view (swift)? -

so here question..

i trying insert row in index add button inside row..

example : click add button @ row 1, should add new row below row, if click add button @ row 3 should add new row below it..

the problem after add example 5 new row, if click add in row 5 (this new row added new add button inside it) keep adding below last row clicked.. (i click add on row 3 has new row below it, click add on new row keep adding below row 3)

steps in gif :

1. i add new first row adding new row below it.. (correct behavior)
2. i try add new row in last row keep adding new row below row 3. (wrong behavior)
3. i try click again add row in row 4 correctly add new row below it, , click on row 3 , add correctly new row below it. (correct behavior)

why keep problem in number 2 ?

here code :

the problem in case ingredient , step.. give rowid in cell using indexpath each cell has own id.

func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {         let item = items[indexpath.section]         switch item.type {         case .title:             if let cell = tableview.dequeuereusablecell(withidentifier: popuptitlecell.identifier, for: indexpath) as? popuptitlecell {                 return cell             }         case .category:             if let cell = tableview.dequeuereusablecell(withidentifier: popupcategorycell.identifier, for: indexpath) as? popupcategorycell {                 return cell             }         case .ingredient:             if let item = item as? popupmodelingredient, let cell = tableview.dequeuereusablecell(withidentifier: popupingredientstepcell.identifier, for: indexpath) as? popupingredientstepcell {                 cell.cellid = indexpath.row                 cell.item = item                 cell.delegate = self                 return cell             }         case .step:             if let item = item as? popupmodelstep, let cell = tableview.dequeuereusablecell(withidentifier: popupingredientstepcell.identifier, for: indexpath) as? popupingredientstepcell {                 cell.cellid = indexpath.row                 cell.item = item                 cell.delegate = self                 return cell             }         case .post:             if let cell = tableview.dequeuereusablecell(withidentifier: popuppostcell.identifier, for: indexpath) as? popuppostcell {                 return cell             }         }         return uitableviewcell()     } 

this 1 delegate handler create pass cell click add button

func addednewcell(insection: int, cellid: int) {         popuptableview?.beginupdates()         let item = items[insection]         if let item = item as? popupmodelingredient {             item.ingredientscell += 1             popuptableview?.insertrows(at: [indexpath(row: cellid, section: insection)], with: .automatic)         }else if let item = item as? popupmodelstep {             item.stepscell += 1             popuptableview?.insertrows(at: [indexpath(row: cellid, section: insection)], with: .automatic)         }         popuptableview?.endupdates()         print("added in section \(insection) , cell id \(cellid)")     } 

the last 1 cell itself

class popupingredientstepcell: uitableviewcell {      var cellid: int?      var delegate: celladdeddelegate?      var item: popupviewmodelitem?      static var nib:uinib {         return uinib(nibname: identifier, bundle: nil)     }      static var identifier: string {         return string(describing: self)     }      @ibaction func addmorecell(_ sender: any) {         print("cell id 1 : ", cellid)         if item?.type == .ingredient {             delegate?.addednewcell(insection: 2, cellid: cellid! + 1)         }else{             delegate?.addednewcell(insection: 3, cellid: cellid! + 1)         }      }   }
