When clicked on each person , the subordinates list of that person should appear at the bottom. The whole list is dynamic .

This is the json to be used .I have tried with collection view inside table view.But failed when i try to delete a row when user moves to the top and clicks on a new person . I have seen many libraries showing tree structure for table view . But i think that cannot be used here .
This is what i have tried so far.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return selectedIndexes.count + 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var bottomCell : SubordinatesTableViewCell! = self.Extableview.dequeueReusableCell(withIdentifier: "SubordinatesTableViewCell") as? SubordinatesTableViewCell
if bottomCell == nil {
let nib:Array = Bundle.main.loadNibNamed("SubordinatesTableViewCell", owner: self, options: nil)!
bottomCell = nib[0] as? SubordinatesTableViewCell
}
bottomCell.empLevel = indexPath.row
bottomCell.delegate = self
bottomCell.subordinateDetails = self.subordinatesList
return bottomCell
}
extension CurrentVC : SubordinateCellDelegate {
func employeeClicked(row: Int?, index: Int?) {
self.subordinatesList = self.heirarchy?.subordinates
self.currentHeirarchyLevel = row! + 1
if self.Extableview.numberOfRows(inSection: 0) > row! + 1 {
var newIndexes = [Int]()
if row! == 0 {
self.selectedIndexes.removeAll()
self.selectedIndexes.append(index!)
}else {
for i in 0..<(row! + 1) {
newIndexes.append(selectedIndexes[i])
}
self.selectedIndexes = newIndexes
self.selectedIndexes.append(index!)
}
for i in 0..<row! + 1 {
self.subordinatesList = self.subordinatesList?[self.selectedIndexes[i]].subordinates
print(subordinatesList)
}
if subordinatesList?.count ?? 0 > 0 {
self.Extableview.reloadRows(at: [IndexPath(row: self.currentHeirarchyLevel, section: 0)], with: .fade)
}else {
for i in 0..<self.Extableview.numberOfRows(inSection: 0) {
if i > row! {
self.Extableview.beginUpdates()
self.Extableview.deleteRows(at: [IndexPath(row: 1, section: 0)], with: .fade)
}
}
self.numOfsections = row! + 1
self.Extableview.endUpdates()
}
}else {
self.selectedIndexes.append(index!)
for i in 0..<row! + 1 {
self.subordinatesList = self.subordinatesList?[self.selectedIndexes[i]].subordinates
}
if self.subordinatesList?.count ?? 0 > 0 {
self.Extableview.beginUpdates()
self.numOfsections = row! + 2
self.Extableview.insertRows(at: [IndexPath(row: row! + 1, section: 0)], with: .none)
self.Extableview.endUpdates()
}else {
for i in 0..<self.Extableview.numberOfRows(inSection: 0) {
if i > row! {
self.Extableview.beginUpdates()
self.numOfsections = row! + 1
self.Extableview.deleteRows(at: [IndexPath(row: 1, section: 0)], with: .fade)
}
}
self.Extableview.endUpdates()
}
}
}
}

Declare 4 variables ,
var heirarchy : Subordinates?
var numOfRows = 0
var subordinatesList : [Subordinates]?
var subList = [[Subordinates]?]()
Once you get the json response ,
self.numOfRows += 1
self.subordinatesList?.append(self.heirarchy!)
self.subList.append([self.heirarchy!])
Create a delegate function for collection view item click as below .
func employeeClicked(row: Int?, index: Int?, subordinates: [Subordinates]?) {
if (subordinates?.count ?? 0) > 0 {
self.subordinatesList = subordinates
if numOfRows > row! + 2 {
self.tableView.beginUpdates()
for i in (row! + 1)..<tableView.numberOfRows(inSection: 0) {
self.tableView.deleteRows(at: [IndexPath(row: i, section: 0)], with: .fade)
self.numOfRows = numOfRows - 1
self.subList.removeLast()
}
self.subList.append(self.subordinatesList)
self.numOfRows = row! + 2
self.tableView.insertRows(at: [IndexPath(row: row! + 1, section: 0)], with: .fade)
self.tableView.endUpdates()
}
else if numOfRows == row! + 2 {
self.subList[row! + 1] = self.subordinatesList
self.tableView.reloadRows(at: [IndexPath(row: row! + 1, section: 0)], with: .fade)
}else {
self.subList.append(self.subordinatesList)
self.numOfRows = row! + 2
self.tableView.insertRows(at: [IndexPath(row: row! + 1, section: 0)], with: .fade)
}
}else {
if numOfRows > row! + 1 {
self.tableView.beginUpdates()
for i in (row! + 1)..<tableView.numberOfRows(inSection: 0) {
self.tableView.deleteRows(at: [IndexPath(row: i, section: 0)], with: .fade)
self.numOfRows = numOfRows - 1
self.subList.removeLast()
}
self.tableView.endUpdates()
}
}
self.tableView.scrollToBottom()
}
}
In tableview cellfor row delegate use the value of sublist array. Hope this helps you . I checked the code and it is working fine for me.
