Adding header to a scope title in TableViewController (Swift - Xcode) - swift

Question

It's quite hard to explain but how can i add a header only to a scope button title instead of to the whole tableviewcontroller? For example, in the screenshots below, i only want the header "Most Interesting Booth" to appear when i tap on "Fun" A.K.A case 2 and not on "All" & "Top 10". Do comment if you are still unsure of what I'm saying. Thank you!
func searchBar(_ searchBar: UISearchBar, selectedScopeButtonIndexDidChange selectedScope: Int) {
switch selectedScope {
case 0:
postData.removeAll()
postData2.removeAll()
for data in tableDataArray {
postData.append(data.boothName)
let value = String(describing: data.boothRating)
postData2.append(value)
}
self.tableView.reloadData()
case 1:
postData.removeAll()
postData2.removeAll()
let sortedTableData = tableDataArray.sorted(by: { $0.boothRating > $1.boothRating })
for data in sortedTableData {
postData.append(data.boothName)
let value = String(describing: data.boothRating)
postData2.append(value)
}
self.tableView.reloadData()
case 2:
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> UIView? {
let view = UIView()
view.backgroundColor = UIColor.orange
return view
}
postData.removeAll()
postData2.removeAll()
let sortedTableData = tableDataArray.sorted(by: { $0.boothRating > $1.boothRating })
for data in sortedTableData {
postData.append(data.boothName)
let value = String(describing: data.boothRating)
postData2.append(value)
}
self.tableView.reloadData()
default:
break
}
tableView.reloadData()
}

I suggest to do it in this way, you can use an enum to have a cleaner reference when you update your table view.
Create an enum, for example:
enum BoothScope: Int {
case all
case top
case fun
}
Add a BoothScope var:
var selectedBoothScope: BoothScope = .all
And you can manage it in this way:
func searchBar(_ searchBar: UISearchBar, selectedScopeButtonIndexDidChange selectedScope: Int) {
guard selectedBoothScope == BoothScope(rawValue: selectedScope) else { return }
switch selectedBoothScope {
case .all:
//...
case .top:
//...
case .fun:
//remove this:
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> UIView? {
let view = UIView()
view.backgroundColor = UIColor.orange
return view
}
//...
And finally:
(if you prefer you can use the delegate func tableView(_ tableView: UITableView,
viewForHeaderInSection section: Int) -> UIView?)
func tableView(_ tableView: UITableView,titleForHeaderInSection section: Int) -> String? {
return "yourTitle"
}
func tableView(_ tableView: UITableView,heightForHeaderInSection section: Int) -> CGFloat {
if selectedBoothScope == .fun {
return 30
}
return 0
}
