Issue when filtering with UISearchResults - ios

Question

So I have a list of friends coming from the API and I've tried to implement also the search functionality. So far, so good, the filtering is good, but my first section is actually a button that sends me to another VC and it 's getting irritating that that cell always appears when I try to search through the friend list. Actually, i want it to be hidden when I search for friends.
I added some pictures to make it more clear
As can be seen the third picture shows clearly the problem.
My code looks like.
var friendList = [Conversations]()
var filteredFriends = [Conversations]()
func numberOfSections(in tableView: UITableView) -> Int {
return friendList.count + 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if isFiltering() {
return filteredFriends.count
}
if section == 0 {
return 1
} else if section == 1 {
return friendList.count
}
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "NewGroupConversationCell") as! NewGroupConversationTableViewCell
return cell
} else if indexPath.section == 1 {
let cell = tableView.dequeueReusableCell(withIdentifier: "NewConversationCell") as! NewConversationTableViewCell
var friendList: Conversations
if isFiltering() {
friendList = filteredFriends[indexPath.row]
} else {
friendList = self.friendList[indexPath.row]
}
cell.populate(friendList)
return cell
}
return UITableViewCell()
}
func searchBarIsEmpty() -> Bool {
// Returns true if the text is empty or nil
return searchController.searchBar.text?.isEmpty ?? true
}
func filterContentForSearchText(_ searchText: String, scope: String = "All") {
filteredFriends = friendList.filter({( friend : Conversations) -> Bool in
return (friend.name?.lowercased().contains(searchText.lowercased()))!
})
mainTableView.reloadData()
}
func isFiltering() -> Bool {
return searchController.isActive && !searchBarIsEmpty()
}
extension NewConversationViewController: UISearchResultsUpdating {
// MARK: - UISearchResultsUpdating Delegate
func updateSearchResults(for searchController: UISearchController) {
filterContentForSearchText(searchController.searchBar.text!)
}
Pls tell me if you need more explanation.

Answer 1

Your the numberOfSection is equal to number of friends, that's why you have the number of action button equals to number of friends, try
func numberOfSections(in tableView: UITableView) -> Int {
return 2 // your button, and your friend list
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
if isFiltering() {
return 0 // hide button
}
return 1
} else if section == 1 {
if isFiltering() {
return filteredFriends.count
}
return friendList.count
}
return 0
}

Answer 2

Hide section 0 when you are using filtered list.
func numberOfSections(in tableView: UITableView) -> Int {
return 2 // Default 2 sections
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
if isFiltering() {
return 0
}
return 1
} else {
return friendList.count
}
return 0
}
