swift tableview with sections cannot use searchbar - ios

Question

i have created a tableview with searchbar. My dataset looks like the following :
var data : [[ContactObject]] = []
Everything is working well but if i'm trying to search it doesnt really work.
Here is my search method:
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filteredGroups = self.data[1].filter({(bo: ContactObject ) -> Bool in
return bo.name!.lowercased().contains(searchText.lowercased())
})
filteredUsers = self.data[2].filter({(bo: ContactObject ) -> Bool in
return bo.name!.lowercased().contains(searchText.lowercased())
})
self.filteredData.append(self.myStories)
self.filteredData.append(self.filteredGroups )
self.filteredData.append(self.filteredUsers)
collectionView.reloadData()
}
i'm adding self.myStories always because its static content in my tableview. To show the suitable data i have extended my cell for item at like the following:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if !isFiltering(){
if data[indexPath.section][indexPath.row].name == "Freunde" || data[indexPath.section][indexPath.row].name == "Interessen (öffentlich)"{
var cell1 = tableView.dequeueReusableCell(withIdentifier: "selectStory", for: indexPath) as! StorySelectionTableViewCell
cell1.label.text = data[indexPath.section][indexPath.row].name
cell1.select.setOn(false, animated: true)
cell1.select.tag = indexPath.row
cell1.select.addTarget(self, action: #selector(handleSwitch), for: .valueChanged)
return cell1
}
var cell = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath) as! ContactsTableViewCell
cell.select.tag = indexPath.row
cell.thumb.layer.masksToBounds = false
cell.thumb.layer.cornerRadius = cell.thumb.frame.height/2
cell.thumb.clipsToBounds = true
cell.name.text = data[indexPath.section][indexPath.row].name
cell.select.addTarget(self, action: #selector(handleButtonPress), for: .touchDown)
if data[indexPath.section][indexPath.row].imageUrl != "" && data[indexPath.section][indexPath.row].imageUrl != nil{
let url = URL(string: data[indexPath.section][indexPath.row].imageUrl!)
cell.thumb.kf.setImage(with: url)
}
return cell
}else{
if filteredData[indexPath.section][indexPath.row].name == "Freunde" || filteredData[indexPath.section][indexPath.row].name == "Interessen (öffentlich)"{
var cell1 = tableView.dequeueReusableCell(withIdentifier: "selectStory", for: indexPath) as! StorySelectionTableViewCell
cell1.label.text = filteredData[indexPath.section][indexPath.row].name
cell1.select.setOn(false, animated: true)
cell1.select.tag = indexPath.row
cell1.select.addTarget(self, action: #selector(handleSwitch), for: .valueChanged)
return cell1
}
var cell = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath) as! ContactsTableViewCell
cell.select.tag = indexPath.row
cell.thumb.layer.masksToBounds = false
cell.thumb.layer.cornerRadius = cell.thumb.frame.height/2
cell.thumb.clipsToBounds = true
cell.name.text = filteredData[indexPath.section][indexPath.row].name
cell.select.addTarget(self, action: #selector(handleButtonPress), for: .touchDown)
if data[indexPath.section][indexPath.row].imageUrl != "" && data[indexPath.section][indexPath.row].imageUrl != nil{
let url = URL(string: filteredData[indexPath.section][indexPath.row].imageUrl!)
cell.thumb.kf.setImage(with: url)
}
return cell
}
}
and my numbersOfRowsInSection like this:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if isFiltering(){
return filteredData[section].count
}
return data[section].count
}
the result is no matter which word i'm typing in, my third section (self.filteredUsers) is always empty and self.filteredGroups always complete.

Answer 1

This is just a guess, but I think you should not append to filteredData here:
self.filteredData.append(self.myStories)
self.filteredData.append(self.filteredGroups )
self.filteredData.append(self.filteredUsers)
This will make filteredData longer and longer, and the cellForRowAt only makes use of the first three items. You should instead replace the whole array with the three subarrays:
filteredData = [myStories, filteredGroups, filteredUsers]
The other thing I noticed is that you are reloading a collection view after the three lines above, but the search bar seems to be installed on a table view. Maybe you should be reloading the table view instead, or this is a mere typo.
