I'm working on a project in swift 3 and I have a specific UIViewController where I have a UITableView and as to populate data on its cell, the data is get from the server and I assign it to an array of the type JSON. I wants to implement a custom UISearchBar as to filter these data. I have worked partially on code and its as bellow.
import UIKit
import SwiftyJSON
import SDWebImage
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource,UISearchResultsUpdating,UISearchBarDelegate {
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var searchBar: UISearchBar!
var searchActive : Bool?
var selectedCategoryList = [JSON?]()
var filterSelectedCategoryList = [JSON?]()
var lab :String?
let searchController = UISearchController(searchResultsController: nil)
override func viewDidLoad() {
super.viewDidLoad()
passJson()
self.searchBar.delegate = self
self.tableView.reloadData()
}
func updateSearchResults(for searchController: UISearchController) {
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filterSelectedCategoryList = selectedCategoryList.filter { titles in
return (titles?["healerName"].stringValue.lowercased().contains(searchText.lowercased()))!
}
tableView.reloadData()
print("Array : ", filterSelectedCategoryList)
}
func passJson() {
let path : String = Bundle.main.path(forResource: "JsonFile", ofType: "json") as String!
let jsonData = NSData(contentsOfFile: path) as NSData!
let readableJson = JSON(data: jsonData as! Data, options: JSONSerialization.ReadingOptions.mutableContainers, error: nil)
let json = readableJson
print(json)
let selectedItemArray = json["itemList"].arrayValue
self.selectedCategoryList = selectedItemArray
print("new prints",self.selectedCategoryList)
tableView.reloadData()
// print( "Count",selectedItemArray?.count as Any)
self.count = self.selectedCategoryList.count
print(self.count)
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.searchController.isActive && self.searchBar.text != ""{
return filterSelectedCategoryList.count
}else{
return selectedCategoryList.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! TableViewCell
if count > 0 {
if self.searchController.isActive && self.searchBar.text != ""{
cell.label.text = filterSelectedCategoryList[indexPath.row]?["healerName"].stringValue
}else{
cell.label.text = selectedCategoryList[indexPath.row]?["healerName"].stringValue
cell.textLabel?.text = selectedCategoryList[indexPath.row]?["id"].stringValue
//cell.textLabel?.text=
self.lab = cell.textLabel?.text
cell.textLabel?.isHidden = true
}
}
return cell
}

From your code you are working with UISearchBar
not with UISearchController
, so you need to only compare searchBar
text in methods numberOfRowsInSection
and in cellForRowAt
, don't compare searchController.isActive
with it.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.searchBar.text != ""{
return filterSelectedCategoryList.count
}else{
return selectedCategoryList.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! TableViewCell
if self.searchBar.text != ""{
cell.label.text = filterSelectedCategoryList[indexPath.row]?["healerName"].stringValue
}else{
cell.label.text = selectedCategoryList[indexPath.row]?["healerName"].stringValue
cell.textLabel?.text = selectedCategoryList[indexPath.row]?["id"].stringValue
//cell.textLabel?.text=
self.lab = cell.textLabel?.text
cell.textLabel?.isHidden = true
}
return cell
}
