사용자 지정 UISearchBar에서 필터 데이터를 가져 오지 않습니다.

Question

신속한 3에서 프로젝트를 진행하고 있으며 UITableView가 있고 해당 셀의 데이터를 채우는 특정 UIViewController가 있으며 데이터는 서버에서 가져와 할당됩니다. 그것은 JSON 타입의 배열이다. 이 데이터를 필터링하기 위해 사용자 지정 UISearchBar를 구현하려고합니다. 나는 부분적으로 코드와 그것의 노호로 일했다. 코드에서

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 
     } 

Answer 1

당신은 UISearchBar하지 UISearchController와 함께 노력하고 있습니다, 그래서 당신은 그것으로 searchController.isActive을 비교하지 않는다, 단지 방법 numberOfRowsInSection 및 cellForRowAt에서의 searchBar 텍스트를 비교해야합니다.

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 
}
