searchBar 필터링 된 tableViewCells didSelectItemAt navigationBar의 indexPath 표시 제목

Question

enter image description here searchBar 필터링 된 tableView 셀에서 didSelectRowAtIndexPath를 구현하는 데 문제가 있습니다. 검색 막대 textDidChange를 기반으로 tableView 목록을 업데이트하고 다른 ViewController에 대한 표시 세부를 수행하면 탐색 모음 제목은 항상 필터링되지 않은 tableViews indexPath 0을 표시합니다. 즉, 탐색 제목에 텍스트를 표시하고 싶습니다. 검색 결과 tableView의 didSelectAtIndex (필터링되지 않은 tableView의 원본 indexPath 셀 텍스트가 아님). 희망적으로 그것은 의미가 있고, 미리 감사드립니다!

// viewDidLoad method 
    override func viewDidLoad() { 
     super.viewDidLoad() 

     searchBar.searchBarStyle = UISearchBarStyle.prominent 
     searchBar.placeholder = " Search Places..." 
     searchBar.sizeToFit() 
     searchBar.isTranslucent = false 
     searchBar.backgroundImage = UIImage() 
     searchBar.delegate = self 
     searchBar.returnKeyType = UIReturnKeyType.done

    } 

    var placeList = [Place]()

        self.placesDictionary[addedBy] = place 
        self.placeList.insert(place, at: 0) 
       } 
       //this will crash because of background thread, so lets call this on dispatch_async main thread 
       DispatchQueue.main.async(execute: {

Answer 1

위로 오는 ViewController에서 문자열을 만듭니다.

class CurrentUserPlaceDetailsVC: UIViewController { 
    var navigationTitle: String? 

    override func viewDidLoad(){ 
     super.viewDidLoad() 
     self.navigationItem.title = navigationTitle 
    } 
} 

지금 대신 내비게이션 바에 직접 제목을 할당하는 당신은 당신의 ViewController의있는 viewDidLoad 방법에 내비게이션 바 먼저 해당 문자열에 다음을 할당해야합니다.

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
     let placeDetailsVC = CurrentUserPlaceDetailsVC() 
     // Get Cell Label 
     placeDetailsVC.navigationTitle = placeList[indexPath.row].place 
     show(placeDetailsVC, sender: self) 

    }
