поиска UISearchController для элементов массива внутри другого массива с помощью Swift 2

Question

У меня есть контроллер Tableview с Searchbar и я хочу, чтобы искать в пунктах внутри массива в моем примере я хочу, чтобы искать элементы teamsArr внутри лиг массива

Теперь мой код поиск штраф в Legue Имя не команды имя

мой код:

import UIKit 

struct Legue { 
var name:String 
var num:Int 
var teamsArr:[String] 
} 

class Table1ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource,UISearchResultsUpdating { 

@IBOutlet var myTable: UITableView! 

let cellID="MyCellID" 
var Legues:[Legue]=[] 
var searchController=UISearchController(searchResultsController: nil) 
var filterLegues:[Legue]=[] 





func filterContentForSearch(searchText:String,scope:String="All2") 
{ 
    filterLegues=Legues.filter{leg in 
     return leg.name.containsString(searchText) **\\ Here search only in Legue name ,but i want to search in teams name** 
    } 


    myTable.reloadData() 
} 
override func viewDidLoad() { 
    super.viewDidLoad() 

    myTable.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellID) 

    myTable.delegate=self 
    myTable.dataSource=self 
    Legues=self.loadData() 

    searchController.searchResultsUpdater=self 

    searchController.dimsBackgroundDuringPresentation=false 
    definesPresentationContext=true 
    myTable.tableHeaderView=searchController.searchBar 
    searchController.hidesNavigationBarDuringPresentation=false 


} 




func loadData()->[Legue] 
{ 
    let arrlegue=[Legue(name:"Spain",num: 3,teamsArr: ["Barcelona","Atletico Madrid","Real Madrid"]),Legue(name:"Saudi",num: 4,teamsArr: ["Ahli","Hilal","AlNaser","AlEtihad"]),Legue(name:"England",num: 2,teamsArr:["Lestercity","Man City"]),Legue(name:"Italy",num: 5,teamsArr: ["Juventus","Napoli","AS Roma","Internazionale","AC Milano"])] 

    return arrlegue 
} 

override func prefersStatusBarHidden() -> Bool { 
    return true 
} 

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

    if searchController.active && searchController.searchBar.text != "" 
    { 
    let x=filterLegues[section].teamsArr.count 
    return x 
    } 

    let x=Legues[section].teamsArr.count 
    return x 
} 

func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    if searchController.active && searchController.searchBar.text != "" 
    { 
    return filterLegues.count 
    } 
    else 
    { 
     return Legues.count 
    } 
} 
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? { 
    if searchController.active && searchController.searchBar.text != "" 
    { 
    return filterLegues[section].name 
    } 
    else 
    { 
     return Legues[section].name 
    } 
} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 

    let cell=myTable.dequeueReusableCellWithIdentifier(cellID, forIndexPath: indexPath) 
    if searchController.active && searchController.searchBar.text != "" 
    { 
    cell.textLabel?.text="\(filterLegues[indexPath.section].teamsArr[indexPath.row])" 
     cell.imageView?.image=UIImage(named: filterLegues[indexPath.section].name) 
    } 
    else 
    { 
    cell.textLabel?.text="\(Legues[indexPath.section].teamsArr[indexPath.row])" 
    cell.imageView?.image=UIImage(named: Legues[indexPath.section].name) 
    } 
     return cell 
} 

func tableView(tableView: UITableView, canMoveRowAtIndexPath indexPath: NSIndexPath) -> Bool { 
    return true 
} 

func tableView(tableView: UITableView, moveRowAtIndexPath sourceIndexPath: NSIndexPath, toIndexPath destinationIndexPath: NSIndexPath) { 

    if sourceIndexPath != destinationIndexPath 
    { 
    let itemToMove=Legues[sourceIndexPath.section] 
    Legues.removeAtIndex(sourceIndexPath.section) 
    Legues.insert(itemToMove, atIndex: destinationIndexPath.section) 

    myTable.reloadData() 
    } 
    } 

@IBAction func editButton(sender: UIBarButtonItem) { 

    myTable.editing=true 
} 

func updateSearchResultsForSearchController(searchController: UISearchController) 
{ 
    filterContentForSearch(searchController.searchBar.text!) 


} 

}

Answer 1

Это должно сделать трюк

Свести teamArray лиги и фильтровать

func filterContentForSearch(searchText:String,scope:String="All") 
{ 
    filterLegues = arrlegue.filter{$0.teamsArr.contains{$0.localizedCaseInsensitiveContainsString("Juv")}} 

    myTable.reloadData() 
} 

Answer 2

Вашего фильтр правильно, но вы не связывание вида делегата таблицы должным образом. Вы должны использовать отфильтрованный массив как источник данных в виде таблицы на cellForRowAtIndexPath.

func filterContentForSearch(searchText:String,scope:String="All") 
{ 
    filterLegues = Legues.filter{leg in return leg.name.containsString(searchText) || leg.teamsArr.filter{$0.containsString(searchText)}.count > 0 } 
} 

И таким образом, вы можете искать как в имени и команды

мой код так, и это работает:
