Swift UISearchController wenn Element suchen Suchleiste ist immer noch

Question

Ich habe zwei Probleme mit UISearchController. ich dieses Setup verwenden für UISearchController:

var resultSearchController = UISearchController(searchResultsController: nil) 

override func viewDidLoad() { 
    super.viewDidLoad() 

    resultSearchController = UISearchController(searchResultsController: nil) 
    resultSearchController.searchResultsUpdater = self 
    resultSearchController.dimsBackgroundDuringPresentation = false 
    resultSearchController.hidesNavigationBarDuringPresentation = false 
    resultSearchController.searchBar.placeholder = "Traži.." 
    resultSearchController.searchBar.sizeToFit() 
    tableView.tableHeaderView = resultSearchController.searchBar 

    refreshControl = UIRefreshControl() 
    refreshControl!.attributedTitle = NSAttributedString(string: "Učitaj podatke..") 
    refreshControl!.backgroundColor = UIColor(red:1, green:0.48, blue:0, alpha:0.3) 
    refreshControl!.tintColor = UIColor.whiteColor() 
    refreshControl!.addTarget(self, action: #selector(ArticleTableViewController.getArticleData), forControlEvents: UIControlEvents.ValueChanged) 
    tableView.addSubview(refreshControl!) 
} 

Erstes Problem

wenn ich auf Suchleiste Textfeld, UIRefreshControl zeigt aber es sollte nicht:

Zweite Problem

Wenn ich nach einem Element suche und darauf klicke, benutze ich das Storyboard-Segment, um das Element im neuen Viewcontroller zu öffnen, aber das Problem ist, dass die Suchleiste immer noch auf dem neuen VC vorhanden ist (das erste Bild sucht, das zweite Bild zeigt das neue VC geöffnet)):

Answer 1

fand ich dieses Lösung:

override func viewDidLoad() { 
    super.viewDidLoad() 

    resultSearchController = UISearchController(searchResultsController: nil) 
    resultSearchController.searchResultsUpdater = self 
    resultSearchController.dimsBackgroundDuringPresentation = false 
    resultSearchController.hidesNavigationBarDuringPresentation = false 
    resultSearchController.searchBar.placeholder = "Traži.." 
    resultSearchController.searchBar.sizeToFit() 
    tableView.tableHeaderView = resultSearchController.searchBar 

    refreshControl = UIRefreshControl() 
    refreshControl!.attributedTitle = NSAttributedString(string: "Učitaj podatke..") 
    refreshControl!.backgroundColor = UIColor(red:1, green:0.48, blue:0, alpha:0.3) 
    refreshControl!.tintColor = UIColor.whiteColor() 
    refreshControl!.addTarget(self, action: #selector(ArticleTableViewController.getArticleData), forControlEvents: UIControlEvents.ValueChanged) 
    tableView.addSubview(refreshControl!) 


    // this hide search bar on next VC, first problem 
    self.definesPresentationContext = true 
    // second problem 
    tableView.contentOffset = CGPointMake(0, CGRectGetHeight(resultSearchController.searchBar.frame)); 

} 

Answer 2

sein Mögen Sie einen UISearchBar anstelle des UISearchController verwenden sollte? Versuchen Sie diesen Code:

ViewController.swift

import UIKit 

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate { 

@IBOutlet var searchBar: UISearchBar! 
@IBOutlet var tableView: UITableView! 


override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
    tableView.dataSource = self 
    tableView.delegate = self 
    searchBar.delegate = self 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return 40 
} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCellWithIdentifier("cell") 
    cell?.textLabel?.text = "\(indexPath.row)" 
    return cell! 
} 

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    let newViewController = UIViewController() 
    newViewController.view.backgroundColor = UIColor.whiteColor() 
    newViewController.title = "\(indexPath.row)" 
    navigationController?.pushViewController(newViewController, animated: true) 
} 


func searchBar(searchBar: UISearchBar, textDidChange searchText: String) { 
    NSLog(searchText) 
} 
}
