UISearchController以快捷方式顯示在nextView中

我以編程方式將UISearchController簡單地執行到我的UITableViewController中。以下是我的完整代碼：UISearchController以快捷方式顯示在nextView中

import UIKit 

class TableViewController: UITableViewController, UISearchResultsUpdating { 

    let appleProducts = ["Mac","iPhone","Apple Watch","iPad"] 
    var filteredAppleProducts = [String]() 
    var resultSearchController = UISearchController() 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     self.resultSearchController = UISearchController(searchResultsController: nil) 
     self.resultSearchController.searchResultsUpdater = self 
     self.resultSearchController.dimsBackgroundDuringPresentation = false 
     self.resultSearchController.searchBar.sizeToFit() 

     self.tableView.tableHeaderView = self.resultSearchController.searchBar 

     self.tableView.reloadData() 
    } 

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

    // MARK: - Table view data source 

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
     // #warning Incomplete implementation, return the number of sections 
     return 1 
    } 

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     // #warning Incomplete implementation, return the number of rows 
     if (self.resultSearchController.active){ 
      return self.filteredAppleProducts.count 
     }else{ 
      return self.appleProducts.count 
     } 
    } 


    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell? 

     if (self.resultSearchController.active) 
     { 
      cell!.textLabel?.text = self.filteredAppleProducts[indexPath.row] 

      return cell! 
     } 
     else 
     { 
      cell!.textLabel?.text = self.appleProducts[indexPath.row] 

      return cell! 
     } 
    } 

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 

     let vc = self.storyboard!.instantiateViewControllerWithIdentifier("Detail") as! DetailViewController 
     self.navigationController!.pushViewController(vc, animated: true) 
    } 
    func updateSearchResultsForSearchController(searchController: UISearchController){ 

     self.filteredAppleProducts.removeAll(keepCapacity: false) 

     let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!) 
     let array = (self.appleProducts as NSArray).filteredArrayUsingPredicate(searchPredicate) 
     self.filteredAppleProducts = array as! [String] 

     self.tableView.reloadData() 
    } 

}

我resultSearchController工作完全正常，但當我點擊任一單元格，然後UISearchController正出現在我的下一個視圖也如入下圖：
