当UISearchController处于活动状态时在tableview中选择单元格时，不存在下一个视图？

Question

我已经做了一个tableview，你可以选择一个单元格，然后viewcontroller会执行一个segue到下一个视图，当你不使用searchcontroller的时候，它工作得很好。 然后，当您使用searchcontroller时，它会按照它应该过滤tableview，并且在didSelectRowAtIndexPath中调用segue，并调用prepareForSegue。那么问题是它应该延续的视图不会被呈现？我可以看到连接到视图的类中的代码正在运行，所以执行了segue，它只是不遵循的视图。我缺少什么

class CompanyListViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchResultsUpdating { 

@IBOutlet weak var tableView: UITableView! 

let objectMapper = AWSDynamoDBObjectMapper.defaultDynamoDBObjectMapper() 

var activityIndicatorView: SWActivityIndicatorView! 

var resultSearchController: UISearchController! 

var allCompanies: [Company] = [] 
var filteredCompanies = [Company]() 

override func viewDidLoad() { 
    super.viewDidLoad() 


    // set delegates 
    tableView.delegate = self 
    tableView.dataSource = self

    // initialize activity indicator view 
    self.activityIndicatorView = SWActivityIndicatorView(frame: CGRect(x: 0, y: 0, width: 30, height: 30))

    activityIndicatorView.color = UIColor.lightGrayColor() 
    self.view.addSubview(activityIndicatorView) 
    self.activityIndicatorView.center = self.view.center 
    activityIndicatorView.startAnimating()

    fetchAllRecords({(errors: [NSError]?) -> Void in if errors != nil {print(errors)}})

     let selectedRow = indexPath!.row 
     let profileVC = segue.destinationViewController as! ProfileViewController 

     if resultSearchController.active{

     } else { 

      profileVC.company = allCompanies[selectedRow] 

     } 
    } 

} 

}

控制台是这样说，但我不知道这有什么用呢？

在这里被TableView中的与搜索栏control.You的例子应该删除didSelectRowAtIndexPath方法的方法和使用prepareForSegue方法确定TableView.Like这个选定的行...

例子：

import UIKit 

class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate 
{ 

@IBOutlet weak var SerchBar: UISearchBar! 
@IBOutlet weak var TableView: UITableView! 


var searchActive : Bool = false 
var data = ["San Francisco","New York","San Jose","Chicago","Los Angeles","Austin","Seattle"] 
var filtered:[String] = [] 

override func viewDidLoad() 
{ 
    super.viewDidLoad() 

} 

private func numberOfSectionsInTableView(tableView: UITableView) -> Int 
{ 
    return 1 
} 
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int 
{ 
    if(searchActive) 
    { 
     return filtered.count 
    } 
    return data.count; 
} 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 
{ 
    let cell = self.TableView.dequeueReusableCell(withIdentifier: "Cell") as! TableViewCell 
    if(searchActive) 
    { 
     cell.Label.text = filtered[indexPath.row] 
    } 
    else 
    { 
     cell.Label.text = data[indexPath.row] 
    } 

    return cell 
} 

override func prepare(for segue: UIStoryboardSegue, sender: Any!) 
{ 
    if let cell = sender as? TableViewCell 
    { 
     let i = TableView.indexPath(for: cell)!.row 
     if segue.identifier == "segue1" 
     { 
      if(searchActive) 
      { 
       let name1 = segue.destination as! SecondView 
       name1.str = self.filtered[i] 
      } 
      else 
      { 
       let name1 = segue.destination as! SecondView 
       name1.str = self.data[i] 

      } 
     } 
    } 
} 

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{ 
    filtered = data.filter({ (text) -> Bool in 
     let tmp: NSString = text as NSString 
     let range = tmp.range(of: searchText, options: .caseInsensitive) 
     return range.location != NSNotFound 
    }) 
    if(filtered.count == 0) 
    { 
     searchActive = false; 
    } 
    else 
    { 
     searchActive = true; 
    } 
    self.TableView.reloadData() 
} 

func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) 
{ 
    searchActive = true; 
} 

func searchBarTextDidEndEditing(_ searchBar: UISearchBar) 
{ 
    searchActive = false; 
} 

func searchBarCancelButtonClicked(_ searchBar: UISearchBar) 
{ 
    searchActive = false; 
} 

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) 
{ 
    searchActive = false; 
} 

override func didReceiveMemoryWarning() 
{ 
    super.didReceiveMemoryWarning() 
} 
} 

你SecondView类是：

import UIKit 

class SecondView: UIViewController 
{ 
@IBOutlet weak var label: UILabel! 
var str:String! 

override func viewDidLoad() 
{ 
    super.viewDidLoad() 
    self.label.text = str 
} 

override func didReceiveMemoryWarning() 
{ 
    super.didReceiveMemoryWarning() 
} 

} 

和你TableViewCell是：

import UIKit 

class TableViewCell: UITableViewCell 
{ 
@IBOutlet weak var Label: UILabel! 
override func awakeFromNib() 
{ 
    super.awakeFromNib() 
} 

override func setSelected(_ selected: Bool, animated: Bool) 
{ 
    super.setSelected(selected, animated: animated) 

} 

}
