search之后select单元格不会直观地进行，但加载下一个视图Swift Xcode

我有一个TableView，这基本上是为用户从名称列表中search。 我有search设置，所以他们可以键入一个名称，它会search该人。

当他们select一个单元格时，它所做的就是将名称string转移到下一个视图。 当没有人search时，它工作得很好，你只需要在表格中select一个单元格。 然而，当你search一个名字，然后select，你点击单元格，它变成灰色。 然后加载下一个显示，但不显示它。 然后当我点击search栏上的取消，它崩溃的应用程序。 我不知道该怎么做/这个错误是什么。

var appleProducts = ["I am using a custom name"] var filteredAppleProducts = [String]() var resultSearchController = UISearchController() override func viewDidLoad() { super.viewDidLoad() self.loadNames() self.resultSearchController = UISearchController(searchResultsController: nil) self.resultSearchController.searchResultsUpdater = self self.resultSearchController.dimsBackgroundDuringPresentation = false self.resultSearchController.searchBar.sizeToFit() self.resultSearchController.searchBar.placeholder = "Type Name Here" self.tableView.tableHeaderView = self.resultSearchController.searchBar self.tableView.reloadData() } override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 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! AddSearchTableViewCell if (self.resultSearchController.active) { cell.name.text = self.filteredAppleProducts[indexPath.row] return cell } else { cell.name.text = self.appleProducts[indexPath.row] return cell } } 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() } override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { // let indexPath = tableView.indexPathForSelectedRow let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as! AddSearchTableViewCell print("Going to Did Select Name!") self.performSegueWithIdentifier("didSelectName", sender: currentCell.name.text) } override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { if segue.identifier == "didSelectName" { let completeSignUpVC = segue.destinationViewController as! AddUpViewController let selectedRowIndex = self.tableView.indexPathForSelectedRow let currentCell = tableView.cellForRowAtIndexPath(selectedRowIndex!) as! AddSearchTableViewCell completeSignUpVC.userObjectId = currentCell.name.text } } 

提前感谢您的任何build议。
