Question

我有一个TableView，基本上用户可以从名单列表中搜索。我有搜索设置，所以他们可以输入一个名字，然后搜索那个人。

当他们选择一个单元格时，它所做的只是将名称字符串传递给下一个视图。当没有人搜索时它完全正常，你只需在表格中选择一个单元格。但是，当您搜索名称，然后选择时，您点击该单元格，它将变为灰色。然后它加载下一个显示，但不显示它。然后，当我点按搜索栏上的“取消”时，它会崩溃该应用。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
    }

}

提前感谢您的任何建议。
