存储在数组中并显示在uitableview中的uisearchbar结果干扰了我的didselectrowat indexpath方法(swift)

我有一个uitableview,它由titles数组中的项填充,我设置了它,以便在调用didselectrowat indexpath时,名为arrayindex的变量将更改为indexpath,下一个vc的内容也将更改。

因此,如果用户点击:

• 第0行>vc将具有标题0、定义0和链接0
• 第12行>VC将具有标题12、定义12和链接12

但是,我有一个搜索栏,它将筛选的结果存储在search results数组中,并在tableview中显示。执行搜索时,数组索引将不再对应,因此如果搜索查询将tableview更改为

• 第0行的标题4>VC将具有标题0、定义0和链接0
• 第1行的标题5>VC将具有标题1、定义1和链接1
• 第2行的标题18>VC将具有标题2、定义2和链接2

我理解为什么它不能按预期工作,但我不知道如何更新我的逻辑来修复它。思想?这是我的代码:

列表控制器:

import UIKit

var arrayIndex = 0 // is used in DefinitionController to determine which title/definition/link to show.
var isSearching = false

class ListController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate {

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

    // Search Delegate
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        if searchText == "" {
            isSearching = false
            tableView.reloadData()
        } else {
            isSearching = true
            searchResults = (titles.filter { $0.lowercased().contains(searchText.lowercased()) })
            tableView.reloadData()
        }
    }

    //Table Delegate
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        if isSearching == true {
            // code to run if searching is true
        } else {
            arrayIndex = indexPath.row // assigns the value of the selected tow to arrayIndex
        }

        performSegue(withIdentifier: "segue", sender: self)
        tableView.deselectRow(at: indexPath, animated: true)
    }

    // Table Data Source
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if isSearching == true {
            return searchResults.count
        } else {
            return titles.count
        }
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        // Cell Data Source
        let cell = UITableViewCell()

        if isSearching == true {
            cell.textLabel?.text = searchResults[indexPath.row]
        } else {
            cell.textLabel?.text = titles[indexPath.row]
        }

        // Cell Visual Formatting
        cell.backgroundColor = UIColor(red:0.05, green:0.05, blue:0.07, alpha:0)
        cell.textLabel?.textColor = UIColor.white
        cell.textLabel?.font = UIFont(name: "Raleway", size: 18)
        cell.accessoryType = UITableViewCellAccessoryType.disclosureIndicator

//        if (cell.isSelected) {
//            cell.backgroundColor = UIColor.cyan
//        }else{
//            cell.backgroundColor = UIColor.blue
//        }

        return cell
    }


    override func viewDidLoad() {
        super.viewDidLoad()
        self.title = "\(titles.count) Definitions"

        // TextField Color Customization
        let searchBarStyle = searchBar.value(forKey: "searchField") as? UITextField
        searchBarStyle?.textColor = UIColor.white
        searchBarStyle?.backgroundColor = UIColor(red:1.00, green:1.00, blue:1.00, alpha:0.05)

    }   
}

定义控制器:

import UIKit

class DefinitionController: UIViewController {

    @IBOutlet var definitionTitle: UILabel!
    @IBOutlet var definitionBody: UILabel!
    @IBOutlet var definitionSources: UILabel!

    // Open link in Safari
    @objc func tapFunction(sender:UITapGestureRecognizer) {
        print("tap working")
        if let url = URL(string: "\(links[arrayIndex])") {
            UIApplication.shared.openURL(url)
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        definitionTitle.text = titles[arrayIndex]
        definitionBody.text = definitions[arrayIndex]


        self.title = "" // Used to be \(titles[arrayIndex])

        // Sources Link
        let tap = UITapGestureRecognizer(target: self, action: #selector(DefinitionController.tapFunction))
        definitionSources.addGestureRecognizer(tap)

    }

}
