ios - tableView.dequeueReusableCell 打开错误的ViewController

Question

我有一个数组，我为每个数组项创建了一个单独的 vc，tableView.dequeueReusableCell 显示错误的 vc。我读到这是因为该单元格是可重复使用的，并且它保留了先前选择的数组中的数据。你能帮我解决一下吗？

我的代码是:

import UIKit

class Nicosia: UIViewController, UITableViewDelegate, UITableViewDataSource {
    let nicosiaPlaces = ["Famagusta Gate", "Laiki Geitonia", "Ledra Street","Omeriye Hamam","Cyprus Museum","Venetian Walls","The House of Hatjigeorgakis Kornessios","Byzantine Art Museum","Archbishop's Palace","Liberty Monument","The Faneromeni Church","Nicosia International Conference Center"]

     var identities = ["Famagusta Gate", "Laiki Geitonia", "Ledra Street","Omeriye Hamam","Cyprus Museum","Venetian Walls","The House of Hatjigeorgakis Kornessios","Byzantine Art Museum","Archbishop's Palace","Liberty Monument","The Faneromeni Church","Nicosia International Conference Center"]

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return nicosiaPlaces.count
    }

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

        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell")
        let city = nicosiaPlaces [indexPath.row]
        cell?.textLabel?.text = city
        return cell!
    }

    func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {

        let vcName = identities[indexPath.row]
        let viewController = storyboard?.instantiateViewController(withIdentifier: vcName)
        self.navigationController?.pushViewController(viewController!, animated: true)
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
}

你的意思是didDeselectRowAt，而不是dequeueReusableCell。

问题是您需要 didSelectRowAt，而不是 didDeselectRowAt。
