ios - 在 iOS 中从 NSArray 的 UITableView 删除一行并更新 UI

Question

我需要删除一个表格 View 单元格。删除操作将从服务器中删除数据并成功弹出。但 TableView 中的单元格不会被删除。我们如何从 NSArray 中删除数据？ [.remove(at: indexpath.row)] 不适用于 NSArray。谁能帮我解决这个问题？

import UIKit
import Alamofire

class BankDashController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    var dictData:NSArray = NSArray()
    var dictData2 = [String]()
    var appDictionary:NSDictionary!
    var strId: NSArray?
    var appDictionary1: NSNumber?
    var TokenSet  = UserDefaults.standard.object(forKey: "tokenSetAll")

    @IBOutlet weak var bankTable: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.getTaskData()

        bankTable.delegate = self
        bankTable.dataSource = self
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.getTaskData()
    }

    @IBAction func addBankDetails(_ sender: Any) {

使 dictData 数组可变 var dictData:NSMutableArray = NSMutableArray()

然后尝试dictData.removeObject(at:indexPath.row)
