为index.row的所选键重新保存NSUserDefaults值

I have array NSUserDefaults type :

我有阵列NSUserDefaults类型:

    let userValue = ["name": self.nameLbl.text ?? "", "lastName": self.lastNameLbl.text ?? "", "city": cityLbl.text ?? ""] as! [String : String]
    var userArray = UserDefaults.standard.array(forKey: "userInfo") as? [[String: String]] ?? []
    UserDefaults.standard.set(userArray, forKey: "userInfo")


  And save this array in first `ViewController` 

In second ViewController Im display this array in UITAbleView

在第二个ViewController中我在UITAbleView中显示这个数组

 class ...

 var userInfo = [[String:String]]()

 override func viewDidLoad() {
    super.viewDidLoad()
 userInfo = UserDefaults.standard.array(forKey: "userInfo") as? [[String: String]] ?? []
}

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! UserTableViewCell

 var userItem = userInfo[indexPath.row]
 cell.nameLbl?.text = item["name"]
 cell.lastNameLbl.text = item["lastName"]
 cell.cityLbl.text = item["city"]

and under UITAbleView I have 3 UIextField's and UIButton for the opportunity to change user information

在UITAbleView下我有3个UIextField和UIButton,可以更改用户信息

When user pass text in UIextField's I want to resave value for key

当用户在UIextField中传递文本时,我想为key重新保存值

How can I remove selected name and save new name to correctly user??

如何删除所选名称并将新名称保存到正确的用户?

Im update code in cellForRowAt

我在cellForRowAt中更新代码

var userItem = userInfo[indexPath.row]
 cell.nameLbl?.text = item["name"]
 cell.lastNameLbl.text = item["lastName"]
 cell.cityLbl.text = item["city"]

item["name"] = cell.nameLbl?.text


  var maArray = UserDefaults.standard.array(forKey: "userInfo") as? [[String: String]] ?? []

  item.updateValue(cell.nameLbl?.text, forKey: "name")
        maArray.append(item)

But its not save

但它不能保存

You can fetch your complete array from Userdefaults

您可以从Userdefaults获取完整的数组

Now do is that get the new values from textField and replace that at the specific indexPath.row

现在做的是从textField获取新值并在特定的indexPath.row处替换它

For e.g:

var userInfo = [[String:String]]()

 let data  = userInfo[indexPath.row]
 data["name"] = txtName.text
 data["address"] = txtAddress.text

And now store this full array back to userDefaults and you will get the updated Result every Time.

现在将此完整数组存储回userDefaults,您将每次都获得更新的结果。

Hope this helps.

希望这可以帮助。

Edit with reference to the code

Do like this:

这样做:

var maArray = UserDefaults.standard.array(forKey: "userInfo") as? [[String: String]] ?? []

    let innerData = maArray[indexPath.row]

    innerData["name"] = cell.nameLbl?.text
    innerData["lastName"] = cell.lastNameLbl.text
    innerData["city"] = cell.cityLbl.text


    // And save the maArray back to userDefaults
