Swift UITextField 文本清除 TableViewCell 中的按钮操作 [英] Swift UITextField text clears with button action in TableViewCell

问题描述

我已经录制了我的屏幕并且这里是它的链接.进入细节

I have recorded my screen and here is the link to it. Going into details

1. 我有一个 tableView 部分，其中有一个 tableviewcell (PhoneCell) 和两个文本字段(一个是选择器视图输入，另一个是文本字段)和一个添加按钮.
2. 当点击添加按钮时，我将一个空电话附加到电话阵列(重复使用相同的 PhoneCell)并调用 tableView.reloadData() 方法.

1. I have a tableView section, in which there is a tableviewcell (PhoneCell) with two textfields (one is a pickerview input and other a textfield), and an Add Button.
2. When Add button is tapped, I am appending an empty phone to the array of phones (reusing the same PhoneCell) and calling tableView.reloadData() method.

问题:(
每当我点击添加按钮时，我输入的 textFields 文本都会被清除.我想保留它，并且最终应该能够在我点击 Save_Button

添加电话按钮操作代码:

func addUserPhone(userData: MyUserData) {
        self.user = userData

        var emptyPhoneDict:[String:String] = ["country":"", "number":""]

        if (user.phones?.count < 4) {
            var emptyPhone : MyUserPhoneNumber = MyUserPhoneNumber(dictionary: emptyPhoneDict)!
            emptyPhone.country = ""
            emptyPhone.number = ""
            user.phones?.append(emptyPhone)
        }
    }

在我的 PhoneCell.swift 类中，我有以下方法来处理数据和 indexPath 值

In my PhoneCell.swift class, I have the below method that is taking care of data and indexPath values

override func configure(withUser user: MyUserData, language: String, indexPath: NSIndexPath) {
        super.configure(withUser: user, language: language, indexPath: indexPath)

        configureCountryCodePicker()
        fetchCountryTeleCodeList()

        userInfo = user

        self.countryCode.borderStyle = .RoundedRect
        self.teleNumber.borderStyle = .RoundedRect

        if user.phones?.count == 0 {
            self.countryCode.text = ""
            self.teleNumber.text = ""
        }

        else {
            if let userPhoneInfo = user.phones {

                self.countryCode.text = userPhoneInfo[indexPath.row].country
                self.teleNumber.text = userPhoneInfo[indexPath.row].number

            }
        }
    }

编辑(添加 cellForRowAtIndexPath)

public override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        guard let section = Section(rawValue: indexPath.section) else {
            print("❌ Invalid section index.")
            return UITableViewCell()
        }

        let expanded = expandedCellPaths.contains(indexPath)

        var cell: ProfileCell?

        switch section {       

        case .ContactPhones:
            if contactCellExpanded == true {
                cell = tableView.dequeueReusableCellWithIdentifier("PhoneCell") as? PhoneCell
                (cell as? PhoneCell)?.dataSource = self

                if user.phones?.count == 4 {
                    (cell as! PhoneCell).addPhoneButton.hidden = true
                }
                else {
                    (cell as! PhoneCell).addPhoneButton.hidden = false
                }

            }
        case .ContactEmail:
            if contactCellExpanded == true {
                cell = tableView.dequeueReusableCellWithIdentifier("EmailCell") as? EmailCell
            }

        default:
            break
        }

        cell?.configure(withUser: user, language: languageCode, indexPath: indexPath)
        cell?.delegate = self

        return cell ?? UITableViewCell()

    }

编辑 2(添加 addPhoneButtonAction)

@IBAction func addPhoneButtonAction(sender: AnyObject) {
        self.dataSource?.addUserPhone(userInfo!)
    }

其中 dataSource 是 PhoneCellDataSource 协议类型的变量

Where dataSource is variable of type PhoneCellDataSource protocol

protocol PhoneCellDataSource : class {

    func fetchCountryTeleCodeList(completion:((XtraResult<NSArray, XtraError>) -> Void))
    func addUserPhone(userData: MyUserData)

}

我可以根据需要共享更多输入/代码.请帮忙.提前致谢！

I can share more inputs/code as required. Please help. Thanks in Advance!

推荐答案

我要回答我自己的问题 ;-)

I am going to answer my own question ;-)

TextFeilds 只是容纳一些数据(文本)的框.由于每次添加新行时我都会重用 Phonecell，因此我输入的文本会被删除.这是因为它不是存储/保存"在用户对象中.

TextFeilds are only boxes that accommodate some data (text). And since I was reusing the Phonecell each time I add a new row, the text I entered gets erased. This is because it is not "stored/saved" in the user object.

所以在我的 addPhoneButtonAction 方法中，我添加了这个 -

So in my addPhoneButtonAction method, I added this -

@IBAction func addPhoneButtonAction(sender: AnyObject) {
        userInfo?.phones![myIndexPath!.row].country = countryCode.text!
        userInfo?.phones![myIndexPath!.row].number = teleNumber.text!

        self.dataSource?.addUserPhone(userInfo!)
    }

其中 myIndexPath 是行的 indexPath :-)

Where myIndexPath is the indexPath of the row :-)
