如何在 swift 的 tableview 中编辑行而不添加另一行

Question

我从 JSON 显示 firstVC Tableview 中的所有地址。我在 secondVC tableview 中显示的相同地址在这里我有一个选项编辑。所以如果我单击editBtn，我可以将地址发送到 nextVC map .. 如果我在 nextVC继续我要去finalVC然后在这里我得到地址，在这里我需要在我单击editBtn的同一行中显示已编辑的地址..怎么做？

如下所示，我正在向 nextVC 发送地址：当我在 Tableview 中单击 editBtn 时，如下所示，我正在向 nextVC 发送地址（我想编辑）

func btnEditTapped(cell: EditAddressTableViewCell) {
    if let indexPath = self.addeditTableview.indexPath(for: cell){
        print("edit button address index \(indexPath.row)")
          let viewController = self.storyboard?.instantiateViewController(withIdentifier: "AddressViewController") as! AddressViewController
        viewController.isEdit = true
        var addrLo = addressArray[indexPath.row]

        print("in edit total mode address \(addrLo.pincode)")
        viewController.editPincode = addrLo.pincode
        viewController.editStree = addrLo.streetName
        viewController.editColony = addrLo.colony
        viewController.editCity = addrLo.city
        
    self.navigationController?.pushViewController(viewController, animated: true)
    }
} 

这是finalVC。 代码：在这里，如果我推送到 FirstViewController，那么应该用新地址编辑该行，但我在这里再添加一个 .. 编辑对我不起作用

 func editAddressService(){
   
let locations: [String: Any] = ["longitude": logitude as Any,"latitude": latitude as Any]

    let parameters: [String: Any] = [
                        "pincode": zipName,
                        "city": localityName,
                        "streetName": sublocalityName,
                        "colony": "",
                        "location" : locations,
                        "addressName" : addressTextfield.text
                    ]
        let string = "http://jcksdjfksdljfklsdl"

        var urlComponents = URLComponents(string: string)
        let saveAddrsID: String = addAddrsID ?? ""
    print("didload saved address userde edit service \(saveAddrsID)")

        let requestedUserType = URLQueryItem(name: "requestedUserType", value: "personal")

        let requestedItem = URLQueryItem(name: "addressType", value: "Other")

    let requestedItemAddr = URLQueryItem(name: "addressId", value: saveAddrsID)
    
    print("edit addressid \(requestedItemAddr)")

    let jsonData = try! JSONSerialization.data(withJSONObject: parameters, options: JSONSerialization.WritingOptions.prettyPrinted)
    let jsonString = NSString(data: jsonData, encoding: String.Encoding.utf8.rawValue)! as String
    print(jsonString)
    
        urlComponents?.queryItems = [requestedItem, requestedUserType, requestedItemAddr]
        let urlStr = urlComponents?.url

        let request = NSMutableURLRequest(url: urlStr!, cachePolicy: .useProtocolCachePolicy,timeoutInterval: 10.0)
        request.httpMethod = "POST"
        let postData = String(format: "addressdetails=%@",jsonString) .data(using: .utf8)
        request.httpBody = postData

        let session = URLSession.shared
        let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
            if error == nil {
                let httpResponse = response as? HTTPURLResponse
                if httpResponse!.statusCode == 200 {
                    do {
                        let jsonObject  = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String: Any]


                        self.editAddrsID = jsonObject["addressId"] as? String    
                        DispatchQueue.main.async {
                            let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FirstViewController") as! FirstViewController
                            
                            self.navigationController?.pushViewController(viewController, animated: true)
                        }
                        
                    } catch { print(error.localizedDescription) }
                } else {
                }
            }
        })
        dataTask.resume()
    }

要知道流程，我在 github 中仅添加了与此帖子相关的代码： https://github.com/SwiftSamples/AddressEdit

在我的 github 项目流程中将是： (profileVC showing all address from JSON) add/edit btn - > (addeditVC showing same profileVC address), editBtn - > profileAddressVC Map continueBtn - > ZoomMapVC(picked address need to show in edit btn index row in profile&addeditVC)

请帮助我编辑地址的代码。

用于编辑和添加：这是/saveaddress/ API 的区别

Answer 1

• 从 secondVC 保存 indexPath
• 将其传递给 finalVC
• 使用保存的 indexPath 在 finalVC 中获取单元格

secondVC 和 finalVC 中的排序和单元格数量当然必须相同
