Alamofire和Objectmapper将数据添加到tableview

本文介绍了Alamofire和Objectmapper将数据添加到tableview的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 [ { "userId": 1, "id": 1, "title": "xxxxx", "body": "yyyyy" }, {

我的json数据是这样的，我正在使用alamofire加载数据和objectmapper进行映射。

My json data is like that and I'm using alamofire for loading data and objectmapper for mapping.

我创建一个swift文件进行映射：

I create a swift file for mapping like that:

import Foundation import ObjectMapper class TrainSchedules: Mappable { var mySchedules: [Schedules] required init?(map: Map) { mySchedules = [] } func mapping(map: Map) { mySchedules <- map["schedule"] } } class Schedules: Mappable { var userId: String var id: String var title: String var body: String required init?(map: Map) { userId = "" id = "" title = "" body = "" } func mapping(map: Map) { userId <- map["userId"] id <- map["id"] title <- map["title"] body <- map["body"] } }

和我的视图控制器一样：

and my view controller like that:

import Alamofire import ObjectMapper class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = UITableViewCell() cell.textLabel?.text = "Landmark" return cell } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 10 } @IBOutlet weak var tableViewData: UITableView! override func viewDidLoad() { super.viewDidLoad() tableViewData.dataSource = self tableViewData.delegate = self let jsonDataUrl = "jsonplaceholder.typicode/posts" Alamofire.request(jsonDataUrl).responseJSON { response in print("Request: \(String(describing: response.request))") print("Response: \(String(describing: response.response))") print("Result: \(response.result)") if let json = response.result.value { print("JSON: \(json)") } if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) { print("Data: \(utf8Text)") } } } }

I试图将json数据打印到TableView.Data即将到来，但我不能dd it to tableview。我该怎么做才能解决这个问题？

I tried to print json data to TableView.Data is coming however I couldn't add it to tableview.What should I do to solve this problem ?

推荐答案

你不需要TrainSchedules模型。

You don't need TrainSchedules model.

您的型号：

import Foundation import ObjectMapper class Schedule: Mappable { var userId: String var id: String var title: String var body: String required init?(map: Map) { userId = "" id = "" title = "" body = "" } func mapping(map: Map) { userId <- map["userId"] id <- map["id"] title <- map["title"] body <- map["body"] } }

你的ViewController：

Your ViewController:

import Alamofire import ObjectMapper import UIKit class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { @IBOutlet weak var tableViewData: UITableView! var schedules: [Schedule]? override func viewDidLoad() { super.viewDidLoad() tableViewData.dataSource = self tableViewData.delegate = self loadData() } func loadData() { let jsonDataUrl = "jsonplaceholder.typicode/posts" Alamofire.request(jsonDataUrl).responseJSON { response in self.schedules = Mapper<Schedule>().mapArray(JSONObject: response.result.value) self.tableViewData.reloadData() } } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = UITableViewCell() cell.textLabel?.text = schedules?[indexPath.row].title return cell } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return schedules?.count ?? 0 } }
