Ios 如何使用字典数组解析JSON,ios,arrays,json,dictionary,swift4,Ios,Arrays,Json,Dictionary,Swift4,我有一个JSON数组，如下所示： func fetchProfessionalData() { guard let url = URL(string:"urlString") else { return } let parameters = ["Address":""] as [String : Any] Alamofire.request(url, method: .post, parameters:parameters,encoding: JSONEncodin

我有一个JSON数组，如下所示：

func fetchProfessionalData() {

    guard let url = URL(string:"urlString") else { return }

    let parameters = ["Address":""] as [String : Any]

    Alamofire.request(url, method: .post, parameters:parameters,encoding: JSONEncoding.default, headers: nil).responseJSON {
        response in
        switch response.result {
        case .success:      

            let jsonData = response.result.value as! NSArray

            print("response:\(jsonData)")
        }
            self.listTableView.reloadData()

            break
        case .failure(let error):

            print(error)
        }
    }
  }

这是我打印时得到的输出：

现在我有了一个tableViewCell，我必须在“lstServiceProviders”下显示“userName”、“profilePic”、“rating”、“email”和“serviceName”。到目前为止，我能够显示名称、图像、email和rating，但“lstServiceProviders”是另一个字典数组。我想在单元格中显示该服务提供商提供的所有服务

让我们在json第1条中说“用户名”：“jhonsmith”有“lstServicePrpviders”，其中包含两个带有“serviceName”的字典数组：第1条中的“BeautyCare”和第2条中的“serviceName”：“Carpentry”。我想在一个单元格中显示BeautyCare和Carpentry。如何做到这一点

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let listCell = tableView.dequeueReusableCell(withIdentifier: "listCell", for: indexPath) as! ListTableViewCell

    let string = "imageBaseUrl\(models![indexPath.row].profilePic!)"

    let escapedAddress = string.addingPercentEncoding(
        withAllowedCharacters: CharacterSet.urlQueryAllowed)

    listCell.listCellImage.image = UIImage(url: URL(string: escapedAddress!))
    listCell.listCellNamesLabel.text = models![indexPath.row].userName!
    let rating = models![indexPath.row].rating!
    listCell.listCellRating.text = "(\(rating)/5 & 5 Comments)"
    listCell.listCellStarRating.text = ratingArray[indexPath.row]

for i in 0..< models![indexPath.row].lstServiceProviders!.count {

       listCell.listCellServicesLbl.text =                      
              models![indexPath.row].lstServiceProviders[i].serviceName
    }
    return listCell
    }

override func tableView（tableView:UITableView，cellForRowAt indexath:indexPath）->UITableViewCell{
将listCell=tableView.dequeueReusableCell（标识符为：“listCell”，for:indexPath）设为！ListTableViewCell
让string=“imageBaseUrl\（模型！[indexath.row].profilePic！）”
让EscapeAddress=string.addingPercentEncoding(
withAllowedCharacters:CharacterSet.urlQueryAllowed）
listCell.listCellImage.image=UIImage（url:url（字符串：EscapeAddress！））
listCell.listCellNamesLabel.text=models！[indexath.row].userName！
让rating=models！[indexPath.row]。rating！
listCell.listCellRating.text=“（\（评级）/5和5评论）”
listCell.listcellstarting.text=ratingArray[indexPath.row]
对于0中的i..

[Swift 4]您可以使用带有可编码的模型来轻松管理tableviewcell
查看下面的代码并在操场上运行，您将了解我创建了易于循环和管理的模型对象：

如果响应是类似于输出的Json对象，请使用以下命令：

URLSession.shared.dataTask(with: gitUrl) { (data, response , error) in guard let data = data else { return } do { let decoder = JSONDecoder() let models = try decoder.decode([RootModel].self, from: data) } catch let err { print("Err", err) } }.resume()

在viewController中，声明varibale

var models: [RootModel]? { didSet { self.listTableView.reloadData() } }
在tableview委托方法中

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return models.count ?? 0 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { // Update your cell using models // cell.text = models[indexPath.row].userName }
[编辑2]添加所有字符串，然后显示值

var stringArray:[String] = [] for i in 0..< models![indexPath.row].lstServiceProviders!.count { stringArray.append( models![indexPath.row].lstServiceProviders[i].serviceName) } listCell.listCellServicesLbl.text = stringArray.joined(separator: ", ")

var stringArray:[String]=[] 对于0中的i..<模型！[indexath.row].lstServiceProviders！。计数{ stringArray.append（模型！[indexPath.row].lstServiceProviders[i].serviceName） } listCell.listCellServicesLbl.text=stringArray.joined（分隔符：“，”）
您可以使用AlamofireObject Mapper。@Mehul Sojitra我真的不知道这对我的案例有什么帮助，请花点时间深入学习。他们的文档中已经给出了所有内容。@Razib Mollick嘿，谢谢你的回复，我是一个初学者，正在努力学习如何使用它。我只是不理解我的json响应正确的
var json=“”[{…}]”“
。。那么，您的意思是我必须将json响应存储在
var json=response.result.value就是这样吗？不，您得到的响应与json数组或数据类似吗？请看编辑1。@Razib Mollick嘿，伙计，我已经编辑了我的问题，请看一次，然后告诉我怎么做。。提前感谢。@Razib Mollick嘿，Razib查看我的编辑我尝试了这种方式，但它显示了每个数组中最后的serviceName。不确定如何显示每个迭代的所有serviceName。@VenkateshChejarla，请参阅编辑2。或者告诉我您希望如何查看输出。别忘了接受我的回答。
