在我从 api 进行 http 调用后，我得到了 json 文件，然后我循环通过它来获取特定的值：

   if let value: AnyObject = response.result.value as AnyObject? {
        let json = JSON(value)    
       for (key, subJson) in json {   
           let drivers = subJson["driver"]
           for (key, subJson) in drivers {

              let status = subJson["status"].stringValue
              let date = subJson["created_at"].stringValue
              let name = subJson["name"].stringValue    
              let pivot = subJson["pivot"]
               for (key, subJson) in subJson["pivot"] {
                    let type = pivot["type"].stringValue


                             let data = Driverj(name: name, status: status, created_at: date)


                            self.data.append(data)

                        }


                        DispatchQueue.main.async {
                            self.tableview.reloadData()
                        }
                       }
                     }
            }

在一个单独的文件中，我将值与对象连接起来：

class DriverC: UITableViewCell  {

@IBOutlet weak var status : UILabel!
@IBOutlet weak var date : UILabel!
@IBOutlet weak var job : UILabel!
@IBOutlet weak var update : UILabel!
  }

在另一个文件中，我保存了数据：

 import Foundation
 import ObjectMapper

  class Driverj : Mappable {


var status : String?
var name : String?
var created_at : String?

required init?(map: Map) {
}
required init(name: String , status : String , created_at : String )  {
    self.status = status
    self.name = name
    self.created_at = created_at



}
func mapping(map: Map) {

    status      <- map["status"]
    name             <- map["name"]
    created_at            <- map["created_at"]
}

}

最后是它的显示方式

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

    let cell = tableView.dequeueReusableCell(withIdentifier: "DriverCell", for: indexPath) as! DriverC

    let entry = data[indexPath.row]


    cell.date.text = entry.date
    cell.job.text = entry.job
    cell.status.text = entry.status
    cell.update.text = entry.name
    return cell


}

我的问题是当我运行我的项目时，我会得到三个重复相同数据的单元格。为什么 ？

json文件：
