如何将图像数组从json格式解析为tabelview

从此数据中获取数据array，但无法显示在tableview上，并且我也无法理解如何获取图像数组，因为这里的数据是我填充{ {1}}
代码
tableview这里是我的模型课
func PreviousInspeList(){
let preferences = UserDefaults.standard
let uid = "u_id"
let acTkn = "acc_tkn"
let u_ID = preferences.object(forKey: uid)
let A_Token = preferences.object(forKey: acTkn)
let params = ["user_id": u_ID!, "access_token": A_Token!,"property_id": propertyID!]
print(params)
SVProgressHUD.show()
Alamofire.request(previousinspectionslist, method: .post, parameters: params).responseJSON(completionHandler: {(response) in
switch response.result{
case.success(let value):
let json = JSON(value)
print(json)
let data = json["data"]
data.array?.forEach({ (iList) in
let inspList = PreviousInspListModel(resolved: iList["resolved"].stringValue, type: iList["type"].stringValue, notes: iList["notes"].stringValue, property_id: iList["property_id"].stringValue, regulation_item: iList["regulation_item"].stringValue, locations: iList["locations"].stringValue, id: iList["id"].stringValue, boiler_service_date: iList["boiler_service_date"].stringValue, action: iList["action"].stringValue, intervention_required: iList["intervention_required"].stringValue, regulation_id: iList["regulation_id"].stringValue, regulation_item_name: iList["regulation_item_name"].stringValue, contravention: iList["contravention"].stringValue, contraventions_item_name: iList["contraventions_item_name"].stringValue)
self.preInspData.append(inspList)
})
self.tblListView.reloadData()
SVProgressHUD.dismiss()
case.failure(let error):
print(error.localizedDescription)
}
})
}
我只是想告诉我为什么我的数据没有在struct PreviousInspListModel {
var resolved: String
var type: String
var notes: String
var property_id: String
var regulation_item: String
var locations: String
var id: String
var boiler_service_date: String
var action: String
var intervention_required: String
var regulation_id: String
var regulation_item_name: String
var contravention: String
var contraventions_item_name: String
}
上填充，以及如何获取图像tableview并在array上显示，请对此提供帮助

在UICollectionView内添加UITableViewCell以显示所有图像。并使用您的图片数组填充UICollectionView。找到在UICollectionView单元格内添加UITableView的绝佳教程
https://ashfurrow.com/blog/putting-a-uicollectionview-in-a-uitableviewcell-in-swift/
struct PreviousInspListModel {
var resolved: String
var type: String
var notes: String
var property_id: String
var regulation_item: String
var locations: String
var id: String
var boiler_service_date: String
var action: String
var intervention_required: String
var regulation_id: String
var regulation_item_name: String
var contravention: String
var contraventions_item_name: String
var imageArray: [String]!
}
在您的循环中：
data.array?.forEach({ (iList) in
let inspList = PreviousInspListModel(resolved: iList["resolved"].stringValue, type: iList["type"].stringValue, notes: iList["notes"].stringValue, property_id: iList["property_id"].stringValue, regulation_item: iList["regulation_item"].stringValue, locations: iList["locations"].stringValue, id: iList["id"].stringValue, boiler_service_date: iList["boiler_service_date"].stringValue, action: iList["action"].stringValue, intervention_required: iList["intervention_required"].stringValue, regulation_id: iList["regulation_id"].stringValue, regulation_item_name: iList["regulation_item_name"].stringValue, contravention: iList["contravention"].stringValue, contraventions_item_name: iList["contraventions_item_name"].stringValue, imageArray: iList["images"].arrayObject as? [String])
self.preInspData.append(inspList)
})

在Swift 4发行版中，Apple通过使您的自定义类型与一些易于采用的协议保持一致，从而推出了data encoding and decoding协议的全新方式
1）可编码—用于编码
2）可解码—用于解码
3）Codable －同时用于编码和解码
它还提供对类，结构和枚举的支持。
通过遵循Codable协议，您必须将模型类创建为响应格式，而无需手动解析数据。
在您的示例中：
struct ResponseData : Codable {
let message: String
let data : [PreviousInspListModel]
}
struct PreviousInspListModel : Codable {
let resolved: String?
let notes : String
let type: String
let images: [String]
}
在您的Api响应功能中：
Alamofire.request(previousinspectionslist, method: .post, parameters: params, encoding: JSONEncoding.default, headers: nil).responseData { (responseData) in
responseData.result.ifSuccess {
if let data = responseData.data{
do {
let response = try JSONDecoder().decode(ResponseData.self, from: data) //Decode JSON Response Data
print(response)
} catch let parsingError {
print("Error", parsingError)
}
}
}
}
您可以找到有关swift 4 codable的更多详细信息，或者只是在网上搜索该词。
