как разобрать массив изображений из формата json в tabelview

Question

привет, у меня есть данные json, как показано ниже

}

из этих данных я получаю данные array, но не могу отобразить наtableview а также я не могу понять, как получить массив изображений из этих данных. Вот мой код для заполнения моего tableview

Код

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)
        }

    })
}

вот мой класс модели

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
}

Я просто хочу сказать, почему мои данные не заполняются на tableview и как получить изображения array, а также отображаться на tableview, пожалуйста, помогите мне в этом

Answer 1

Swift 4, Apple представила совершенно новый способ кодирования и декодирования данных протоколов, сопоставляя ваши пользовательские типы с некоторыми простыми в использовании протоколами

1) Кодируемые - для кодирования

2) Декодируемый - для декодирования

3) Кодируемый - как для кодирования, так и для декодирования

Он также поддерживает класс, структуру и перечисление.

В соответствии с протоколом Codable вы должны создать класс модели в качестве формата ответа, не нужно анализировать данные вручную.

В вашем примере:

struct ResponseData : Codable {
    let message: String
    let data : [PreviousInspListModel]
}

struct PreviousInspListModel : Codable {
    let resolved: String?
    let notes : String
    let type: String
    let images: [String]
}

В вашемФункция ответа API:

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)
                    }
                }
            }
        }

Вы можете найти более подробную информацию о swift 4 codable или просто выполнить поиск по термину в Интернете.

Answer 2

Добавьте UICollectionView внутри UITableViewCell, чтобы показать все изображения.и используйте массив изображений для заполнения UICollectionView.найдите отличный учебник для добавления UICollectionView внутри UITableView ячейки

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]!
}

в вашем цикле:

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)
            })
