形成这个数据，我正在获取数据array，但无法在tableview 上显示，而且我无法理解如何获取图像数组表单，这里的数据是我用于填充我的tableview 的代码
代码
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)
)
这里是我的模型类
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
我只是想说明为什么我的数据没有出现在 tableview 上，以及如何获取图像 array 并显示在 tableview 上，请帮助我
【问题讨论】：
要显示所有图片吗？ 是的，我想显示数组中的所有图像 请有人帮帮我 你能展示一下你的tableViewCell结构吗？ pelase 检查我已添加并筛选我的 tableview 单元格结构 【参考方案1】：在UITableViewCell 中添加UICollectionView 以显示所有图像。并使用您的图像数组填充UICollectionView。找到在UITableView Cell 中添加UICollectionView 的精彩教程
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]!
在你的循环中：
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)
)
【讨论】：
是的，但是如何从数据中获取图像数组 为模型中的图像定义一个数组。并在循环中在模型中投射数据时分配图像数组 请你说的更具体一些我无法理解 你能用数据填充tableView吗？？ 是的，我成功填充了该图像数组的问题【参考方案2】：Swift 4 发布后，Apple 推出了一种全新的 data encoding and decoding 协议方式，通过使您的自定义类型与一些易于采用的协议保持一致
1) 可编码 — 用于编码
2) 可解码 — 用于解码
3) Codable — 用于编码和解码
它还提供对类、结构和枚举的支持。
通过符合 Codable 协议，您必须将模型类创建为响应格式，无需手动解析数据。
在你的例子中：
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 响应函数中：
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，或者只需在网络上搜索该术语。
