【中文标题】如何显示来自 Api 和 Json.file 的数据【英文标题】：How to Display Data From Api and Json.file 【发布时间】：2018-09-28 06:42:30 【问题描述】：我有两个数据 1.来自json 2.来自json.file
数据格式如下：-
"data": [
"question": "Gender",
"options": [
"Male",
"Female"
],
"button_type": "2"
,
"question": "How old are you",
"options": [
"Under 18",
"Age 18 to 24",
"Age 25 to 40",
"Age 41 to 60",
"Above 60"
],
"button_type": "2"
,
"button_type": "2",
"question": "I am filling the Questionnaire for?",
"options": [
"Myself",
"Mychild",
"Partner",
"Others"
]
]
这是我的模型：-
enum NHAnswerType:Int
case NHAnswerCheckboxButton = 1
case NHAnswerRadioButton
case NHAnswerSmileyButton
case NHAnswerStarRatingButton
case NHAnswerTextButton
class NH_QuestionListModel: NSObject
var dataListArray33:[NH_OptionsModel] = []
var id:Int!
var question:String!
var buttontype:String!
var options:[String]?
var v:String?
var answerType:NHAnswerType?
var optionsModelArray:[NH_OptionsModel] = []
init(dictionary :JSONDictionary)
guard let question = dictionary["question"] as? String,
let typebutton = dictionary["button_type"] as? String,
let id = dictionary["id"] as? Int
else
return
// (myString as NSString).integerValue
self.answerType = NHAnswerType(rawValue: Int(typebutton)!)
if let options = dictionary["options"] as? [String]
print(options)
for values in options
print(values)
let optionmodel = NH_OptionsModel(values: values)
self.optionsModelArray.append(optionmodel)
self.buttontype = typebutton
self.question = question
self.id = id
选项模型：-
class NH_OptionsModel: NSObject
var isSelected:Bool? = false
var textIndexPath :IndexPath?
var dummyisSelected:Bool? = false
var v:String?
var values:String?
init(values:String)
self.values = values
print( self.values)
questionviewmodel:-中的视图模型-
func loadData(completion :@escaping (_ isSucess:Bool) -> ())
loadFromWebserviceData (newDataSourceModel) in
if(newDataSourceModel != nil)
self.datasourceModel = newDataSourceModel!
completion(true)
else
completion(false)
func loadFromWebserviceData(completion :@escaping (NH_QuestionDataSourceModel?) -> ())
//with using Alamofire ..............
// http://localhost/json_data/vendorlist.php
Alamofire.request("http://www.example.com").validate(statusCode: 200..<300).validate(contentType: ["application/json"]).responseJSON response in
let status = response.response?.statusCode
print("STATUS \(status)")
print(response)
switch response.result
case .success(let data):
print("success",data)
let result = response.result
print(result)
if let wholedata = result.value as? [String:Any]
print(wholedata)
// let data2 = wholedata["data"] as? [String:Any]
self.datasection1 = wholedata
if let data1 = wholedata["data"] as? Array<[String:Any]>
print(data)
print(response)
for question in data1
let typebutton = question["button_type"] as? String
print(typebutton)
self.type = typebutton
let options = question["options"] as! [String]
// self.dataListArray1 = [options]
self.tableArray.append(options)
// self.savedataforoptions(completion: <#T##(NH_OptionslistDataSourceModel?) -> ()#>)
self.no = options.count
print(self.tableArray)
let newDataSource:NH_QuestionDataSourceModel = NH_QuestionDataSourceModel(array: data1)
completion(newDataSource)
case .failure(let encodingError ):
print(encodingError)
// if response.response?.statusCode == 404
print(encodingError.localizedDescription)
completion(nil)
虚拟数据视图模型：-
func loadFromDummyData(completion :@escaping (NH_DummyDataSourceModel?) -> ())
if let path = Bundle.main.path(forResource: "jsonData", ofType: "json")
do
let jsonData = try NSData(contentsOfFile: path, options: NSData.ReadingOptions.mappedIfSafe)
do
let jsonResult: NSDictionary = try JSONSerialization.jsonObject(with: jsonData as Data, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
// self.datasection2 = jsonResult as! [String : Any]
let people1 = jsonResult["data"] as? [String:Any]
self.datasection2 = jsonResult as! [String : Any]
if let people = jsonResult["data"] as? Array<[String:Any]>
// self.dict = people
for person in people
let options = person["options"] as! [String]
self.tableArray.append(options)
let name = person ["question"] as! String
self.tableArray.append(options)
let newDataSource:NH_DummyDataSourceModel = NH_DummyDataSourceModel(array: people)
completion(newDataSource)
catch
catch
func loadData1(completion :@escaping (_ isSucess:Bool) -> ())
loadFromDummyData (newDataSourceModel) in
if(newDataSourceModel != nil)
self.datasourceModel = newDataSourceModel!
completion(true)
else
completion(false)
终于在viewcontroller:-
在viewDidLoad:-
questionViewModel.loadData (isSuccess) in
if(isSuccess == true)
let sec = self.questionViewModel.numberOfSections()
for _ in 0..<sec
self.questionViewModel.answers1.add("")
self.questionViewModel.questions1.add("")
self.questionViewModel.questionlist1.add("")
self.item1 = [self.questionViewModel.datasection1]
self.activityindicator.stopAnimating()
self.activityindicator.isHidden = true
self.tableview.refreshControl = refreshControl
self.tableview .allowsMultipleSelection = false
self.tableview.reloadData()
self.dummyDataViewModel.loadData1 (isSuccess) in
if(isSuccess == true)
else
self.viewDidLoad()
else
self.activityindicator.stopAnimating()
self.activityindicator.isHidden = true
let controller = UIAlertController(title: "No Internet Detected", message: "This app requires an Internet connection", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default)
UIAlertAction in
NSLog("OK Pressed")
self.viewDidLoad()
controller.addAction(okAction)
self.present(controller, animated: true, completion: nil)
self.sections = [Category(name:"A",items:self.item1),
Category(name:"B",items:self.item2),
]
print(self.sections)
self.tableview.reloadData()
这是来自 json.file 和 api 的格式。 我用过tableview。
所以我需要从关键“问题”中列出标题标题
并且应该从选项键显示行的单元格。
那么如何将Json和Json.file这两个数据相加呢？
【问题讨论】：
您是否尝试过任何方法来实现这一目标？显示你的代码？ 请转到 app.quicktype.io 并粘贴您的 JSON。它为您创建数据模型以使用Decodable 解码 JSON
...不要repost questions
【参考方案1】：
您可以创建代表您的模型的模型。最好喜欢
struct ResponseModel: Codable
var data: [Question]?
struct QuestionModel
var question: String?
var options: [String]?
然后在你的 Ajax post 使用之后
let responseData = try JSONDecoder().decode(AjaxResponse<ResponseModel>.self, from: data!)
现在你有你的数据了。
然后你可以在你的 UITableViewDeleates 中做
//节数
resposnseData.data.count
//节的行数
responseData.data[section].options.count
//用于索引的单元格修改您的单元格使用
response.data[indexPath.section].options[indexPath.row]
希望对你有帮助。
【讨论】：
如果 JSON 显然总是包含所有键，请不要建议可选类型。 @vadian 是的。这只是一个快速的答案。可能我会添加评论 @vinbhai4u 我已经更新了我的代码。请检查一下。如何组合这两个数据以及如何在 tableview 中列出数据？以上是关于如何显示来自 Api 和 Json.file 的数据的主要内容，如果未能解决你的问题，请参考以下文章
