我有两个数据 1.从json 2.从json.file
Tha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"
]
}
]
}
这是我的模特：-
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
}
}
optionmodel：-
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)
}
}
}
最后在viewcontroller中：-
在viewDidLoad中：-
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“问题”键中列出标题标题
该行的单元格应通过选项键显示。
那么如何从Json和Json.file添加这两个数据？
答案 0 :(得分：0)
您可以创建代表您的模型的模型。最好像
struct ResponseModel: Codable {
var data: [Question]?
}
struct QuestionModel{
var question: String?
var options: [String]?
}
然后在使用Ajax后
let responseData = try JSONDecoder().decode(AjaxResponse<ResponseModel>.self, from: data!)
现在您有了数据。
然后您可以在UITableViewDeleates中完成
//节数
resposnseData.data.count
//节中的行数
responseData.data[section].options.count
//用于索引的单元格使用
response.data[indexPath.section].options[indexPath.row]
希望有帮助。
