How to Display Data From Api and Json.file - ios

Question

I have two data's
1. From json
2. From json.file
Tha data format is below:-
{
"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"
]
}
]
}
This is my model:-
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)
}
}
Viewmodel in questionviewmodel:-
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)
}
}}
dummy data viewmodel:-
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)
}
}
}
finally in the viewcontroller:-
in 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()
}
This is the format from json.file and also from the api.
I have used tableview.
So i need to list the header title from the key "question"
And the cell for row should display from the option keys.
So how to add this two data from the Json and Json.file?

Answer 1

You can create your models which represents your model. Preferably like
struct ResponseModel: Codable {
var data: [Question]?
}
struct QuestionModel{
var question: String?
var options: [String]?
}
Then after your Ajax post use
let responseData = try JSONDecoder().decode(AjaxResponse<ResponseModel>.self, from: data!)
Now you have your data.
You can then do in your UITableViewDeleates
//number of sections
resposnseData.data.count
//number of rows in section
responseData.data[section].options.count
//cell for index modify your cell using
response.data[indexPath.section].options[indexPath.row]
Hope it helps.
