Getting Values from UISliders alongside UserID (linking User to section number?) - swift3

Question

I'm working on creating a 'Rate' feature in my app where it pulls the users to rate from an external API. I then create a TableView which adds cells that contain a section name (the name of the User) and a UISlider.
What I'm trying to do is gather the data from the UISliders along with the User ID associated with the User who's section it is so that I can call a POST action to the API to send the rating data too.
Here's the code I have: (For the record, first time with Swift, the comments are me trying to figure out how to do this). Any ideas?
import UIKit
import Alamofire
class RateViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var submitButton: UIButton!
#IBOutlet weak var activeSurveyLabel: UILabel!
private var myTableView: UITableView!
var usersToRate = [User]()
var activeSurveyId: String?
var rateData = [String: Int]()
var sectionIdToUserId = [Int: String]()
var userIdSection = [Int: String]()
override func viewDidLoad() {
super.viewDidLoad()
submitButton.isHidden = true
submitButton.addTarget(self, action: #selector(pressSubmitButton(button:)), for: UIControlEvents.touchUpInside)
activeSurveyLabel.isHidden = false
self.loadUsersToRate()
Alamofire.request(RateRouter.getSurvey()).responseJSON { response in
debugPrint(response)
if let string = response.result.value as? [[String: Any]]{
if string.count == 0 {
return
}
self.submitButton.isHidden = false
self.activeSurveyLabel.isHidden = true
for survey in string {
if let survey = Survey(json: survey) {
self.activeSurveyId = survey._id!
print(survey._id!)
}
}
//if there's a result, show slider bars for each person on the team with rating scales (except for the person logged in)
//have a submit button with a post request for the votes
let barHeight: CGFloat = UIApplication.shared.statusBarFrame.size.height
let displayWidth: CGFloat = self.view.frame.width
let displayHeight: CGFloat = barHeight * CGFloat(self.usersToRate.count * 5)
self.myTableView = UITableView(frame: CGRect(x: 0, y: barHeight, width: displayWidth, height: displayHeight - barHeight))
self.myTableView.register(UITableViewCell.self, forCellReuseIdentifier: "MyCell")
self.myTableView.dataSource = self
self.myTableView.delegate = self
self.view.addSubview(self.myTableView)
} else {
print(response.result.error!)
let label = UILabel()
label.center = self.view.center
label.text = "No Active Surveys"
self.view.addSubview(label)
}
}
// Do any additional setup after loading the view.
}
func loadUsersToRate() {
Alamofire.request(RateRouter.getUsers()).responseJSON { response in
guard let jsonArray = response.result.value as? [[String: Any]] else {
print("didn't get array, yo")
return
}
for item in jsonArray {
if let user = User(json: item) {
self.usersToRate.append(user)
self.rateData.updateValue(5, forKey: user.userId!) //initialize user average data at 5 in case they don't change it
print (self.rateData)
}
}
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Num: \(indexPath.row)")
print("Value: \(usersToRate[indexPath.row])")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
self.sectionIdToUserId.updateValue(usersToRate[section].userId!, forKey: section)
print(self.sectionIdToUserId)
return "\(usersToRate[section].name!)"
}
func numberOfSections(in tableView: UITableView) -> Int {
return usersToRate.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath as IndexPath)
let slider = UISlider(frame: CGRect(x: 0, y:0, width: 400, height: 44))
slider.isUserInteractionEnabled = true
slider.minimumValue = 1
slider.maximumValue = 10
slider.value = 5
slider.tag = indexPath.section
slider.addTarget(self, action: #selector(sliderValueChange(sender:)), for: UIControlEvents.valueChanged)
cell.addSubview(slider)
return cell
}
func sliderValueChange(sender: UISlider) {
//get slider value
var currentValue = Int(sender.value)
print(currentValue)
//self.rateData.updateValue(currentValue, forKey: self.sectionIdToUserId.values[sender.])
//get user id for that value
//self.rateData.updateValue(currentValue, rateData[section])
// self.rateData.updateValue(currentValue, forKey: 0)
}
func pressSubmitButton(button: UIButton) {
for user in usersToRate {
// Alamofire.request(RateRouter.vote(voteFor: user.userId!, survey: activeSurveyId, rating:))
}

Answer 1

To answer my own question, what I did was create a different model called 'Votes' that stored the information for each vote.
Then to fill that array I created a tag for the slider in the tableView based on the section ID and used that to update the current value.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath as IndexPath)
let slider = UISlider(frame: CGRect(x: 0, y:0, width: cell.frame.width , height: 44))
slider.tag = indexPath.section
slider.addTarget(self, action: #selector(sliderValueChange(sender:)), for: UIControlEvents.valueChanged)
cell.addSubview(slider)
return cell
}
func sliderValueChange(sender: UISlider) {
//get slider value
var currentValue = Int(sender.value)
print(currentValue)
voteData[sender.tag].rating = currentValue
}
