How to order cells based on quiz results? - ios

Question

I've built a likert quiz and I'm trying to create a results page that looks like the second view controller. So far all I've been able to return is the score and personality ranked (first view controller).
I'm not sure how I can show the quiz results in order. I basically would want to rank them and adjust the cells, while showing the point total but I have no clue what to do.
class SurveyResultsViewController: UITableViewController {
#IBOutlet var lblSortedScores : [UILabel]!
#IBOutlet var sortedTitle : [UILabel]!
#IBOutlet weak var cellFinishButton : UITableViewCell!
var survey: LikertSurvey?
var points = [0, 0, 0, 0]
var results: [(Int, Int)] = []
override func viewDidLoad() {
super.viewDidLoad()
UserDefaults.standard.setValue(points, forKey: "points")
self.setResults()
self.initUI()
}
private func setResults() {
for (index, point) in points.enumerated() {
results.append((index, point))
}
results.sort { (result1, result2) -> Bool in
return result1.1 > result2.1
}
}
private func initUI() {
for i in 0 ..< results.count {
let title = survey!.questionCategories[results[i].0]
lblSortedScores[i].text = "\(title) = \(results[i].1) points"
sortedTitle[i].text = "\(title)"
}
let finishButtonTap = UITapGestureRecognizer(target: self, action: #selector(self.finishButtonTapped(_:)))
cellFinishButton.addGestureRecognizer(finishButtonTap)
self.navigationItem.hidesBackButton = false
}
#objc func finishButtonTapped(_ sender: UITapGestureRecognizer) {
self.survey?.completed = true
let alertController = UIAlertController(title: "Congratulations! You earned 100 XP from completing this quest!", message: "", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "Ok",
style: .default) { action in
self.performSegue(withIdentifier: "unwindToSectionTableView", sender: self)
})
self.present(alertController, animated: true, completion: nil)
}
}

Try restructuring your code like so
var results: [(index: Int, points: Int)] = []
...
private func setResults() {
for (index, point) in points.enumerated() {
results.append((index, point))
}
results.sort{ $0.points > $1.points }
self.initUI()
}
