我想將填充按鈕（●）的值保存到關于每個問題“q.question[indexPath.row]”的陣列“q.answer[indexPath.row]”中。當前每次當?更改為●時都會更新currentQuizButtonIndex通過點擊。但是，我不知道如何保存到在 TableViewController 中宣告的變數 q 中。 視圖控制器顯示
關于 QuizCell.swift 的代碼（TableCell 大約有 5 個按鈕和 UIlabel。）
import UIKit
import Foundation
protocol QuizCellDelegate {
func quizCellDidChangeCurrentButtonIndex(_ cell: QuizCell, index: Int)
}
class QuizCell: UITableViewCell {
var currentQuizButtonIndex: Int = 0 {
didSet {
let value = self.currentQuizButtonIndex
self.updateCurrentQuizButton(value)
if let delegate = self.delegate {
delegate.quizCellDidChangeCurrentButtonIndex(self, index: value)
}
}
}
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet var answerButtons: [UIButton]!
var delegate: QuizCellDelegate?
override func awakeFromNib() {
super.awakeFromNib()
//print("ここまできてるか確認")
// Initialization code
}
@IBAction func didTapQuizButton(_ sender: UIButton) {
if let index = self.answerButtons.firstIndex(of: sender){
self.currentQuizButtonIndex = index
delegate?.quizCellDidChangeCurrentButtonIndex(self, index: index)
print(index)
}
}
private func updateCurrentQuizButton(_ currentIndex: Int){
for (index, answerButton) in self.answerButtons.enumerated(){
if index == currentIndex {
answerButton.setTitle("●", for: .normal)
} else {
answerButton.setTitle("○", for: .normal)
}
}
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
視圖控制器代碼
import UIKit
class AnswerQuizViewController: UIViewController, UITableViewDelegate {
var q: QuestionSeries!
@IBOutlet weak var quizTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
quizTableView.dataSource = self
quizTableView.delegate = self
// cell xibファイルを使うときは書く必要があるやつ。
// quizTableView.register(UINib(nibName: K.Cells.QuizCellNibName, bundle: nil), forCellReuseIdentifier: K.Cells.QuizCellIdentifier)
quizTableView.register(UINib(nibName: "QuizCell", bundle: nil), forCellReuseIdentifier: "QuizCellIdentifier")
// Do any additional setup after loading the view.
}
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
// override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// // Get the new view controller using segue.destination.
// // Pass the selected object to the new view controller.
//// if segue.identifier == K.Segue.checkResult {
//// let resultViewController = segue.destination as! ResultViewController
//// answerQuizViewController.q =
//// print(answerQuizViewController.q)
// }
}
// MARK: - quizTableViewのアレンジ
extension AnswerQuizViewController: UITableViewDataSource, QuizCellDelegate {
func quizCellDidChangeCurrentButtonIndex(_ cell: QuizCell, index: Int) {
if let indexPath = self.quizTableView.indexPath(for: cell){
self.q.question[indexPath.row].answer = index
print(index)
}else{
print("ここきてます")
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return q.question.count
//print(q.question.count)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let question = q.question[indexPath.row]
let cell = quizTableView.dequeueReusableCell(withIdentifier: K.Cells.QuizCellIdentifier, for: indexPath) as! QuizCell
cell.questionLabel.text = question.text
// print(question.text)
return cell
}
}
如果您有任何想法以其他方式實作這一點，這也很有幫助。謝謝。

如何創建一個靜態陣列并將資料存盤到該陣列中。當按鈕被點擊時，您可以將其附加到該靜態陣列中。
創建一個新檔案。只是一個基本的“Swift 檔案”。
struct structName {
static var qArray: [String] = []
}
然后通過以下方式附加資料：
structName.q.append()
最后讓你的資料槽：
structName.q[index]
