Swift3：如何在UITableViewCell中保存UITextView数据

Question

How do you save a UITextView data in a UITableViewCell respectively? I have two files, one is TableViewController and descViewController . In TableViewController , an array of words are stored and each cell is connected to descViewController , where a UITextView is set. I want to save the text data in each cell. How am I able to do it? The following is my attempt which almost succeeded

- In my descViewController;

@IBOutlet weak var myLabel: UILabel!
var passedValue = ""
var passedText = ""
@IBOutlet weak var myTextView: UITextView!

In viewDidLoad Inside descViewController

myTextView.delegate = self
myTextView.text = passedText
myTextView.font = UIFont(name: "times new roman", size: 15)
myLabel.text = passedValue

- In my TableViewController;

  func textData() -> String {

    if let txt = textViewUserDefaults.object(forKey: "txtData") as? String {
       return txt
    }
    return ""
}

  override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    // Get Cell Label
    let indexPath = tableView.indexPathForSelectedRow;
    let currentCell = tableView.cellForRow(at: indexPath!) as UITableViewCell!;
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let viewController = storyboard.instantiateViewController(withIdentifier: "desc") as! descViewController

    viewController.passedValue = (currentCell?.textLabel?.text)!
    viewController.passedText = textData()
    let navController = UINavigationController(rootViewController: viewController)
    self.present(navController, animated: false , completion: nil)
}

I have created this method. The destination when each cell is clicked is descViewController where I prepared passedText and passedValue . This passedValue is a UIlable . This lable is for a String to be displayed in descViewController This result is successful. However, although my text view data is passed successfully, every cell data is going to hold the same value. For example, if I write something like "Today is a sunny day!", save it, and when I click another cell to open descViewController , the result is "Today is a sunny day!" in my text view. This is trouble I have right now. Code I wrote for storing data is in the following; textViewUserDefaults is a name I set by using UserDefaults.Standard .

textViewUserDefaults.set(self.myTextView.text, forKey: "txtData")

I want to have each cell hold each value. Could you provide me with code that works successfully?

Thank you

 let YOURARRAYNAME : NSMutableArray = NSMutableArray()

When user enter some text and submit it then add that text in your array

YOURARRAYNAME.addObject(YOURTEXT)

In this method

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

You got tableview cell index path so when you want to pass a data

let viewController = storyboard.instantiateViewController(withIdentifier: "desc") as! descViewController

viewController.passedValue = YOURARRAYNAME.objectAtIndex(indexpath.row) // here you pass text and what is passedvalue i dont know so you check this
viewController.passedText = textData() // what is your passedtext and textdata() you also pass value here 
let navController = UINavigationController(rootViewController: viewController)
self.present(navController, animated: false , completion: nil)
