How to save user's input in variable using delegate? - ios

Question

I'm making ios app. Please look my table view image below.
If you click add(+) button, you can add ENG word and its meaning in Korean(KOR) in each textfield.
After filling the textfield and click save button (it is located on right-top, "저장"), the word is added like the image below.
word is added
For example, the ENG is endless and the meaning(KOR) is "끝없는".
And, I want to use UIReferenceLibraryViewController .
If i click the cell of the list, i want to show its dictionary.
#IBAction func viewDictionary(_ sender: UITapGestureRecognizer) {
let engDictionaryWord = **engListWord**
let ViewController = UIReferenceLibraryViewController(term: engDictionaryWord)
self.present(ViewController, animated: true, completion: nil)
}
I want to use this method.
But, I don't know how to save my ENG input in engListWord.
In pic2 's swift file(addWordViewController.swift), there is prepare() method like this.
// This method lets you configure a view controller before it's presented.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
super.prepare(for: segue, sender: sender)
// Configure the destination view controller only when the save button is pressed.
guard let button = sender as? UIBarButtonItem, button === saveButton else {
os_log("The save button was not pressed, cancelling", log: OSLog.default, type: .debug)
return
}
let eng = engTextField.text ?? ""
let kor = korTextField.text ?? ""
// Set the meal to be passed to WordTableViewController after the unwind segue.
word = Word(eng:eng, kor:kor)
}
and viewDidLoad() method in addWordViewController.swift
override func viewDidLoad() {
super.viewDidLoad()
engTextField.delegate = self
korTextField.delegate = self
// Set up views if editing an existing Word.
if let word = word{
engTextField.text = word.eng
korTextField.text = word.kor
}
// Do any additional setup after loading the view.
}
I don't know which variable i have to use.
There is other swift file in my project, If i misuploaded that codes above, please tell me! I will edit my question immediately.
Main.Storyboard
If i use GestureRecognizer, i made this code but I don't know it is right...
#IBAction func MyDictionary(_ sender: UITapGestureRecognizer) {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "viewDictionary", sender: indexPath)
}
func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// I just made this identifier up, but create one yourself in the storyboard
if segue.identifier == "viewDictionary" {
// Define your vc
let libController = segue.destination as! UIReferenceLibraryViewController
// Define indexPath
let indexPath = sender as! IndexPath
// Set value in destination vc
libController.engWord = words[indexPath.row].eng
}
}
}

I think the way to go is to use the UITableViewDelegate method didSelectRowAtindexPath in the WordTableViewController (if that's the class with your table view).
A gestureRecognizer does not seem like something you want in your tableViewController as it has nice build in delegate methods to register user presses. Therefore, replace your viewDictionary(_:) function with the following:
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "viewDictionary", sender: indexPath)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// I just made this identifier up, but create one yourself in the storyboard
if segue.identifier == "viewDictionary" {
// Define your vc
let libController = segue.destination as! UIReferenceLibraryViewController
// Define indexPath
let indexPath = sender as! IndexPath
// Set value in destination vc
libController.engWord = yourArrayOfEngWords[indexPath.row]
}
}
This will get your eng word of the cell you have pressed and save it to an attribute "engWord" that you then define in your UIReferenceLibraryViewController:
class UIReferenceLibraryViewController(){
var engWord: String = ""
// Rest your class properties and functions here...
}
Once it is set you can use it as you like after the segue has been performed :=)
