Swift: How to access value of selected table view cells - ios

Question

How can I access the value of the cell of the table view that the user selects? I know how to access the value if the user hasn't searched because I can just access the IndexPath's value of my array, but I can't when the user has searched something because the townArray won't line up with the cells that are shown.
To give you a better understanding- just say I have an array of fruits which has [apples, bananas, oranges]. If the user searches for bananas, then the only cell with text showing (results) will say bananas. If I then try to access the IndexPath element of fruits, I will get apples since it is the first element of fruits and bananas is the first element showing. What I want is to get the access the value bananas when the user selects bananas and searches "bananas" instead of apples. I know this may be confusing but please let me know if you have any thoughts on how I can solve this issue.

Answer 1

var searchedResult: [Fruit] = yourSearchingFunction()
tableview.reloadData()
IndexPaths would refresh correctly after TableView reloaded with a new collection of fruits
Explanation is showed with the following code:
class ViewController: UIViewController {
#IBOutlet private weak var tableView: UITableView!
private var originalFruits: [Fruit] = [] // This data is used to cache
private var fruits: [Fruit] = [] // This data is used to display on TableView
// MARK: - View Cycle
override func viewDidLoad() {
super.viewDidLoad()
setupTableView()
setupData()
}
private func setupData() {
// Loading all fruits at the first time [Apple, Banana, Orange ]
originalFruits = yourSetupDataFunctionToFetchAllFruitsAtTheFirstTime()
fruits = originalFruits
tableView.reloadData()
}
#IBAction private func actionTapToSearchButton(_ sender: Any) {
let searchingKey = searchTextField.text
if searchingKey.isEmpty {
fruits = originalFruits
} else {
fruits = yourSeacrchingFruitFunction(searchingKey)
}
tableView.reloadData()
}
}
// MARK: - UITableViewDataSource
extension ViewController: UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return fruits.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = tableView.dequeueReusableCell(withIdentifier: FruitCell.identifier) as? FruitCell {
return cell
}
return UITableViewCell()
}
}
// MARK: - UITableViewDelegate
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
}
}
