Get textLabel from UITableView - swift

Question

I need to get textLabel from row in UITableView. But I get nil. I need to get textLabel, because I'm using UISearchBar, if I will try to get data using index, when searching, I will receive incorrect indexes. So , I want to get textLabel.
Please, fix where I'm wrong
When I am typing in searchBar items in TableView change. But index doesn't. For example Food = ["Apple", "Banana", "Coca-Cola"]. If I use searchBar and enter "Banana". Then I click on this , but I get Apple (because this is index - 0). That's why I want to get textLabel
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//let meal = foods[indexPath.item]
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let labelContent = cell.textLabel!.text
print(labelContent)
}
UISearchBar
extension FoodViewController: UISearchBarDelegate {
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
searchedFoods = foods.filter({ $0.title.lowercased().prefix(searchText.count) == searchText.lowercased() })
searching = true
tableView.reloadData()
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searching = false
searchBar.text = ""
tableView.reloadData()
}
}

Answer 1

Never get data from the view, the cell, get it always from the model, the data source.
And never use dequeueReusableCell outside of cellForRowAt. You won't get the cell you expect.
In this case you have to get the data depending on searching
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let labelContent : String
if searching {
labelContent = searchedFoods[indexPath.row].title
} else {
labelContent = foods[indexPath.row].title
}
print(labelContent)
}
And your filter method is horrible. Change it to much more efficient
searchedFoods = foods.filter { $0.title.range(of: searchText, options: [.caseInsensitive, .anchored] != nil) }
Finally I recommend to change textDidChange to cancel searching also if the search text becomes empty and remove the unused items from searchedFoods.
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchText.isEmpty {
searchedFoods.removeAll()
searching = false
} else {
searchedFoods = foods.filter{ $0.title.range(of: searchText, options: [.caseInsensitive, .anchored]) != nil }
searching = true
}
tableView.reloadData()
}

Answer 2

As I have figured out the problem is that you are using indexPath.item that's why you are getting the wrong index please try this
let meal = foods[indexPath.row]

Answer 3

If you want to get a text from the UILabel on tap of cell
confirm UITableViewDelegate
//Access the array that you have used to fill the tableViewCell
print(foods[indexPath.row]) it will print selected row
OR
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! UITableViewCell
let labelContent = cell.textLabel!.text
print(labelContent)
}

Answer 4

Lets just say instead of getting data from foods (in didSelect method) get it from searched Food. But for that to work properly you should assign searched food with food initially and also when the user clears search bar you should again reset searched food to food data.

Answer 5

Please try like this,
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if searching {
print(searchedFoods[indexPath.row])
} else {
print(foods[indexPath.row])
}
}

Try This
extension FoodViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
if searching {
let food = searchedFoods[indexPath.row]
cell.textLabel?.text = food.title
} else {
let food = foods[indexPath.row]
cell.textLabel?.text = food.title
}
return cell
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searching {
return searchedFoods.count
} else {
return foods.count
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if searching {
let meal = searchedFoods[indexPath.row]
let labelContent = meal
print(labelContent)
} else {
let meal = foods[indexPath.row]
let labelContent = meal
print(labelContent)
}
}
