I have built a Tableview that shows data called from an API (I mention this because maybe my problem is due to reloadData()).
However, the format of my data is simple (a struct) and I found an answer that addresses my question here.
But this didn't work for me. I'm not sure why. My code gets built and there are no errors, but when I search for something, nothing happens.
Here's what my code looks like:
import UIKit
class UsersViewController: UIViewController, UITableViewDelegate, UITableViewDataSource
@IBOutlet weak var searchBar: UISearchBar!
@IBOutlet weak var dataTableView: UITableView!
var userData: [User] = [
User(name: "name1", email: "email1", age: 25),
User(name: "name2", email: "email2", age: 25),
User(name: "name3", email: "email3", age: 25)
]
var searchedUser = [User]()
var searchActive = false
override func viewDidLoad()
super.viewDidLoad()
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
let cell = dataTableView.dequeueReusableCell(withIdentifier: "userCell", for: indexPath) as! UsersTableViewCell
if searchActive
cell.userName.text = self.searchedUser[indexPath.row].name // Maybe my error is that I'm just searching for their usernames, but that's what I want
else
cell.userName.text = self.userData[indexPath.row].name
return cell
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
if searchActive
return self.searchedUser.count
else
return self.userData.count
extension UsersViewController: UISearchBarDelegate
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String)
searchedUser = userData.filter(user) -> Bool in
return user.name.range(of: searchText, options: [ .caseInsensitive ]) != nil
searchActive = true
self.dataTableView.reloadData()
What have I done wrong?
