Passing data between view controllers

Closed 2 years ago.
Right now I have a table view and another view controller. I would like to use the didSelectRowAt function to show a detailed view of the tableview cell on the new view controller. How would I pass data from the the tableview cell to a new view controller? Here is what I currently have.
This is the code for my main view controller.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var searchBar: UISearchBar!
#IBOutlet weak var tableView: UITableView!
struct data {
var sectionTitle = String()
var rowTitles = [String]()
}
var dataArray = [data(sectionTitle: "section 1", rowTitles: ["row 1", "row 2", "row 3"]),
data(sectionTitle: "section 2", rowTitles: ["row 1", "row 2"]),
data(sectionTitle: "section 3", rowTitles: ["row 1"])
]
var searchArray = [(sectionTitle: String, rowTitles: [String])]()
var searching = false
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
}
extension ViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searching {
return searchArray[section].rowTitles.count
} else {
return dataArray[section].rowTitles.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "searchCell")
if searching {
cell?.textLabel?.text = self.searchArray[indexPath.section].rowTitles[indexPath.row]
} else {
cell?.textLabel?.text = self.dataArray[indexPath.section].rowTitles[indexPath.row]
}
return cell!
}
func numberOfSections(in tableView: UITableView) -> Int {
return dataArray.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
if searching {
return searchArray.count
} else {
return dataArray[section].sectionTitle
}
}
}
This is the code for my second view controller so far.
import UIKit
class secondViewController: UIViewController {
#IBOulet weak var nameLabel: UILabel!
#IBOulet weak var descriptionLabel: UILabel!
#IBOulet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func visitButtonTapped(_ sender: Any) {
}
}
Here is my current Storyboard.

Answer 1

Create a model in your ViewController
import UIKit
class secondViewController: UIViewController {
#IBOulet weak var nameLabel: UILabel!
#IBOulet weak var descriptionLabel: UILabel!
#IBOulet weak var imageView: UIImageView!
var titleOfItem : String
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func visitButtonTapped(_ sender: Any) {
}
}
In your tableView delegate
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// Init you secondVC
secondVC.titleOfItem = searchArray[indexPath.section].rowTitles[indexPath.row]
// pushToVC / Present
}
