I need to pass data to a table on another screen, in this case vehicle, check detail.
the vehicle as title and the detail as subtitle in the first table and likewise the options selected in the table should be assigned to the vehicle and displayed on the screen below In the bottom view, in theory, a table should appear that shows the options selected for each car in the previous screen.
It's a little bit of a description of what you want, but if I understood correctly, you would basically need to have a protocol:
protocol AddCarProtocol: class {
func didSaveNewCar(car: Car)
}
and a variable weak var delegate: AddCarProtocol? that your driver would have to add cars and that you would set from the controller that shows the list of cars, in prepareForSegue if you use segues .
You could define a structure Car to contain the information of a car:
struct Car {
var name: String
var checkDetail: String
var checkPoints: [String]
}
So in your driver to add cars, you could have an array with possible checkpoints:
let availableCheckPoints = ["Alineacion", "Balanceo", "Cambio aceite", "Mantenimiento A/C"]
thus your method to save the car:
@IBAction func doSaveCar(_ sender: Any) {
guard let carName = self.tfCar.text, let checkDetail = self.tfDetail.text else {
return
}
let checkPoints = self.getSelectedCheckPoints()
let car = Car(name: carName, checkDetail: checkDetail, checkPoints: checkPoints)
self.delegate?.didSaveNewCar(car: car)
_ = self.navigationController?.popViewController(animated: true)
}
private func getSelectedCheckPoints() -> [String] {
if let selectedIndexPaths = self.tableview.indexPathsForSelectedRows {
var selectedCheckpoints: [String] = []
selectedIndexPaths.forEach({ (indexPath) in
selectedCheckpoints.append(self.availableCheckPoints[indexPath.row])
})
return selectedCheckpoints
}
return []
}
So in your viewController of the car list, you would have the delegated method:
extension ViewController: AddCarProtocol {
func didSaveNewCar(car: Car) {
self.cars.append(car)
self.tableview.reloadData()
}
}
and finally to move to the controller that shows the details of a car:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.performSegue(withIdentifier: "showCarDetailsVC", sender: self.cars[indexPath.row])
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showAddCarViewController" {
let vc = segue.destination as? AddCarViewController
vc?.delegate = self
}
else if segue.identifier == "showCarDetailsVC" {
let vc = segue.destination as? CarDetailViewController
vc?.car = sender as? Car
}
}
and you would have available the data of the selected car, to show them in the controller in viewDidLoad for example.
