This code gives me the result of savings but is also adding deleted records to the total point? How do I prevent deleted records to be added to the total.
import UIKit
import CoreData
class TotalPointsViewController: UIViewController {
var points = [Aktie]()
@IBOutlet weak var totalPoints: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let context: NSManagedObjectContext = appDelegate.persistentContainer.viewContext
let request = NSFetchRequest<NSFetchRequestResult>(entityName: "Aktie")
do {
let points: NSArray = try context.fetch(request) as NSArray
var sum = 0
for result in points {
sum += Int((result as AnyObject).point ?? "0") ?? 0
}
totalPoints.text = "\(sum)"
}
catch {
print("Fetch Failed")
}
}
}

I have managed to add the following code to remember the value in the stepper.
counterStepper.value=value counterTF.text=String(describing: value)
I added the following code to the stepper.
@IBAction func counterStepperPressed(_ sender: UIStepper) {
counterTF.text=String(describing: sender.value) UserDefaults.standard.setValue(sender.value, forKey: "counterStepper") NotificationCenter.default.post(Notification.init(name: Notification.Name("StepperDidChangeValue")))
}
The only issue I have is that if I edit a second item it remembers the value of the first item. Somehow it is not remembering the original value of the second item.
I have tried the code in both answers - I also positioned the code where I calculate the total points between various brackets but it is not showing any results in my viewcontroller. There are no coding errors in both solutions. There is data in my records.
import CoreData
class TotalPointsViewController: UIViewController {
@IBOutlet weak var totalPoints: UITextField!
var points = [Aktie]()
var firstLoad = true
override func viewDidLoad() {
super.viewDidLoad()
if firstLoad
{
firstLoad = false
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let context: NSManagedObjectContext = appDelegate.persistentContainer.viewContext
let request = NSFetchRequest<NSFetchRequestResult>(entityName: "Aktie")
do {
let results: NSArray = try context.fetch(request) as NSArray
for result in results {
let aktie = result as! Aktie
points.append(aktie)
}
}
catch
{
print("Fetch Failed")
}
}
}
func calculateSumPoints() {
let sum = points.compactMap { $0.point }
.reduce(0) { previous, next in
guard let value = Int(next) else { return previous }
return previous + value
}
totalPoints.text = "\(sum)"
}
}
I use the actionGoal in the data model as a section:
// Table View Sections
func numberOfSections(in tableView: UITableView) -> Int {
return result?.data3.count ?? 0
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return result?.data3[section].actionGoal
}
And then the tableView:
// Table View
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let result = result {
return result.data3[section].actions.count
}
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let action = result?.data3[indexPath.section].actions[indexPath.row]
let cell = ActionTableView.dequeueReusableCell(withIdentifier: "ActionCell", for: indexPath) as! ActionTableCell
cell.ActionTitle.text = action?.actionTitle
cell.ActionImage.image = UIImage(named: action!.actionImage)
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 80
}
// This code is for the transfer to the next page
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
index = 0
performSegue(withIdentifier: "showDetail", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? ActionDetailViewController {
destination.action = result?.data3[index].actions[(tableView.indexPathForSelectedRow?.row)!]
}
The segue is working if I add:
var indexdata = 0
and add at didSelectRow
indexdata = 0
but the first row in the second section in the segue is showing the detail of the first section.
The segue is now working but it does not show the right detail with the second section.
If I change the indexData = 0 to 1 it does, but then the first section does not work.
