My New ViewController is giving SIGABRT error? - ios

Question

I have many different buttons like UIStepper and DatePicker and a MapView. Can anyone help me get my whole view controller and the button working. I have been getting an error about SIGABRT. It say's "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Field_Service_Report.AddController hoursStepper:]: unrecognized selector sent to instance 0x7fb5d7c8d010'"
This is my View Controller code :
import UIKit
import MapKit
import CoreLocation
class AddController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {
#IBOutlet weak var hoursStepperResult: UILabel!
#IBOutlet weak var hoursStepper: UIStepper!
#IBOutlet weak var minutesStepperResult: UILabel!
#IBOutlet weak var minutesStepper: UIStepper!
#IBOutlet weak var currentLocationLabel: UILabel!
#IBOutlet weak var dateOfReport: UIDatePicker!
#IBOutlet weak var mapView: MKMapView!
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Start Map Contents
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
self.mapView.showsUserLocation = true
// End Map Contents
}
// Start Stepper Contents
#IBAction func hoursStepperAction(_ sender: UIStepper) {
hoursStepperResult.text = String(Int(sender.value))
}
#IBAction func minutesStepperAction(_ sender: UIStepper) {
minutesStepperResult.text = String(Int(sender.value))
}
// End Stepper Contents
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// Here is the new code its giving me 3 erroe because im trying to get the text and numbers from another ViewController to print out in this VC.
#IBAction func doneACButton(_ sender: AnyObject) {
let newVC = storyboard?.instantiateViewController(withIdentifier: "ResultController") as! ResultController
newVC.intPassed = hoursIntProvided
newVC.intPassed = minutesIntProvided
newVC.stringPassed = resultedHours.text!
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1))
self.mapView.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Errors: " + error.localizedDescription)
}
// MARK: - Navigation
}

Answer 1

Notice the colon right here in the method signature:
-[Field_Service_Report.AddController hoursStepper:]
^
This is the signature of a method that takes a parameter, not the signature of an accessor. Are you sure you didn't misspell a selector name somewhere or leave something accidentally connected in IB that should have been removed? (Perhaps if you renamed a method and forgot to redo the action connection?)
