Я пытаюсь создать новый объект класса Student, но есть ошибка, когда я вызываю функцию createnewStudent поговоркуСоздание нового экземпляра класса NSManagedObject
не может ссылаться на «CreateStudent» со списком аргументов типа '(NSManagedObjectContext, комбинация: String, stream: String, name: String, DOB: NSDate, пол: UISegmentedControl !, DOA: NSDate, имя отца: UITextField, mothername: UITextField, familyincome: Int, emailid: String, phonenumber: Int)'
Как это сделать?
Это мой ViewController.swift файл:
import UIKit
import CoreData
class PortalViewController: UIViewController,UITextFieldDelegate {
@IBOutlet weak var coursePicker: UIPickerView!
@IBOutlet weak var combination: UILabel!
@IBOutlet weak var streamPrint: UILabel!
@IBOutlet weak var genderSelected: UISegmentedControl!
@IBOutlet weak var DOB: UIDatePicker!
@IBOutlet weak var studentName: UITextField!
@IBOutlet weak var fatherName: UITextField!
@IBOutlet weak var fathersIncome: UITextField!
@IBOutlet weak var mothersName: UITextField!
@IBOutlet weak var mothersIncome: UITextField!
@IBOutlet weak var phoneNumber: UITextField!
@IBOutlet weak var emailID: UITextField!
var newStudent = Student()
let managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext
let stream = ["Science","Arts","Commerce"]
let combinationScience = ["PCM", "PMCs", "CBZ"]
let combinationArts = ["HEP","English","Kannada"]
let combinationCommerce = ["BBM", "Economics","xyz"]
var selectedRow = 0
func pickerView(pickerView : UIPickerView , didSelectRow row : Int , inComponent component : Int){
switch component {
case 0 :
selectedRow = row
streamPrint.text = stream[row]
coursePicker.reloadAllComponents()
case 1 :
switch selectedRow {
case 0: combination.text = combinationScience[row]
case 1: combination.text = combinationArts[row]
case 2: combination.text = combinationCommerce[row]
default : combination.text = "combination"
}
default : selectedRow = 0
}
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 2
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return 3
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
switch component {
case 0 : return stream[row]
case 1 :
switch selectedRow {
case 0: return combinationScience[row]
case 1: return combinationArts[row]
case 2: return combinationCommerce[row]
default: return nil
}
default: return nil
}
}
@IBAction func proceed(sender: AnyObject) {
var fi1 = fathersIncome.text.toInt()
var fi2 = mothersIncome.text.toInt()
var fi = fi1! + fi2!
var newStudent = Student.CreateStudent(managedObjectContext!, combination: combination.text!, stream: streamPrint.text!, name: studentName.text!, DOB: DOB.date, gender: genderSelected, DOA: DOB.date, fathername: fatherName!, mothername: mothersName!, familyincome: fi, emailid: emailID.text!, phonenumber: phoneNumber.text.toInt()!)
