Swift 2.2, RealmSwift - Retrieval of data not working - ios

Question

I am using realm for my notepad app to store the array noteTitles, which is of a custom class Note. The app works fine, but when it is supposed to save, it doesn't pass through. When I restart the app, the notes are gone. I will give code to all of the files. Also, I want the user to add notes and I need the ObjectForPrimaryKey to update everytime so a new id is created for each note.
Note Class Code:
import Foundation
import RealmSwift
class Note: Object {
dynamic var title = ""
var content = ""
var id = 0
override class func primaryKey() -> String? {
print("id generated")
return "id"
}
}
ViewController(Where I write the notes) Code:
import UIKit
import RealmSwift
var note2 = Note()
var note: Note!
let realm = try! Realm()
class ViewController3: UIViewController, UITextViewDelegate {
var note: Note!
#IBOutlet var noteText: UITextView!
#IBOutlet var noteTitle: UITextField!
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
noteTitle.text = note.title
noteText.text = note.content
}
override func viewWillDisappear(animated: Bool) {
super.viewWillDisappear(animated)
note.title = noteTitle.text!
note.content = noteText.text
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func textViewDidEndEditing(textView: UITextView) {
func noteEnded(note2: Note) {
note2.title = note.title
note2.content = note.content
note2.id = note.id
do {
try realm.write {
realm.add(noteTitles, update: true)
print("added")
}
} catch {
print("There was a problem")
}
}
print("editing ended")
}
override func viewDidLoad() {
super.viewDidLoad()
print(note2.id)
self.noteText.delegate = self
// Do any additional setup after loading the view.
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
noteTitle.resignFirstResponder()
noteText.resignFirstResponder()
}
}
TableViewController(Note List) Code:
import UIKit
import RealmSwift
var noteTitles:[Note] = []
class TableViewController: UITableViewController {
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return noteTitles.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.text = noteTitles[indexPath.row].title // error here
// Configure the cell...
return cell
}
override func viewDidAppear(animated: Bool) {
tableView.reloadData()
}
override func viewDidLoad() {
super.viewDidLoad()
sleep(2)
if realm.objectForPrimaryKey(Note.self, key: 0) != nil {
realm.objectForPrimaryKey(Note.self, key: 0)
}
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == UITableViewCellEditingStyle.Delete {
noteTitles.removeAtIndex(indexPath.row)
tableView.reloadData()
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier! == "editNote" {
let noteDetailViewController = segue.destinationViewController as! ViewController3
let selectedIndexPath = tableView.indexPathForSelectedRow
noteDetailViewController.note = noteTitles[selectedIndexPath!.row]
} else if segue.identifier! == "addNote" {
let note = Note()
noteTitles.append(note)
let noteDetailViewController = segue.destinationViewController as! ViewController3
noteDetailViewController.note = note
}
}
}
Thanks in advance!

The function noteEnded should not inside the textViewDidEndEditing and it is not being called.
Try this
func noteEnded(note2: Note) {
do {
try realm.write {
realm.add(note2, update: true)
print("added")
}
} catch {
print("There was a problem")
}
}
func textViewDidEndEditing(textView: UITextView) {
note2.title = note.title
note2.content = note.content
note2.id = note.id
noteEnded(note2)
print("editing ended")
}
It is also better to have "Done" button to save the note. Easy to handle the input and save.
