Notes will not delete - ios

Question

I have a note part of my app which I am able to create note and edit notes but when it comes to deleting notes I have an issue. I can delete them from the table view itself and all notes but when I reload the app they're back as if they're sticking in the dictionary. Could you pleas etell me a way to delete them permanently. I have three controllers, only two being relevant. Here are the relevant ones:
MasterViewController.swift
import UIKit
class MasterViewController: UITableViewController {
#IBOutlet weak var menuButton: UIBarButtonItem!
override func awakeFromNib() {
super.awakeFromNib()
}
override func viewDidLoad() {
super.viewDidLoad()
Note.loadnotes()
noteTable = self.tableView
// Side Menu
if self.revealViewController() != nil {
menuButton.target = self.revealViewController()
menuButton.action = "revealToggle:"
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
// Do any additional setup after loading the view, typically from a nib.
func insertNewObject(sender: AnyObject) {
allNotes.insert(Note(), atIndex: 0)
let indexPath = NSIndexPath(forRow: 0, inSection: 0)
self.tableView.insertRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
self.performSegueWithIdentifier("showDetail", sender: self)
}
// MARK: - Segues
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "showDetail" {
if let indexPath = self.tableView.indexPathForSelectedRow() {
let object: Note = allNotes[indexPath.row] as Note
currentNoteIndex = indexPath.row
}
else {
currentNoteIndex = 0
}
}
}
// MARK: - Table View
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return allNotes.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell
let object: Note = allNotes[indexPath.row]
as Note; cell.textLabel!.text = object.note
return cell
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == .Delete {
allNotes.removeAtIndex(indexPath.row)
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
} else if editingStyle == .Insert {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}
}
note.swift
import UIKit
var allNotes:[Note] = []
var currentNoteIndex:NSInteger = -1
var noteTable:UITableView?
let KAllNotes:String = "notes"
class Note: NSObject {
var date:String
var note:String
override init() {
date = NSDate().description
note = ""
}
func dictionary() -> NSDictionary {
return ["note":note, "date":date]
}
class func saveNotes() {
var aDictionaries:[NSDictionary] = []
for (var i:NSInteger = 0; i < allNotes.count; i++) {
aDictionaries.append(allNotes[i].dictionary())
}
NSUserDefaults.standardUserDefaults().setObject(aDictionaries, forKey: KAllNotes)
// aDictionaries.writeToFile(filePath(), atomically: true)
}
class func loadnotes() {
var defaults:NSUserDefaults = NSUserDefaults.standardUserDefaults()
var savedData:[NSDictionary]? = defaults.objectForKey(KAllNotes) as? [NSDictionary]
// var savedData:NSArray? = NSArray(contentsOfFile: filePath())
if let data:[NSDictionary] = savedData {
for (var i:NSInteger = 0; i < data.count; i++) {
var n:Note = Note()
n.setValuesForKeysWithDictionary(data[i] as [NSObject : AnyObject])
allNotes.append(n)
}
}
}
class func filePath() -> String {
var d:[String]? = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String]
if let directories:[String] = d {
var docsDirectory:String = directories[0]
var path:String = docsDirectory.stringByAppendingPathComponent("\(KAllNotes).notes")
return path;
}
return ""
}
}
Thanks in advance

In the master view controller use this altered function:
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == .Delete {
allNotes.removeAtIndex(indexPath.row)
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
Note.saveNotes()
} else if editingStyle == .Insert {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}
This will force the dictionary to be re-saved. using your save notes function in notes.swift
