Table cells not in order using parse Swift - ios

Question

I'm using parse to make a simple notes app. When I save a note the cells appear in a random order in the table view. Can anyone help me figure out how to fix this so the cells are in order from when I saved a note. Thanks!
import UIKit
class MasterTableViewController: UITableViewController, PFLogInViewControllerDelegate, PFSignUpViewControllerDelegate {
var noteObjects: NSMutableArray! = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
// 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 viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if (PFUser.currentUser() == nil) {
}else {
self.fetchAllObjectsFromLocalDatastore()
self.fetchAllObjects()
}
}
func fetchAllObjectsFromLocalDatastore() {
var query: PFQuery = PFQuery(className: "Note")
query.fromLocalDatastore()
query.whereKey("username", equalTo: PFUser.currentUser()!.username!)
query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
if (error == nil) {
var temp: NSArray = objects!; NSArray.self
self.noteObjects = temp.mutableCopy() as! NSMutableArray
self.tableView.reloadData()
}else {
}
}
}
func fetchAllObjects() {
PFObject.unpinAllObjectsInBackgroundWithBlock(nil)
var query: PFQuery = PFQuery(className: "Note")
query.whereKey("username", equalTo: PFUser.currentUser()!.username!)
query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
if (error == nil) {
PFObject.pinAllInBackground(objects, block: { (success, error) in
if error == nil {
self.fetchAllObjectsFromLocalDatastore()
}
})
}else {
println(error!.userInfo)
}
}
}

super.didReceiveMemoryWarning()

// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

// Return the number of sections.
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
return self.noteObjects.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! MasterTableViewCell
var object: PFObject = self.noteObjects.objectAtIndex(indexPath.row) as! PFObject
cell.masterTitleLabel?.text = object["title"] as? String
cell.masterTextLabel?.text = object["text"] as? String
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.performSegueWithIdentifier("editNote", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var upcoming: AddNoteTableViewController = segue.destinationViewController as! AddNoteTableViewController
if (segue.identifier == "editNote") {
let indexPath = self.tableView.indexPathForSelectedRow()!
var object: PFObject = self.noteObjects.objectAtIndex(indexPath.row) as! PFObject
upcoming.object = object
self.tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
}
}

What you need is to set a sorting for your query.
You can sort it by the UpdatedAt date with the following line of code:
query.ascending("updatedAt");
