Querying an array to populate a table view in Swift using Parse - ios

Question

I'm querying a Parse class for the current user's username. The class column is named Attendants and the array definitely contains the username. When the code is ran, the table isn't populated and no errors are thrown.
Would anybody be able to point out what I'm doing wrong?
Necessary code is shown below:
class EventsViewController: PFQueryTableViewController{
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// Initialise the PFQueryTable tableview
override init!(style: UITableViewStyle, className: String!) {
super.init(style: style, className: className)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
// Configure the PFQueryTableView
self.parseClassName = "Event"
self.textKey = "username"
self.pullToRefreshEnabled = true
self.paginationEnabled = false
}
// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery! {
var query = PFQuery(className: "Event")
var tempname = PFUser.currentUser().username
NSLog(tempname)
query.whereKey("Attendants", equalTo: tempname)
return query
}
//override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! PFTableViewCell!
if cell == nil {
cell = PFTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
cell.selectionStyle = UITableViewCellSelectionStyle.None
}
// Extract values from the PFObject to display in the table cell
cell?.textLabel?.text = object["EventName"] as! String!
cell?.detailTextLabel?.text = object["EventName"] as! String!
cell.selectionStyle = UITableViewCellSelectionStyle.None
return cell
}
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using [segue destinationViewController].
var detailScene = segue.destinationViewController as! EventDetailViewController
// Pass the selected object to the destination view controller.
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = objects[row] as? PFObject
}
}
override func viewDidAppear(animated: Bool) {
// Refresh the table to ensure any data changes are displayed
tableView.reloadData()
}
}

All you need to do is write the queryForTable() function.
All your tableView functions are never called.
So something about this would be solution:
class EventsViewController: PFQueryTableViewController {
override init(style: UITableViewStyle, className: String?) {
super.init(style: style, className: className)
self.textKey = "YOUR_PARSE_COLOMN_YOU_WANT_TO_SHOW"
self.pullToRefreshEnabled = true
self.paginationEnabled = false
}
required init!(coder aDecoder: NSCoder!) {
super.init(coder: aDecoder)
}
override func queryForTable() -> PFQuery {
var query = PFQuery(className: "Event")
var tempname = PFUser.currentUser()!.username
NSLog(tempname!)
// This is really ugly.. Please do this via Pointer and not via String.
query.whereKey("Attendants", equalTo: tempname!)
return query
}
}
If you want to use custom cells, you need to create your own TableViewController and implement the logic on the TableViewController itself.
This code is tested in Xcode 6.3 (swift 1.2)
Please keep in mind that you need to init the tableViewController out of the code, like:
var eventsvc = EventsViewController(style: .Plain, className: "Event")
to present it out of a viewcontroller:
self.presentViewController(eventsvc, animated: true, completion: nil)
If you want to use is it in a storyboard see this
