PFQueryTableView Controller not loading custom Cells - xcode

Question

Im working on an app and I would like it to populate the cells based on users who are within a set distance from the currentuser. For some reason the customcells are not being populated with the correct objects. The labels and images that are supposed to be retrieved are blank. All i get is a blank cell. I made sure i gave the cell identifier the correct name, and i also made sure to link the tableviewcontroller and the tablecellview to their respective classes,but still no luck.
first i created initializers:
class TableViewController: PFQueryTableViewController, CLLocationManagerDelegate {
let locationManager = CLLocationManager()
var currLocation: CLLocationCoordinate2D?
override init!(style: UITableViewStyle, className: String!) {
super.init(style: style, className: className)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.parseClassName = "User"
self.textKey = "FBName"
// self.imageKey = "pictureURL"
self.pullToRefreshEnabled = true
self.objectsPerPage = 10
self.paginationEnabled = true
}
Then in viewDidLoad i enabled location services:
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.estimatedRowHeight = 200
self.locationManager.requestWhenInUseAuthorization()
if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
loadData()
println("location services enabled bruh")
}
}
Next i overrode the queryfortable function:
override func queryForTable() -> PFQuery! {
let query = PFQuery(className: "User")
if let queryLoc = currLocation {
query.whereKey("location", nearGeoPoint: PFGeoPoint(latitude: queryLoc.latitude, longitude: queryLoc.longitude), withinMiles: 50)
query.limit = 40
query.orderByAscending("createdAt")
println("\(queryLoc.latitude)")
return query
} else {
query.whereKey("location", nearGeoPoint: PFGeoPoint(latitude: 37.411822, longitude: -121.941125), withinMiles: 50)
query.limit = 40
query.orderByAscending("createdAt")
println("else statement")
return query
}
}
then the objectAtIndexPath function
override func objectAtIndexPath(indexPath: NSIndexPath!) -> PFObject! {
var obj : PFObject? = nil
if indexPath.row < self.objects.count {
obj = self.objects[indexPath.row] as? PFObject
}
return obj
}
and lastly I returned the cell, but for some reason it does not work:
override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!, object: PFObject?) -> PFTableViewCell! {
let cell = tableView.dequeueReusableCellWithIdentifier("CustomCell", forIndexPath: indexPath) as TableViewCell
cell.userName?.text = object?.valueForKey("FBName") as? String
let userProfilePhotoURLString = object?.valueForKey("pictureURL") as? String
var pictureURL: NSURL = NSURL(string: userProfilePhotoURLString!)!
var urlRequest: NSURLRequest = NSURLRequest(URL: pictureURL)
NSURLConnection.sendAsynchronousRequest(urlRequest, queue: NSOperationQueue.mainQueue()) { (NSURLResponse response, NSData data,NSError error) -> Void in
if error == nil && data != nil {
cell.userImage?.image = UIImage(data: data)
}
}
cell.ratingsView?.show(rating: 4.0, text: nil)
return cell
}
ps, i have the number of sections set to 1, just didnt think that method would be useful to show here.

Answer 1

okay I found the issue! The issue was that I was trying to use PFQuery in order to retrieve a list of PFUsers. I found out that cannot be done using PFQuery infact PFUser has it's own query method for retrieving information from its users.
all i had to do was replace this line:
let query = PFQuery(className: "User")
with this:
let query = PFUser.query()
