如何下载我的对象? (旧Xcode版本中的选项问题)

由于我使用Xcode 6.2开发了这个应用程序,我发现了一些问题,很多都解决了,但是这一个,可能需要重新构建我的应用程序。 在下面的代码中, filterByProximity 函数会出错。 我支持是一个选项问题(Nils Ziehn警告我here关于它的问题)。另一位开发人员告诉我:“使用缓存下载位置对象,然后进行查询”。

嗯,有可能吗?我该怎么做?在这里我的代码:

import UIKit
import MapKit
import CoreLocation

class MapViewController: UIViewController, CLLocationManagerDelegate {


    @IBOutlet weak var mapView: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.

        var locationManager = CLLocationManager()

        var lat = locationManager.location.coordinate.latitude
        var lon = locationManager.location.coordinate.longitude

        let location = CLLocationCoordinate2D(latitude: lat, longitude: lon)
        let span = MKCoordinateSpanMake(0.05, 0.05)
        let region = MKCoordinateRegionMake(location, span)
        mapView.setRegion(region, animated: true)

        let anotation = MKPointAnnotation()
        anotation.setCoordinate(location)
        anotation.title = "my title"
        anotation.subtitle = " my subtitle"

        mapView.addAnnotation(anotation)

        println("****** Welcome in MapViewController")



        //MARK: (471) Crossing Positions
        //*******************************************************

        let myGeoPoint = PFGeoPoint(latitude: lat, longitude:lon)
        let myParseId = PFUser.currentUser().objectId //PFUser.currentUser().objectId

        println("****** this is my geoPoint from map view controller: \(myGeoPoint)")


//        
//        var inspector = PFQuery(className:"GameScore")
//                inspector.saveInBackgroundWithBlock {
//                    (success: Bool, error: NSError?) -> Void in
//                    if (success) {
//                        // The object has been saved.
//                        var the = inspector.objectId
//                    } else {
//                        // There was a problem, check error.description
//                    }
//                }

//        func filterByProximity() {
//            PFQuery(className: "Position")
//                .whereKey("where", nearGeoPoint: myGeoPoint, withinKilometers: 500.0)     //(474)
//            .findObjectsInBackgroundWithBlock ({
//                objects, error in
//                if let proximityArray = objects as? [PFObject] {
