请帮助，我无法将parse对象从注释Query传递到destinationViewController。当用户点击注释视图时，它将用户带到destinationVC，但无论用户点击哪个注释，它都会传递相同的对象。我认为它与prepareForSegue函数有关。请让我知道我做错了什么。
继承我的代码：
class MapSearchViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {
@IBOutlet weak var mapView: MKMapView!
var jobPosts = [PFObject]()
var jobPost: PFObject?
let locationManager = CLLocationManager()
var currentLoc: PFGeoPoint! = PFGeoPoint()
override func viewDidLoad() {
super.viewDidLoad()
//MARK new added code Start--
self.mapView.delegate = self
self.mapView.setUserTrackingMode(MKUserTrackingMode.Follow, animated: true)
//MARK new added code End--
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
//Snippet For Blue Current Location Dot:
//self.mapView.showsUserLocation = true
}
//MARK: -- Location Delegate Methods
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1))
self.mapView.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Errors: " + error.localizedDescription)
}
//MARK: OCT 26
override func viewDidAppear(animated: Bool) {
let annotationQuery = PFQuery(className: "JobPost")
currentLoc = PFGeoPoint(location: locationManager.location)
annotationQuery.whereKey("location", nearGeoPoint: currentLoc, withinMiles: 100)
annotationQuery.findObjectsInBackgroundWithBlock {
(posts, error) -> Void in
if error == nil {
// The find succeeded.
print("Successful query for annotations")
let jobPosts = posts as [PFObject]!
for post in jobPosts {
let point = post["location"] as! PFGeoPoint
var annotation = MKPointAnnotation()
annotation.coordinate = CLLocationCoordinate2DMake(point.latitude, point.longitude)
self.mapView.addAnnotation(annotation)
annotation.title = post["job"] as! String
let pay = post["price"] as! String
let payLabel = "\(pay)$"
annotation.subtitle = payLabel
let btn = UIButton(type: .DetailDisclosure)
self.jobPost = post
}
} else {
// Log details of the failure
print("Error: \(error)")
}
}
}
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
var view = mapView.dequeueReusableAnnotationViewWithIdentifier("annotationIdentifier")
if view == nil {
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "annotationIdentifier")
view?.canShowCallout = true
view?.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure)
} else {
view?.annotation = annotation
}
return view
}
var selectedAnnotation: MKPointAnnotation!
func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
selectedAnnotation = view.annotation as? MKPointAnnotation
performSegueWithIdentifier("annotationSender", sender: self)
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let destination = segue.destinationViewController as? JobDetailViewController {
destination.currentObject = jobPost
}
}
}
detailVC的代码：
class JobDetailViewController: UIViewController, MFMailComposeViewControllerDelegate {
@IBOutlet weak var jobTitleLabel: UILabel!
@IBOutlet weak var priceLabel: UILabel!
@IBOutlet weak var distanceLabel: UILabel!
@IBOutlet weak var jobDescriptionContent: UITextView!
@IBOutlet weak var pictureImageView: UIImageView!
var jobPosts:[PFObject]!
var currentObject : PFObject?
var distance = "7"
var annotation = MKPointAnnotation()
override func viewDidLoad() {
super.viewDidLoad()
self.distanceLabel.text = "\(distance) miles away"
if let object = currentObject {
jobTitleLabel.text = object["job"] as! String
priceLabel.text = object["price"] as! String
jobDescriptionContent.text = object["description"] as! String
}
}
