我已经看到了这些问题的变体，但是没有适用于我如何设置代码的答案。我对解决方案感到困惑，并且我已经立即完成了这个项目。所以，我正在寻求帮助。
我想做的是：
从我的Firebase阵列中拉出坐标，设置如下：FireBase Setup
我的主要Feed是这样的：

class FeedVC: UIViewController, UITableViewDelegate, UITableViewDataSource, MKMapViewDelegate, CLLocationManagerDelegate {
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var mapView: MKMapView!
let locationManager = CLLocationManager()
var centerMapped = false
var geoFire: GeoFire!
var posts = [Post]()
override func viewDidLoad() {
super.viewDidLoad()
mapView.delegate = self
mapView.userTrackingMode = MKUserTrackingMode.follow
tableView.delegate = self
tableView.dataSource = self
DataService.ds.REF_VENUE.observe(.value, with: { (snapshot) in
self.posts = [] // THIS IS THE NEW LINE
if let snapshot = snapshot.children.allObjects as? [DataSnapshot] {
for snap in snapshot {
if let postDict = snap.value as? Dictionary<String, AnyObject> {
let key = snap.key
let post = Post(postKey: key, postData: postDict)
self.posts.append(post)
}
if let locationDict = snap.value as? Dictionary<String, AnyObject> {
let lat = locationDict["LATITUDE"] as! CLLocationDegrees
let long = locationDict["LONGITUDE"] as! CLLocationDegrees
let center = CLLocationCoordinate2D(latitude: lat, longitude: long)
_ = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.10, longitudeDelta: 0.10))
print(lat,long)
}
}
}
self.tableView.reloadData()
})
}
//Brings up the user on the map after authorization
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
locationAuthStatus()
}
//Checks if app is authorized to get user's location data.
func locationAuthStatus () {
if CLLocationManager.authorizationStatus() == .authorizedWhenInUse {
mapView.showsUserLocation = true
} else {
locationManager.requestWhenInUseAuthorization()
}
}

if status == .authorizedWhenInUse {
mapView.showsUserLocation = true
}
}
func centerMapOnLocation(location: CLLocation) {
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate, 1000, 1000)
mapView.setRegion(coordinateRegion, animated: true)
}

}
}
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
var annotationView: MKAnnotationView?
if annotation.isKind(of: MKUserLocation.self) {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "User")
annotationView?.image = UIImage(named: "icon")
}
return annotationView
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return posts.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = tableView.dequeueReusableCell(withIdentifier: "detailCell", for: indexPath) as? PostCell {
let cellData = posts[indexPath.row]
cell.configureCell(post: cellData)
return cell
} else {
return PostCell()
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let post = posts[indexPath.row]
performSegue(withIdentifier: "previewSegue", sender: post)
}

if let destination = segue.destination as? PreviewVC {
if let update = sender as? Post, let update2 = sender as? Post {
destination.locationData = update
destination.addressData = update2
}
}
}
}
我的代码运行，我可以打印Lat和Long，但我不知道如何将它们添加到地图中。我应该制作另一个VC并将数据放入那里吗？我不知道该改变什么，但是，我还需要帮助！
答案 0 :(得分：4)
在print(lat,long)
let annotation = MKPointAnnotation()
annotation.coordinate = CLLocationCoordinate2DMake(lat, long)
annotation.title = "Hello!" // if you need title, add this line
self.mapView.addAnnotation(annotation)
