I tried this code, here I increase MKCoordinateSpan to 200 - 200, but my application got crashed, can someone please help me.
func setupMap(hotelListData:[HotelListData], cityLocation:
CLLocationCoordinate2D )
{
let coordinateRegion = MKCoordinateRegion(center: cityLocation, span: MKCoordinateSpan(latitudeDelta: 200, longitudeDelta: 200))
mapView.setRegion(coordinateRegion, animated: true)
//Set Multiple Annotation
for data in hotelListData {
let annotation = MKPointAnnotation()
annotation.title = data.hotel?.name
annotation.coordinate = CLLocationCoordinate2D(latitude: Double(data.hotel?.latitude ?? 0.0), longitude: Double(data.hotel?.longitude ?? 0.0))
mapView.addAnnotation(annotation)
}
}
Update:
I changed span from (latitudinalMeters & longitudinalMeters) and got the desired results :-
Now one can found here :
i)Set multiple Annotations to apple maps.
ii)Adjust Zoom with the desired location.
func setupMap(hotelListData:[HotelListData], cityLocation:
CLLocationCoordinate2D ){
let coordinateRegion = MKCoordinateRegion(center: cityLocation, latitudinalMeters: CLLocationDistance(exactly: 15000)!, longitudinalMeters: CLLocationDistance(exactly: 15000)!)
mapView.setRegion(coordinateRegion, animated: true)
//Set Multiple Annotation
for data in hotelListData {
let annotation = MKPointAnnotation()
annotation.title = data.hotel?.name
annotation.coordinate = CLLocationCoordinate2D(latitude: Double(data.hotel?.latitude ?? 0.0), longitude: Double(data.hotel?.longitude ?? 0.0))
mapView.addAnnotation(annotation)
}
}
The longitudeDelta and latitudeDelta for a MKCoordinateSpan are measured in degrees. There are only 180 degrees of latitude from the north pole to the south pole, so using 200 for that parameter is not very sensible.
Since you want to show just the region of a city on the map, you can use this other initialiser that takes in distances in meters, if you know how big the cities that your app is handling usually are.
For example,
let coordinateRegion = MKCoordinateRegion(center: cityLocation, latitudinalMeters: 30000, longitudinalMeters: 30000)
If your cities have varying sizes, or you don't know how big they are, then another way is to calculate the range of latitudes and longitudes of the hotels, and use that to create an MKCoordinateSpan.
var minLat: CLLocationDegrees = 90
var maxLat: CLLocationDegrees = -90
var minLong: CLLocationDegrees = 180
var maxLong: CLLocationDegrees = -180
for data in hotelListData {
// ... you annotation code ...
guard let hotel = data.hotel else { continue }
if hotel.latitude < minLat { minLat = hotel.latitude }
if hotel.latitude > maxLat { maxLat = hotel.latitude }
if hotel.longitude < minLong { minLong = hotel.longitude }
if hotel.longitude > maxLong { maxLong = hotel.longitude }
}
let latRange = max(0.01, maxLat - minLat) // if the range is too small, make it at least 0.01
let longRange = max(0.01, maxLong - minLong)
let coordinateRegion = MKCoordinateRegion(
center: cityLocation,
span: MKCoordinateSpan(latitudeDelta: latRange, longitudeDelta: longRange)
I am having problems showing the annotations on the map. They only show when I move or drag the map.
I tried to follow tutorial on youtube and also one of the questions which is c sharp
Please can sone one help .. here is the code
Here I created a class for the annotation
class customPin: NSObject, MKAnnotation {
var coordinate: CLLocationCoordinate2D
var title: String?
var subtitle: String?
init(pinTitle:String, pinSubTitle:String, location:CLLocationCoordinate2D) {
self.title = pinTitle
self.subtitle = pinSubTitle
self.coordinate = location
}}
class ViewController: UIViewController, CLLocationManagerDelegate {
#IBOutlet weak var mapView: MKMapView!
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
mapView.register(CustomAnnotationView.self, forAnnotationViewWithReuseIdentifier: MKMapViewDefaultAnnotationViewReuseIdentifier)
self.locationManager.requestWhenInUseAuthorization()
//json show the list of the parks
pipiCanList()
//show location Barcelona
let location = CLLocationCoordinate2D(latitude: 41.3851 , longitude:2.1734)
let region = MKCoordinateRegion(center: location, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05))
self.mapView.setRegion(region, animated: true)
self.mapView.delegate = self
}
get the json information
func pipiCanList(){
let url = "http://bluewave.lk/Apps/pipiCan/Api/read.php";
let urlObj = URL(string:url);
URLSession.shared.dataTask(with: urlObj!) {(data, response, error) in
do{
let pipiCans = try JSONDecoder().decode([pipiCanDBList].self, from: data!)
for pipiCan in pipiCans{
let Latitude = (pipiCan.ParkLatitude! as NSString).doubleValue
let Longitude = (pipiCan.ParkLongitude! as NSString).doubleValue
let location = CLLocationCoordinate2D(latitude: Latitude, longitude: Longitude)
//add to
let pin = customPin(pinTitle: pipiCan.ParkName!, pinSubTitle: pipiCan.Area!, location: location)
self.mapView.addAnnotation(pin)
}
} catch{
print ("Error - cannot get list")
}
}.resume()
}
}
You need
DispatchQueue.main.async {
let pin = customPin(pinTitle: pipiCan.ParkName!, pinSubTitle: pipiCan.Area!, location: location)
self.mapView.addAnnotation(pin)
}
As URLSession.shared.dataTask callback is in a background thread and you should access UIKit elements like mapView in the main thread You can also do
self.mapView.showAnnotations(self.mapView.annotations, animated: true)
after the for loop to show all added annotations also keep in mind you set a region here
let location = CLLocationCoordinate2D(latitude: 41.3851 , longitude:2.1734)
let region = MKCoordinateRegion(center: location, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05))
that the response may be with far location values than the above region
I was integrating my app with a map, and when I declare a variable span with MKCoordinateSpan type, it gives me this error:
Cannot use instance member 'latDelta' within property initializer;
property initializers run before 'self' is available
Also when I write other types such as: CLLocationCoordinate2D or MKCoordinateRegion it still says me that the variable within the property initializer cannot be used.
I don't know what the problem is, any help would be appreciated!
Here's my code:
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet var map: MKMapView!
let latitude: CLLocationDegrees = 42.8
let longitude: CLLocationDegrees = 74.6
let latDelta: CLLocationDegrees = 0.05
let lonDelta: CLLocationDegrees = 0.05
let span: MKCoordinateSpan = MKCoordinateSpan(latitudeDelta: latDelta, longitudeDelta: lonDelta)
You need to initialize following in viewDidLoad()
let span: MKCoordinateSpan?;
And in viewDidLoad()
span = MKCoordinateSpan(latitudeDelta: latDelta, longitudeDelta: lonDelta);
That is not correct way to initialise values. but you can do that in any other class method. Check below code:
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet var map: MKMapView!
let latitude: CLLocationDegrees = 42.8
let longitude: CLLocationDegrees = 74.6
let latDelta: CLLocationDegrees = 0.05
let lonDelta: CLLocationDegrees = 0.05
//Declare it here
var span: MKCoordinateSpan?
override func viewDidLoad() {
super.viewDidLoad()
//Assign values here in method
span = MKCoordinateSpan(latitudeDelta: latDelta, longitudeDelta: lonDelta)
}
}

Problem:
I'm trying to make it so that it uses the user's location all the time and constantly checks to see if it is within 5 miles of the CLLocationCoordinate2D points I have set. If so, it sends a alert if the app is open or a notification if the app is closed.
Useful Information:
In my project I have 4 swift files:
Locations.swift holds the CLLocationCoordinate2D points.
Utilities.swift holds a simple alert.
UserLocation.swift retrieves and updates the user's location
GeoLocationViewController.swift monitors the locations
Note:
Some code may not be in the right place or relevant, I was looking at another project trying to extract relevant code from it to use in my project. Please tell me if you do catch a mistake.

First and foremost, change back startMonitoringGeotification(), regionWithGeotification(), and stopMonitoringGeotification() to take in a Geotification like the Ray Wenderlich tutorial. Make sure you have added the file Geotification.swift from his starter code to your project.
Also, make sure your Main.storyboard launches your ViewController. Without this step, none of your code will run.
1) redefine your Locations class more simply in Locations.swift:
import UIKit
import MapKit
class Locations {
static let locations:[String:CLLocationCoordinate2D] = [
"buddyrogers" : CLLocationCoordinate2D(latitude: 33.815995425565184, longitude: -116.44107442645873),
"diamond" : CLLocationCoordinate2D(latitude: 33.802168595307814, longitude: -116.45711048941041),
.
. // add your locations
.
]
}
}
like the #hungry-yeti suggested
2) You can define showSimpleAlertWithTitle() in your GeotificationViewController class. Try calling it in your ViewDidLoad() to test it. You can now delete Utilities.swift.
3) I think you can ignore/remove UserLocation.swift, this seems unnecessary
4) Put this code inside GeotificationViewController's ViewDidLoad:
let radius = CLLocationDistance(8046.72) // 5 miles in meters
for location in Locations.locations {
let g = Geotification(coordinate: location.1, radius: radius, identifier: location.0, note: "test", eventType: EventType.OnEntry)
startMonitoringGeotification(g)
}
5) I hope this helps and simplifies your code. Party on, reply here if you have any issues.
It looks like you're using the Ray Wenderlich tutorial. That's a good one, I found it very useful too.
First off, the unit for CLLocationDistance is meters so the code you have specifies a radius of 5 meters which won't be quite as useful as you may hope; a value of 8046.72 is closer to 5 miles.
Regarding the specific error, Locations is the class that you stuffed all CLLocationCoordinate2D values in, it certainly does not have any member called coordinate. If you're using the tutorial I'm thinking of you will need to load those coords into instances of the Geotification class.
Here is some untested code:
// Load the various coords into an array:
var locations:[(note:String, coords:CLLocationCoordinate2D)] = []
locations +=[(note: "arroyo", CLLocationCoordinate2D( latitude: 33.781327997137595, longitude: -116.46394436519012)]
locations +=[(note: "buddyrogers", CLLocationCoordinate2D( latitude: 33.78051204742721, longitude: -116.46362250010833)]
// ...
let radius = 8000 // ~5 miles rounded to nearest km
// Load the locations into geotifications:
for location in locations {
let geotification = Geotification(coordinate: location.cords, radius: radius, identifier: NSUUID().UUIDString, note: location.note, eventType: EventType.OnEnter)
startMonitoringGeotification(geotification)
}
Now bear in mind that there is a hard limit of 20 monitored regions per app, so if you have more than that you will need to dynamically determine the nearest 20 regions and then monitor those regions.
