import CoreLocationUI
struct MapUIView: View {
@StateObject private var ViewModel = ContentViewModal()
var body: some View {
ZStack(alignment: .bottom) {
Map(coordinateRegion: $ViewModel.region, showsUserLocation: true)
.ignoresSafeArea()
LocationButton(.currentLocation){
ViewModel.requestUserLocationForOnce()
}
.foregroundColor(.white)
.cornerRadius(8)
.padding()
}
}

MapUIView()

let locationManager = CLLocationManager()
override init() {
super.init()
locationManager.delegate = self
}
func requestUserLocationForOnce() {
locationManager.requestLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let latestLocation = locations.first else{
//show error
return
}
DispatchQueue.main.async {
self.region = MKCoordinateRegion(center: latestLocation.coordinate, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05))
}
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
}
Try this:
struct MapUIView: View {
@StateObject private var ViewModel = ContentViewModal()
var body: some View {
ZStack(alignment: .bottom) {
AreaMap(region: $ViewModel.region)
LocationButton(.currentLocation){
ViewModel.requestUserLocationForOnce()
}
.foregroundColor(.white)
.cornerRadius(8)
.padding()
}
}
}
struct MapUIView_Previews: PreviewProvider {
static var previews: some View {
MapUIView()
}
}
struct AreaMap: View {
@Binding var region: MKCoordinateRegion
var body: some View {
let binding = Binding(
get: { self.region },
set: { newValue in
DispatchQueue.main.async {
self.region = newValue
}
}
)
return Map(coordinateRegion: binding, showsUserLocation: true)
.ignoresSafeArea()
}
}
final class ContentViewModal: NSObject, ObservableObject, CLLocationManagerDelegate{
@Published var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 40, longitude: 120), span: MKCoordinateSpan(latitudeDelta: 100, longitudeDelta: 100))
let locationManager = CLLocationManager()
override init() {
super.init()
locationManager.delegate = self
}
func requestUserLocationForOnce() {
locationManager.requestLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let latestLocation = locations.first else {
//show error
return
}
self.region = MKCoordinateRegion(center: latestLocation.coordinate, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05))
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
}
