swiftui-mapview
MKMapView in SwiftUI.
For iOS 14 and later, please use Apple's official Map view.
Install
Using Xcode, select File
-> Swift Packages
-> Add Package Dependency
and enter https://github.com/sgade/swiftui-mapview
.
Usage
In your view, add the map.
See the example project for how to integrate the map view.
import SwiftUIMapView
struct ContentView: View {
var body: some View {
MapView()
}
}
General
Map type
MapView(mapType: .standard)
User location
Showing the current user location
The current location can be shown on the map. By default, this is true
.
Note that the application requires permission to access the current user location.
See the documentation on MapView.showsUserLocation
for more information.
MapView(showsUserLocation: true)
Tracking the user's location
MapView(userTrackingMode: .follow)
Region
Setting the visible region center
The binding passed in for center
defines the visible region. Setting it to nil
will use the map's default region when loaded.
It is also updated when the visible region changes.
@State var center: CLLocationCoordinate2D?
MapView(center: self.$center)
Setting the visible region zoom
The binding passed in for zoom
defines the visible region span. A default zoom is used if you do not specify any value.
It is also updated when the visible region changes.
@State var zoom: MKCoordinateSpan
MapView(zoom: self.$zoom)
Annotations
Adding annotations
Annotations are represented as objects of a custom class that implements the MapViewAnnotation
protocol.
It might be helpful to sublcass from existing classes like MKPlacemark
.
let annotations: [MapViewAnnotation] = ...
MapView(annotation: self.annotations)
Selecting annotations
A list of selected annotations can be passed in via binding.
Selecting an annotations updates the binding, and the other way around.
@State var selectedAnnotations: [MapViewAnnotation] = []
MapView(selectedAnnotations: self.$selectedAnnotations)
