How to open maps App programmatically with coordinates in swift? - ios

Question

I have latitude and longitude that I want to open into my map application. I tried this code from HERE.
func goToMap(){
var lat1 : NSString = self.venueLat
var lng1 : NSString = self.venueLng
var latitude:CLLocationDegrees = lat1.doubleValue
var longitude:CLLocationDegrees = lng1.doubleValue
var coordinate = CLLocationCoordinate2DMake(latitude, longitude)
var placemark : MKPlacemark = MKPlacemark(coordinate: coordinate, addressDictionary:nil)
var mapItem:MKMapItem = MKMapItem(placemark: placemark)
mapItem.name = "Target location"
let launchOptions:NSDictionary = NSDictionary(object: MKLaunchOptionsDirectionsModeDriving, forKey: MKLaunchOptionsDirectionsModeKey)
var currentLocationMapItem:MKMapItem = MKMapItem.mapItemForCurrentLocation()
MKMapItem.openMapsWithItems([currentLocationMapItem, mapItem], launchOptions: launchOptions)
}
This function successfully open maps but it doesn't show any pin. Also it shows user location which I don't want. I only want a pin on the map for the provided latitude and longitude.

Answer 1

This code is working fine for me.
func openMapForPlace() {
let lat1 : NSString = self.venueLat
let lng1 : NSString = self.venueLng
let latitude:CLLocationDegrees = lat1.doubleValue
let longitude:CLLocationDegrees = lng1.doubleValue
let regionDistance:CLLocationDistance = 10000
let coordinates = CLLocationCoordinate2DMake(latitude, longitude)
let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, regionDistance, regionDistance)
let options = [
MKLaunchOptionsMapCenterKey: NSValue(MKCoordinate: regionSpan.center),
MKLaunchOptionsMapSpanKey: NSValue(MKCoordinateSpan: regionSpan.span)
]
let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = "\(self.venueName)"
mapItem.openInMapsWithLaunchOptions(options)
}
For swift 3.0:
import UIKit
import MapKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
openMapForPlace()
}
func openMapForPlace() {
let latitude: CLLocationDegrees = 37.2
let longitude: CLLocationDegrees = 22.9
let regionDistance:CLLocationDistance = 10000
let coordinates = CLLocationCoordinate2DMake(latitude, longitude)
let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, regionDistance, regionDistance)
let options = [
MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: regionSpan.center),
MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: regionSpan.span)
]
let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = "Place Name"
mapItem.openInMaps(launchOptions: options)
}
}
Swift 5:
let latitude: CLLocationDegrees = Double(K.latitude)!
let longitude: CLLocationDegrees = Double(K.longitude)!
let regionDistance:CLLocationDistance = 10000
let coordinates = CLLocationCoordinate2DMake(latitude, longitude)
let regionSpan = MKCoordinateRegion(center: coordinates, latitudinalMeters: regionDistance, longitudinalMeters: regionDistance)
let options = [
MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: regionSpan.center),
MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: regionSpan.span)
]
let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = K.companyName
mapItem.openInMaps(launchOptions: options)

Answer 2

If you just want to give the user driving directions, here's the latest Swift syntax in its simplest form:
let coordinate = CLLocationCoordinate2DMake(theLatitude,theLongitude)
let mapItem = MKMapItem(placemark: MKPlacemark(coordinate: coordinate, addressDictionary:nil))
mapItem.name = "Target location"
mapItem.openInMaps(launchOptions: [MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving])

Answer 3

You could call class function of MKMapItem passing items there, it uses only first and last for source / destination appropriately, if you want pass more than two items.
Swift 5, 4
let source = MKMapItem(placemark: MKPlacemark(coordinate: CLLocationCoordinate2D(latitude: lat, longitude: lng)))
source.name = "Source"
let destination = MKMapItem(placemark: MKPlacemark(coordinate: CLLocationCoordinate2D(latitude: lat, longitude: lng)))
destination.name = "Destination"
MKMapItem.openMaps(
with: [source, destination],
launchOptions: [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
)
or using extension:
extension MKMapItem {
convenience init(coordinate: CLLocationCoordinate2D, name: String) {
self.init(placemark: .init(coordinate: coordinate))
self.name = name
}
}
let source = MKMapItem(coordinate: .init(latitude: lat, longitude: lng), name: "Source")
let destination = MKMapItem(coordinate: .init(latitude: lat, longitude: lng), name: "Destination")
MKMapItem.openMaps(
with: [source, destination],
launchOptions: [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
)

Answer 4

The MKMapItem approach above works great if you want granular control over the information that is displayed in Maps.
Otherwise, the code below works great as well, :
// Open and show coordinate
let url = "http://maps.apple.com/maps?saddr=\(coord.latitude),\(coord.longitude)"
UIApplication.shared.openURL(URL(string:url)!)
// Navigate from one coordinate to another
let url = "http://maps.apple.com/maps?saddr=\(from.latitude),\(from.longitude)&daddr=\(to.latitude),\(to.longitude)"
UIApplication.shared.openURL(URL(string:url)!)
However, the code above does not let you to send in a custom name of the place. Instead, it will show the address.
The code above also lets you navigate from any source coordinate, which I don't know if you can do with the MKMapItem approach.

Answer 5

This works as a charm for me
let coordinate = CLLocationCoordinate2DMake(theLatitude, theLongitude)
let region = MKCoordinateRegionMake(coordinate, MKCoordinateSpanMake(0.01, 0.02))
let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
let options = [
MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: region.center),
MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: region.span)]
mapItem.name = theLocationName
mapItem.openInMaps(launchOptions: options)

Answer 6

You can use below code to show PIN on lat, long in to Apple map.
let coordinates = CLLocationCoordinate2DMake(-37.848854,144.990295)
let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, 1000, 1000)
let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = “Desired place”
mapItem.openInMaps(launchOptions:[
MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: regionSpan.center)
] as [String : Any])

Answer 7

If what you want is something simple without importing any framework you can just create a URL: https://maps.apple.com/?ll=\(latitude),\(longitude)
Is similar to #saniel-saidi response but this one opens just the map with location sent, not the navigation thing

Answer 8

Update to the practical Daniel Saidi answer. This example is for telling only the destination coordinates. Maps will get as origin the user current position.
let url = URL(string: "http://maps.apple.com/maps?saddr=&daddr=\(lat),\(lon)")
UIApplication.shared.open(url!)

Answer 10

The simplest way to open the Apple Maps app and show a pin on the custom location with a custom title is that:
let url = URL(string: "maps://?q=Title&ll=\(latitude),\(longitude)")!
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url)
}

Swift 5 Solution:
Open Apple Map OR Google Map Programmatically
let actionSheet = UIAlertController(title: "Open Location", message: "Choose an app to open direction", preferredStyle: .actionSheet)
actionSheet.addAction(UIAlertAction(title: "Google Maps", style: .default, handler: { _ in
// Pass the coordinate inside this URL
self.openGoogleMap()
}))
actionSheet.addAction(UIAlertAction(title: "Apple Maps", style: .default, handler: { _ in
// Pass the coordinate that you want here
self.openAppleMap()
}))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
self.present(actionSheet, animated: true, completion: nil)
//Function defination here
func openAppleMap(){
guard let lat = bookingData.gpsLatitude, let latDouble = Double(lat) else {return }
guard let long = bookingData.gpsLongitude, let longDouble = Double(long) else {return }
let coordinate = CLLocationCoordinate2DMake(latDouble,longDouble)
let mapItem = MKMapItem(placemark: MKPlacemark(coordinate: coordinate, addressDictionary: nil))
mapItem.name = "Destination"
mapItem.openInMaps(launchOptions: [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving])
}
func openGoogleMap() {
guard let lat = bookingData.gpsLatitude, let latDouble = Double(lat) else {return }
guard let long = bookingData.gpsLongitude, let longDouble = Double(long) else {return }
if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) { //if phone has an app
if let url = URL(string: "comgooglemaps-x-callback://?saddr=&daddr=\(latDouble),\(longDouble)&directionsmode=driving") {
UIApplication.shared.open(url, options: [:])
}}
else {
//Open in browser
if let urlDestination = URL.init(string: "https://www.google.co.in/maps/dir/?saddr=&daddr=\(latDouble),\(longDouble)&directionsmode=driving") {
UIApplication.shared.open(urlDestination)
}
}
}
Don't forget to write this in info.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>comgooglemaps</string>
<string>comgooglemaps-x-callback</string>
</array>
