How to Open Maps App Programmatically with Coordinates in Swift

How to open maps App programmatically with coordinates in swift?

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)

Open Apple Maps programmatically

You can just pass your address information as URL parameters in the URL with which you open the maps app. Say you wanted the maps app to open centered on The White House.

UIApplication.sharedApplication().openURL(NSURL(string: "http://maps.apple.com/?address=1600,PennsylvaniaAve.,20500")!)

The Maps app opens with the ugly query string in the search field but it shows the right location. Note that the city and state are absent from the search query, it's just the street address and the zip.

A potentially better approach, depending on your needs, would be to get the CLLocation of the address info you have using CLGeocoder.

let geocoder = CLGeocoder()
let str = "1600 Pennsylvania Ave. 20500" // A string of the address info you already have
geocoder.geocodeAddressString(str) { (placemarksOptional, error) -> Void in
  if let placemarks = placemarksOptional {
    print("placemark| \(placemarks.first)")
    if let location = placemarks.first?.location {
      let query = "?ll=\(location.coordinate.latitude),\(location.coordinate.longitude)"
      let path = "http://maps.apple.com/" + query
      if let url = NSURL(string: path) {
        UIApplication.sharedApplication().openURL(url)
      } else {
        // Could not construct url. Handle error.
      }
    } else {
      // Could not get a location from the geocode request. Handle error.
    }
  } else {
    // Didn't get any placemarks. Handle error.
  }
}

Open map in a given address using MapKit and Swift

You need to use the Geocoding service to convert an address to the corresponding geolocation.

For instance, add this function to your toolkit:

func coordinates(forAddress address: String, completion: @escaping (CLLocationCoordinate2D?) -> Void) {
    let geocoder = CLGeocoder()
    geocoder.geocodeAddressString(address) { 
        (placemarks, error) in
        guard error == nil else {
            print("Geocoding error: \(error!)")
            completion(nil)
            return
        }
        completion(placemarks.first?.location?.coordinate)
    }
}

and then use it like this:

coordinates(forAddress: "YOUR ADDRESS") { 
    (location) in
    guard let location = location else {
        // Handle error here.
        return
    }
    openMapForPlace(lat: location.latitude, long: location.longitude) 
}

Open Apple Maps App With Directions from my ios App iOS 9 Swift 2.2

The following function will open the Apple Maps app and present driving directions from the user's current location to a named destination at a coordinate. The destination name is displayed in the To: field of the Maps app.

func openMapsAppWithDirections(to coordinate: CLLocationCoordinate2D, destinationName name: String) {
  let options = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
  let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: nil)
  let mapItem = MKMapItem(placemark: placemark)
  mapItem.name = name // Provide the name of the destination in the To: field
  mapItem.openInMapsWithLaunchOptions(options)
}

You can call this function from your code as follows:

func mapView(MapView: MKMapView, annotationView: MKAnnotationView, calloutAccessoryControlTapped Control: UIControl) {

  if Control == annotationView.leftCalloutAccessoryView {
    if let annotation = annotationView.annotation {
      // Unwrap the double-optional annotation.title property or
      // name the destination "Unknown" if the annotation has no title
      let destinationName = (annotation.title ?? nil) ?? "Unknown"
      openMapsAppWithDirections(to: annotation.coordinate, destinationName: destinationName)
    }
  }

}

Is It Possible To Open Google Maps By PlaceId in iOS?

Yes you can open Google Maps from your iOS App. There is a documentation available for opening Google Maps Via iOS App.

An example would be:

UIApplication.shared.openURL(URL(string:"https://www.google.com/maps/search/?api=1&query=47.5951518,-122.3316393&query_place_id=ChIJKxjxuaNqkFQR3CK6O1HNNqY")!)

For this to work, there should be Google Maps App installed on the device. Though if you have the Placeid and Google SDK installed on your APP then you must have it's Latitude and Longitude. You can open default Maps to do this task for you. This SO Post is a great place to start!

Open an Alert asking to choose App to open map with

Swift 5+ solution based on previous answers, this one shows a selector between Apple Maps, Google Maps, Waze and City Mapper. It also allows for some optional location title (for those apps that support it) and presents the alert only if there are more than 1 option (it opens automatically if only 1, or does nothing if none).

func openMaps(latitude: Double, longitude: Double, title: String?) {
    let application = UIApplication.shared
    let coordinate = "\(latitude),\(longitude)"
    let encodedTitle = title?.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) ?? ""
    let handlers = [
        ("Apple Maps", "http://maps.apple.com/?q=\(encodedTitle)&ll=\(coordinate)"),
        ("Google Maps", "comgooglemaps://?q=\(coordinate)"),
        ("Waze", "waze://?ll=\(coordinate)"),
        ("Citymapper", "citymapper://directions?endcoord=\(coordinate)&endname=\(encodedTitle)")
    ]
        .compactMap { (name, address) in URL(string: address).map { (name, $0) } }
        .filter { (_, url) in application.canOpenURL(url) }

    guard handlers.count > 1 else {
        if let (_, url) = handlers.first {
            application.open(url, options: [:])
        }
        return
    }
    let alert = UIAlertController(title: R.string.localizable.select_map_app(), message: nil, preferredStyle: .actionSheet)
    handlers.forEach { (name, url) in
        alert.addAction(UIAlertAction(title: name, style: .default) { _ in
            application.open(url, options: [:])
        })
    }
    alert.addAction(UIAlertAction(title: R.string.localizable.cancel(), style: .cancel, handler: nil))
    contextProvider.currentViewController.present(alert, animated: true, completion: nil)
}

Note this solution uses R.swift for string localization but you can replace those with NSLocalizedString normally, and it uses a contextProvider.currentViewController to get the presented UIViewController, but you can replace it with self if you are calling this in a view controller already.

As usual, you need to also add the following to your app Info.plist:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>citymapper</string>
    <string>comgooglemaps</string>
    <string>waze</string>
</array>

Opens apple maps app from ios app with directions

Here is code to open Map app with directions:

Objective-C Code

NSString* directionsURL = [NSString stringWithFormat:@"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",self.mapView.userLocation.coordinate.latitude, self.mapView.userLocation.coordinate.longitude, mapPoint.coordinate.latitude, mapPoint.coordinate.longitude];
if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: directionsURL] options:@{} completionHandler:^(BOOL success) {}];
} else {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: directionsURL]];
}

with the mapPoint is where you want to direction to.

Swift3 or later

let directionsURL = "http://maps.apple.com/?saddr=35.6813023,139.7640529&daddr=35.4657901,139.6201192"
guard let url = URL(string: directionsURL) else {
    return
}
if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    UIApplication.shared.openURL(url)
}

Note that saddr, daddr is urlencoded string of location name or location coordinate (about encode URL look at here).

directionsURL example:

// directions with location coordinate
"http://maps.apple.com/?saddr=35.6813023,139.7640529&daddr=35.4657901,139.6201192"
// or directions with location name
"http://maps.apple.com/?saddr=Tokyo&daddr=Yokohama"
// or directions from current location to destination location
"http://maps.apple.com/?saddr=Current%20Location&daddr=Yokohama"

How to open Google Maps to show route using Swift

OK I found the answer myself.

If you want to show directions from the user's current location, leave the field saddr blank and in the field daddr you can enter the destination coordinates.

This is how I did it

if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"comgooglemaps://")!)) {
            UIApplication.sharedApplication().openURL(NSURL(string:
                "comgooglemaps://?saddr=&daddr=\(place.latitude),\(place.longitude)&directionsmode=driving")!)

        } else {
            NSLog("Can't use comgooglemaps://");
        }
    }

How to open google maps app with a dropped pin ? - Swift

q: The query string for your search.

It creates a marker in given coordinates. Try this

if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {
        UIApplication.shared.open(URL(string:"comgooglemaps://?center=\(self.location.coordinate.latitude),\(self.location.coordinate.longitude)&zoom=14&views=traffic&q=\(self.location.coordinate.latitude),\(self.location.coordinate.longitude)")!, options: [:], completionHandler: nil)
    } else {
        print("Can't use comgooglemaps://")
    }
}
