如何使用 swift 中的坐标以编程方式打开地图应用程序？

Question

我有要在 map 应用程序中打开的纬度和经度。 我从HERE尝试了这段代码。

    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)

}

这个 function 成功打开地图，但它没有显示任何引脚。 它还显示了我不想要的用户位置。 我只想要 map 上提供的纬度和经度的引脚。

Answer 1

这段代码对我来说很好用。

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)
    
}

对于 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)
    }
}

斯威夫特 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

如果您只想为用户提供行车路线，这里是最简单形式的最新 Swift 语法：

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

您可以调用MKMapItem类函数在MKMapItem传递项目，如果您想传递两个以上的项目，它仅适当地使用第一个和最后一个作为源/目标。

斯威夫特 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]
)

或使用扩展名：

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

如果您希望对地图中显示的信息进行精细控制，则上述MKMapItem方法非常有效。

否则，下面的代码也很好用，：

// 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)!)

但是，上面的代码不允许您发送地点的自定义名称。 相反，它将显示地址。

上面的代码还可以让您从任何源坐标进行导航，我不知道您是否可以使用 MKMapItem 方法。

Answer 5

这对我来说是一种魅力

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

您可以使用以下代码在 lat 上显示 PIN，长在 Apple 地图中。

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

如果您想要的只是简单而无需导入任何框架的内容，您只需创建一个 URL： https://maps.apple.com/?ll=\\(latitude),\\(longitude) : https://maps.apple.com/?ll=\\(latitude),\\(longitude) \\( https://maps.apple.com/?ll=\\(latitude),\\(longitude)

类似于@saniel-saidi 响应，但此响应仅打开带有已发送位置的地图，而不是导航内容

Answer 8

更新实用的 Daniel Saidi答案。 此示例仅用于告知目的地坐标。 地图将获得用户当前位置作为原点。

let url = URL(string: "http://maps.apple.com/maps?saddr=&daddr=\(lat),\(lon)")
UIApplication.shared.open(url!)

Answer 10

打开 Apple Maps 应用程序并在具有自定义标题的自定义位置上显示图钉的最简单方法是：

let url = URL(string: "maps://?q=Title&ll=\(latitude),\(longitude)")!
if UIApplication.shared.canOpenURL(url) {
    UIApplication.shared.open(url)
}

Swift 5 解决方案：

以编程方式打开 Apple Map 或 Google Map

  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)
                }
            }
        }
    

不要忘记在 info.plist 中写这个

<key>LSApplicationQueriesSchemes</key>
    <array>
    <string>comgooglemaps</string>
    <string>comgooglemaps-x-callback</string>
    </array>
