如何用swift中的坐标以编程方式打开地图App?

我想要打开我的地图应用程序的纬度和经度。我在HERE尝试了此代码。

    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)

}

此功能可成功打开地图,但不会显示任何图钉。它还显示了我不想要的用户位置。我只想在地图上找到所提供纬度和经度的图钉。

这段代码对我来说很好。

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)
    }
}

如果您只是想给用户提供行车路线,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])

如果您希望对地图中显示的信息进行精细控制,则上述MKMapItem方法效果很好。

否则,下面的代码也很有效,:

// 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该地点的自定义名称。相反,它会显示地址。

上面的代码还允许您从任何源坐标导航,如果您可以使用MKMapItem方法,我不知道。

答案 3 :(得分:22)

你可以调用MKMapItem传递项目的类函数,如果你想要传递两个以上的项目,它只适用于源/目的地的第一个和最后一个。

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])

这对我来说很有魅力

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)

答案 5 :(得分:3)

如果您想要的是简单的东西而无需导入任何框架,则只需创建一个URL:https://maps.apple.com/?ll=\(latitude),\(longitude)

类似于@ saniel-saidi的响应,但是此响应仅打开发送了位置的地图,而不是导航的东西

您可以使用以下代码在lat上显示PIN,长按Apple地图。

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])

更新为实用的Daniel Saidi answer。本示例仅用于告知目标坐标。地图将以用户当前位置为原点。

打开Apple Maps应用并在带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)
}
