신속하게 좌표를 사용하여 프로그래밍 방식으로지도 앱을 여는 방법은 무엇입니까?

신속하게 좌표를 사용하여 프로그래밍 방식으로지도 앱을 여는 방법은 무엇입니까?

---

지도 응용 프로그램에서 열고 싶은 위도와 경도가 있습니다. 나는 여기 에서이 코드를 시도했다 .

    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)

}

이 기능은지도를 성공적으로 열었지만 핀이 표시되지 않습니다. 또한 내가 원하지 않는 사용자 위치를 보여줍니다. 제공된 위도와 경도에 대한 핀만지도에 표시하고 싶습니다.

이 코드는 저에게 잘 작동합니다.

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)

}

신속한 3.0의 경우 :

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)
    }
}

사용자에게 운전 경로를 제공하려는 경우 가장 간단한 형식의 최신 Swift 구문은 다음과 같습니다.

let coordinate = CLLocationCoordinate2DMake(theLatitude,theLongitude)
let mapItem = MKMapItem(placemark: MKPlacemark(coordinate: coordinate, addressDictionary:nil))
mapItem.name = "Target location"
mapItem.openInMaps(launchOptions: [MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving])

MKMapItem위 의 접근 방식은지도에 표시되는 정보를 세부적으로 제어하려는 경우 유용합니다.

그렇지 않으면 아래 코드도 잘 작동합니다.

// 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)!)

그러나 위의 코드에서는 장소의 사용자 지정 이름을 보낼 수 없습니다. 대신 주소가 표시됩니다.

The code above also lets you navigate from any source coordinate, which I don't know if you can do with the MKMapItem approach.

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])

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)

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])
