【中文标题】使用我的 ios App iOS 9 Swift 2.2 中的路线打开 Apple Maps App【英文标题】:Open Apple Maps App With Directions from my ios App iOS 9 Swift 2.2 【发布时间】:2016-08-16 05:33:39 【问题描述】:我一直在寻找很多教程\帮助,但似乎没有找到任何,所以我再次来到这里.... 当我在我的应用中按下自定义 leftCalloutAccessory 时,我想打开 Apple 地图以获取路线并从用户当前位置导航到选定的 Pin
我已经设置了按钮,但无法使功能正常工作,所以请'如果有人可以指导我完成或帮助我使用代码,这将是一个救生员!谢谢
这是我的代码:
import UIKit
import MapKit
import CoreLocation
class MapViewController: UIViewController,MKMapViewDelegate, CLLocationManagerDelegate,UISearchBarDelegate
@IBOutlet weak var mapView: MKMapView!
let locationManager = CLLocationManager()
override func viewDidLoad()
super.viewDidLoad()
//==========RegionLocation : =========
// Init the zoom level
let coordinate:CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 31.30, longitude: 34.45)
let span = MKCoordinateSpanMake(125, 125)
let region = MKCoordinateRegionMake(coordinate, span)
self.mapView.setRegion(region, animated: true)
//====================================\\
override func didReceiveMemoryWarning()
super.didReceiveMemoryWarning()
//Dispose of resources that can be re created.
//Mark : Location
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.06, longitudeDelta: 0.06))
self.mapView.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
print("Errors: " + error.localizedDescription)
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView?
if annotation is MKUserLocation
return nil
let reuseID = "pin"
var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseID) as? MKPinAnnotationView
if(pinView == nil)
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseID)
pinView!.canShowCallout = true
pinView!.animatesDrop = true
pinView!.rightCalloutAccessoryView = UIButton(type: UIButtonType.DetailDisclosure) as UIButton
let smallSquare = CGSize(width: 30, height: 30)
let button = UIButton(frame: CGRect(origin: CGPointZero, size: smallSquare))
button.setBackgroundImage(UIImage(named: "Car"), forState: .Normal)
pinView?.leftCalloutAccessoryView = button
else
pinView!.annotation = annotation
return pinView
func mapView(MapView: MKMapView, annotationView: MKAnnotationView, calloutAccessoryControlTapped Control: UIControl)
if Control == annotationView.leftCalloutAccessoryView
【问题讨论】:
【参考方案1】:以下函数将打开 Apple Maps 应用程序,并显示从用户当前位置到坐标处指定目的地的行车路线。目的地名称显示在地图应用的 To: 字段中。
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)
您可以从代码中调用此函数,如下所示:
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)
【讨论】:
嘿,首先,在将代码添加到我的项目后,我会立即提示我将 requestDirections 错误修复到requestDirections(from: MapView.userLocation.location!.coordinate, to:annotationView.annotation!.coordinate)
,如果它很重要的话....其次,在应用程序本身中没有任何反应它不会打开苹果地图,但会在调试器中显示逐步说明
我的回答中的requestDirections
函数演示了如何检索两个坐标之间的方向。您如何呈现这些方向取决于您的应用程序。例如,如果要将方向显示为地图上的一条线,可以使用MKRoute
对象的polyline
属性添加折线注释。我希望这会有所帮助。
我明白了,感谢您的帮助,我还更新了我的问题,以便更准确地了解我在寻找什么。
我已更新我的答案以帮助您解决重命名和改写的问题。
嘿,它工作正常!但是它说它指向“未知位置”....有没有办法将其更改为注释标题或其他内容而不是“未知位置”?thx【参考方案2】:
像这样创建扩展:
extension CLLocation
func drive()
let placemark = MKPlacemark(coordinate: self.coordinate, addressDictionary: addressDictionary)
let launchOptions = [
MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving
]
MKMapItem.openMaps(with: [MKMapItem.forCurrentLocation(), MKMapItem(placemark: placemark)], launchOptions: launchOptions)
