我正在使用Mapbox创建我的应用。当我点击一个按钮时,我希望它标记我当前的位置,并像现在一样添加一个标记。然后我想要点击这个标记并让它显示当前的位置信息,例如标记点的地址。
现在我所拥有的只是......
我想说明我使用的是Xcode 9.1和Swift 4.感谢您提前提供所有反馈。
目前swift文件看起来像......
import Foundation
import UIKit
import CoreLocation
import Mapbox
import MapKit
import MapboxGeocoder
class SecondViewController: UIViewController, CLLocationManagerDelegate, MGLMapViewDelegate, UITextFieldDelegate {
let geocoder = Geocoder.shared
let dismissesAutomatically: Bool = false
let isAnchoredToAnnotation: Bool = true
weak var delegate: MGLCalloutViewDelegate?
let tipHeight: CGFloat = 10.0
let tipWidth: CGFloat = 20.0
@IBOutlet var mapView: MGLMapView!
let manager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func markStuff(_ sender: Any) {
}
@IBAction func refLocation(_ sender: Any) {
manager.startUpdatingLocation()
}
func mapView(_ mapView: MGLMapView, annotationCanShowCallout annotation: MGLAnnotation) -> Bool {
return true
}
func mapView(_ mapView: MGLMapView, viewFor annotation: MGLAnnotation) -> MGLAnnotationView? {
return nil
}
func mapView(_ mapView: MGLMapView, tapOnCalloutFor annotation: MGLAnnotation)
{
print("tap on callout")
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations[0]
let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
mapView.setCenter(center, zoomLevel: 10, animated: true)
let annotation = MGLPointAnnotation()
annotation.coordinate = location.coordinate
mapView.selectAnnotation(annotation, animated: true)
annotation.title = "Testing"
annotation.subtitle = "\(annotation.coordinate.latitude), \(annotation.coordinate.longitude)"
self.mapView.addAnnotation(annotation)
manager.stopUpdatingLocation()
答案 0 :(得分:1)
您可以创建MGLUserLocationAnnotationView的子类,然后将其用作YourLocationAnnotationView()
注释的视图。
例如,如果您的自定义子类名为func mapView(_ mapView: MGLMapView, viewFor annotation: MGLAnnotation) -> MGLAnnotationView? {This custom view is created below.
if annotation is MGLUserLocation && mapView.userLocation != nil {
return YourLocationAnnotationView()
}
return nil
}
}
,则可以执行以下操作:
env.sh
