问题 I have implemented Web Map Service in the MKMapView by subclassing the MKTileOverlay & rendering it using MKTileOverlayRenderer . It works fine and displays the custom map properly. When I call method like mapView.addOverlay(polyLine) to add Polyline or Polygon. The WMS overlay gets replaced with the Apple Maps overly. // Set up the overlay and adds it to MKMapView. func setupTileRenderer() { let wmsURL = formTemplate?.wmsURL let overlay = WMSTileOverlay(urlTemplate: wmsURL) overlay

问题 I am having problems with a map view in my app. I have created a button that when clicked should show users location on the map, but nothing happens (no error messages occur). I believe the issue may lie in the way I've written the delegates. The code from the relevant .h and .m files is below: mapViewController.h #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import <CoreLocation/CoreLocation.h> @interface mapViewController : UIViewController { MKMapView *mapview; } @property (nonatomic,

问题 So from the multiple answers I see on here this is how to center and zoom on user location when the app loads and it works great. -(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation{ NSLog(@"Did update user location"); MKCoordinateRegion mapRegion; mapRegion.center = mapView.userLocation.coordinate; mapRegion.span.latitudeDelta = 0.2; mapRegion.span.longitudeDelta = 0.2; [map setRegion:mapRegion animated: YES]; } But when you start playing with the map

问题 I have a mapview controller which shows pins from an array of business objects I have created (each business has a method to get the title and subtitle of the pin). I have added a disclosure button to each pin annotation which works correctly, but I am not sure how to pass a variable to the detail view which is to be loaded from the disclosure button, and show all the details for that particular business. I add my businesses to the array like this (in viewWillAppear)... // fetch model data

Closed last year . I have created a table in database named UserJourneyLocation which consist of columns LocationID, Latitude, Longitude. The latitude and longitude values are stored in SQLite database. I want to fetch these latitude and longitude values that are there and display them on map and draw

问题 Is it possible to change the radius of the blue pulsing circle around current user's location in MapKit? I have an application which looks around current location for points of interest within a certain radius. I'd like to show this circle to the user without having to completely provide a new annotation for current user location. Any ideas? 回答1: This radius signifies the GPS's inaccuracy. I don't think you can override its behaviour. 回答2: Take a look at the Mapbox iOS SDK, which is open
