问题 I'm using MKDirections to draw a route from point A to point B, and I'm looking to put a MKPointAnnotation at specific distance from the starting point. For example, I have a MKMap with MKDirections drawn from LA to NY. I then would like to place a pin at the 10 mile marker for the route the user has decided to take. Any thoughts on how to find the lat/long, using the chosen route at a specific distance? Thanks. - (void)showDirections:(MKDirectionsResponse *)response { NSInteger iDistance = 0

问题 Any one knows what this exception means? /SourceCache/GoogleMobileMaps/GoogleMobileMaps-217.2/googlenav/mac/Loader.mm:194 Incorrect protocol version.

问题 As shown in the image below, there is a sudden jump in GPS coordinate while I keep track of user activity (walking, biking or driving). I do not know how to fix this problem even though I have already attempted multiple ways to solve, but as a reference I also posted my code below. In this image screenshot, I parked my car and walked to campus and came to my office, but it shows me that I went to Harvest Ln which is not right. -(void)locationManager:(CLLocationManager *)manager

问题 I have a project which is constrained to working with apple maps, corelocation and apple's mapkit -- 3rd party interfaces aren't allowed. I need to display a map view showing the user's current location (standard blue dot) and simultaneously place a pin on the road nearest the user's current location -- a 'snap to road' which is a best estimate of the user's nearest location. I know how to retrieve the user's current address and use the returned street name and address, but i don't know how

问题 I am trying to show a custom call out on top of pin in the map. It is required that I show an image with some text on top of pin as my call out. The code I wrote produces the following output. However, my desired output looks like this: How can I achieve my desired output ? Please note that the bubble is an image asset which has to be used, I know how to draw a bubble using CAShapeLayer but that does not accomplish what I want. Here is the code so far. // methods for Custom annotations func

问题 I have three MKPointAnnotation objects that are added in the exact same coordinates to an MKMapView and they are each given a unique title. MKPointAnnotation *a1 = [[MKPointAnnotation alloc] init]; a1.coordinate = CLLocationCoordinate2DMake(45.875684, -122.656254); a1.title = @"Title 1"; [self.mapView addAnnotation:a1]; MKPointAnnotation *a2 = [[MKPointAnnotation alloc] init]; a2.coordinate = CLLocationCoordinate2DMake(45.875684, -122.656254); a2.title = @"Title 2"; [self.mapView

问题 This web application is for Web and Android. I looked into others like Google, but they have limits. If you can use it can anyone point me to the documentation for it.

Here is my code: var tripspot:[tripSpot] = [ tripSpot( title: "一中商圈", coordinate: CLLocationCoordinate2DMake(24.149062, 120.684891), regionRadius: 300.0, location: "台中市北區一中街", type: "Food",cllocation:CLLocation(latitude: 24.181143, longitude: 120

问题 I have a custom placemark with title and subtitle. The subtitle is actually displaying the address of the dropped pin using the reverse geocoder. I have a button which has an action to drop the pin. This action gets the location coordinates of the user, and then calls [geocoder start] which gets the full address with Reverse Geocoder and generates the custom annotation and then calls [mapView addAnnotation:customPlacemark]. My problem is that using this sequence order, when there's no a WiFi

问题 I want to calculate the time require to complete path in between two location as like in Maps application in which if you will find the path in two location then it will also show you the estimated time required to complete it. Please suggest me regarding it. Thanks in advance. 回答1: If you use the Google Directions API you will be provided with a duration for the trip as part of the returned route. All you have to do is specify whether it should calculate for walking, bicycling or driving. 来源
