mapkit

I want to update the images of some of my annotations on a mapview every 5 seconds, however I dont' want to remove and re-add them to the map as this causes them to 'flash' or refresh, (ie disapear then reappear). I want it to be seamless. I've tried the following: //get the current icon UserAnnotation *annotation = [self GetUserIconWithDeviceId:deviceId]; //make a new annotation for it UserAnnotation *newAnnotation = [[UserAnnotation alloc] initWithCoordinate: userCoordinates addressDictionary:nil]; newAnnotation.title = name; newAnnotation.userDeviceId = deviceId; NSInteger ageIndicator = [

I am attempting to draw a nice MKPolyline on an MKPolylineView . Everything is going great so far - the polyline draws just as I want it to and when I want it to using the following code: [[self map] addOverlay:routeLine]; And this method to tell the app how to draw it: - (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay { MKOverlayView* overlayView = nil; self.routeLineView = [[MKPolylineView alloc] initWithPolyline:[self routeLine]]; [[self routeLineView] setFillColor:[UIColor colorWithRed:167/255.0f green:210/255.0f blue:244/255.0f alpha:1.0]]; [[self

I would like to know if someone has got documentation about the Google Maps API, I'm only looking for the traffic live information I would like to implement it on my iOS application. Does such an API exist? I don't think Google offers a standlone traffic API as of now. However there are a couple options. Render the Google Maps element in a WebView and use the Google JavaScript API to enable the traffic layer. The downside of this approach is that the UX likely wont be as nice as native programming. The upside is less coding. http://code.google.com/apis/maps/documentation/javascript/ http:/

How is a 1000ft or 1/2 mile distance determined with mapkit? Either a radius from some pin or the distance between two pins. For example, I center the map on pin A. Pins B, C, and D are also on the map at various distances from pin A. B and C are within 1/2 mile from A but D is 1 mile away. I'd like to know that B and C are within 1/2 mile from A. How can I calculate that? Since you've stated that the two different points are "pins", I'm going to assume you're using MKPinAnnotationView (or some other annotation view). If not, you're going to have to get the location some other way. If you have

I have very simple View Controller to demonstrate this strange rendering behavior of MKPolyline. Nothing special just normal api calls. import UIKit import MapKit class ViewController: UIViewController, MKMapViewDelegate { @IBOutlet weak var map: MKMapView! override func viewDidLoad() { super.viewDidLoad() map.delegate = self } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) let p1 = CLLocationCoordinate2D(latitude: 51, longitude: 13) var coords = [ p1, CLLocationCoordinate2D(latitude: 51.1, longitude: 13), CLLocationCoordinate2D(latitude: 51.2, longitude: 13),

I am trying to show current location of user by setting the property of MKMapView i.e setShowsUserLocation to YES . As by default an arrow appears on the top left of iPhone screen when the application starts updating the user location.But after showing the current location the arrow should disappear but its still present as long as the app is running which would mean the app is still updating the location in the background? so how can i stop updating the current location? i have implemented the delegate which gets called up immediately.. Cyril Godefroy If the map is visible and has

I am developing a custom pins in a MapView in my iPhone app. Here is the code: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { static NSString *AnnotationViewID = @"annotationViewID"; MKAnnotationView *annotationView = (MKAnnotationView *)[myMapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID]; if (annotationView == nil) { annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease]; } if ([[annotation title] isEqualToString:NSLocalizedString(@"Current Location",@""

I put the personal image instead of the traditional red pin. When I open the map to display the pin, the image cover the entire map. Is there a maximum size of the pin image or how do I integrate something in the code to fit the size standard classic pin? func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? { if annotation is MKUserLocation { return nil } let annotationIdentifier = "SomeCustomIdentifier" // use something unique that functionally identifies the type of pin var annotationView: MKAnnotationView! = mapView
