mapkit

There are lots of existing questions relating to this issue, but I have looked at as many of them as I could find and did not get an answer. I'm trying to perform an offline reverse geocoding lookup on iOS based on a latitude and longitude. I'd like to be able to provide a latitude and longitude, and be provided with the country in which that point lies. I can do this with Geonames (such as: http://api.geonames.org/countryCode?lat=45.03&lng=8.2&username=demo ), but I need a similar ability offline, without Internet functionality on the device. CLLocation does not provide offline services that

I need to show different annotation for different cat_ID on map. in this question i am including only two categories . let item = json["data"].arrayValue var count = 0 initMK() dispatch_async(dispatch_get_main_queue()) { while count < item.count{ let lat = item[count]["comp_lat"].stringValue let lng = item[count]["comp_lng"].stringValue if item[count]["ct_id"].stringValue == "783"{ self.state = "Jachthavens" let poi = MKPointAnnotation() let coordinates = CLLocationCoordinate2D(latitude: Double(lat)!, longitude: Double(lng)!) poi.coordinate = coordinates poi.title = item[count]["comp_name_pub"

In my swift application I'm using MapKit and I'm adding some annotations to the map. Currently, thanks to this question: Trying to get the span size in meters for an iOS MKCoordinateSpan I managed to create a functionality that centers my map on the annotation when user presses it. This is the code for it: let span = mapView.region.span let centerView = mapView.region.center let loc1 = CLLocation(latitude: centerView.latitude - span.latitudeDelta * 0.5, longitude: centerView.longitude) let loc2 = CLLocation(latitude: centerView.latitude + span.latitudeDelta * 0.5, longitude: centerView

I have the following code: MKMapRect mRect = self.mapView.visibleMapRect; MKMapPoint eastMapPoint = MKMapPointMake(MKMapRectGetMaxX(mRect), MKMapRectGetMaxY(mRect)/2); MKMapPoint northMapPoint = MKMapPointMake(MKMapRectGetMaxX(mRect)/2, 0); MKMapPoint southMapPoint = MKMapPointMake(MKMapRectGetMaxX(mRect)/2, MKMapRectGetMaxY(mRect)); MKMapPoint westMapPoint = MKMapPointMake(0, MKMapRectGetMaxY(mRect)/2); I am converting these to CLLocationCoordinate2D with MKCoordinateForMapPoint . For example: CLLocationCoordinate2D northCoords = MKCoordinateForMapPoint(northMapPoint); Along with northCoords

Background: I have created an application that allows users to submit an entry to an online database, and view other entries from that database. These entries contain geocodes for latitude and longitude which are used for positioning the annotations on the MapKit. Users can submit the location using either their current location or an address, which is then geocoded. Question: What is the proper or suggested method of handling annotations that fall on the exact same coordinates? I was thinking of checking if there are any duplicate geocodes in the XML file pulled from the database and creating

I have add a view with button as a subview to MKAnnotationView CCBigBubleViewController* buble = [[CCBigBubleViewController alloc] init]; [annotationView addSubView:buble.view]; It is shown perfectly, but the button does't respond to tapping. In your implementation of MKAnnotationView, override the hitTest method: - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { if (CGRectContainsPoint(_button.frame, point)) { return _button; } return [super hitTest:point withEvent:event]; } Your button will then receive touch events. your annotationView has probably not the right size. Out of

How can I convert an MKCircle's radius (in meters) into a value I can use to draw a circle using core graphics in an MKOverlayPathView subclass? In the following code the radius is hardcoded to 50 but I need it to reflect the radius of the MKCircle. For the position I use MKMapPointForCoordinate() to convert the MKCircle's coordinate to an MKMapPoint, then convert the MKMapPoint to a point using MKOverlayPathView's pointForMapPoint:. But how can I convert the MKCircle's radius into a relative distance? MKCircle *circle = [self circleForLocation:location]; CGPoint relativePoint = [self

I am using Firebase to get annotations on to mapView. This is done through the following: func getMarkers() { dbRef.observe(.value, with: { (snapshot) in for buildings in snapshot.children { let buildingsObject = Buildings (snapshot: buildings as! FIRDataSnapshot) let latDouble = Double(buildingsObject.latitude!) let lonDouble = Double(buildingsObject.longitude!) self.telephoneNumber = buildingsObject.number let annotation = myAnnotationView.init(title: buildingsObject.content!, coordinate: CLLocationCoordinate2D.init(latitude: latDouble!, longitude: lonDouble!), duration: buildingsObject
