mapkit

I have a list of several hundred locations and only want to display an MKPinAnnotation for those locations currently on the screen. The screen starts with the user's current location with a 2 mile radius. Of course, the user can scroll, and zoom on the screen. Right now, I wait for a map update event, and then loop through my location list, and check the coordinates like this: -(void)mapViewDidFinishLoadingMap:(MKMapView *)mapView { CGPoint point; CLLocationCoordinate2D coordinate; . . . /* in location loop */ coordinate.latitude = [nextLocation getLatitude]; coordinate.longitude =

Hi I have an iPhone application using maps and locations. I would like the user to be able to press a button that gives turn by turn directions to that location. I understand that i am not allowed to do this in app, but i was wondering if anyone could tell me if it is possible to make a link to the native google maps application that will enter directions to the location from the users current location. If it is possible could you also tell me how? any help would be appreciated. Thanks Sure, it's possible - you've just got to tell the system to open a google maps link, with parameters for the

(Using iOS 5 and Xcode 4.2.) I've followed the instructions here: http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/LocationAwarenessPG/AnnotatingMaps/AnnotatingMaps.html#//apple_ref/doc/uid/TP40009497-CH6-SW15 and used the MKCircle and MKCircleView classes to add a circle overlay on my MKMapView . However what I actually want is an inverted circle overlay, like the left map in the sketch below (currently I have a circle overlay like the one on the right): For the inverted circle, the overlay should cover the entire map - apart from the visible circle. Is there an

On iOS11 the zPosition stopped working for the annotationView.layer. Every time the map region changes. No luck with original solution: layer.zPosition = X; No luck with bringViewToFront / SendViewToBack methods Xcode 8.3/9 UPDATE (SOLUTION thanks Elias Aalto): When creating MKAnnotationView: annotationView.layer.zPosition = 50; if (IS_OS_11_OR_LATER) { annotationView.layer.name = @"50"; [annotationView.layer addObserver:MeLikeSingleton forKeyPath:@"zPosition" options:0 context:NULL]; } In MeLikeSingleton or whatever observer object you have there: - (void)observeValueForKeyPath:(NSString *

i want display a point to point route inside my mapView, i use this code for create the route: - (IBAction)backToYourCar { MKPlacemark *sourcePlacemark = [[MKPlacemark alloc] initWithCoordinate:self.annotationForCar.coordinate addressDictionary:nil]; NSLog(@"coordiante : locationIniziale %f", sourcePlacemark.coordinate.latitude); MKMapItem *carPosition = [[MKMapItem alloc] initWithPlacemark:sourcePlacemark]; MKMapItem *actualPosition = [MKMapItem mapItemForCurrentLocation]; NSLog(@"coordiante : source %f, ActualPosition %f", carPosition.placemark.coordinate.latitude ,actualPosition.placemark

What I'm trying to do is pass a CLLocation to the function getPlacemarkFromLocation which then uses the passed CLLocation through reverseGeocodeLocation to set the CLPlacemark? that will be returned. I'm having issues creating the completionHandler closure in reverseGeocodeLocation , it's throwing a compiler error/crash: In Swift, CLGeocodeCompletionHandler is CLGeocodeCompletionHandler = (AnyObject[]!, NSError!) -> Void according to the documentation AnyObject[]! is supposed to contain CLPlacemark objects just like the Objective-C version. Here's my current code: class func
