I'm rendering some content in a layer that sits on top of my MKMapView . The whole thing works great with the exception of rotation. When a user rotates the map I need to be able to rotate what I'm rendering in my own layer. The standard answer I found is to use: NSLog(@"heading: %f", self.mapView.camera.heading"); The issue with this is that the content of the heading variable only updates when the pinch/rotate gesture is ending, not during the gesture. I need much more frequent updates. There is no heading property on the mapView itself. I thought maybe using KVO like such: // Somewhere in

In my app.I have a one textfield and one search button.when it user click on search button after fill up the address on textfield my app shows the result and place a pin on mapview. I am using google maps api for it.

I'm using the J4n0 Callout code ( github ) to implement a custom annotation in MapKit. It was working just fine on iOS5. But on iOS6 I have 2 problems: Annotations are displayed over the AnnotationView (see picture 1). The first Click on an Annotation opens the AnnotationView just fine, but the second click opens an annotation with a bad size (see picture 2). Does anyone using this library have some similar problem/solution? I can give some code if needed! Sibear If annotations are displayed over the AnnotationView try to code: - (void)didMoveToSuperview { [super didMoveToSuperview]; [self

I have a mapView with annotations displaying titles and subtitles. The subtitles are sometimes longer than the width of the annotation, so I am wondering if i can make them multiline? It's coded like this so far: func annotate(newCoordinate, title: String, subtitle: String) { let annotation = MKPointAnnotation() annotation.coordinate = newCoordinate annotation.title = title annotation.subtitle = subtitle self.map.addAnnotation(annotation) } Then i have a few options set in func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {...} which are not

I am trying to map a JSON array using the MapKit. I can get a single point on the map with the code below, but I have dozens of pins I need to mark, and I have a JSON array prepared. My code for a single point is below. In my .h file: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewController : UIViewController { MKMapView *mapView; NSData *data; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @end In my .m file: NSData *data = @"[{"id":"1","name":"Jiffy Lube","lat":"21.306","lon":"-157.861"}, {"id":"2","name":"Bills Oil","lat":"21.301","lon":"-157.863"},{"id":
