mapkit

I'm starting a new app which uses the coreLocation and the mapkit frameworks. My problem is trying to get the current speed always returns me a negative value, i have take my iPhone with me to places with a good 3g signal and it doesn't matter, location.speed value is always -1. here is the code which matters: #define kRequiredAccuracy 1500.0 //meters #define kMaxAge 60.0 //seconds in the init method: self.locationManager=[[CLLocationManager alloc] init]; self.locationManager.delegate=self; self.locationManager.desiredAccuracy=kCLLocationAccuracyNearestTenMeters; then didUpdateToLocation: -

I need to replace the default annotation view with my custom annotation view. I need the do following things: Custom Annotation view with an image view embedded in it. A view below it which contains a label in it. For more clarification see the image: In the above image I need to place an image view in the white space which you can see in the image in circular form, next I also need to add a view which contains a label on which I can set any text like me, friends, etc... So, for this I searched number of questions on stack overflow but didn't got my answer. I don't want it on call out, I just

I am adding a callout view like this: func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!) { let calloutView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 120)) calloutView.backgroundColor = UIColor.purpleColor() calloutView.center = CGPointMake(CGRectGetWidth(view.bounds) / 2.0, 0.0) calloutView.layer.anchorPoint = CGPointMake(0.5, 1.0) calloutView.layer.masksToBounds = false calloutView.userInteractionEnabled = true let calloutViewTapRecognizer = UITapGestureRecognizer(target: self, action: "onCalloutViewTap") calloutView.addGestureRecognizer

I am annotating my map and setting an image just fine, but when I tap the annotation on the MapView, the image goes from my custom image back to the red pin. Why is this? - (MKAnnotationView *)mapView:(MKMapView *)newMapView viewForAnnotation:(id )newAnnotation { MKPinAnnotationView *annotation = [[MKPinAnnotationView alloc] initWithAnnotation:newAnnotation reuseIdentifier:@"currentloc"]; if (annotation == nil) { annotation = [[MKAnnotationView alloc] initWithAnnotation:newAnnotation reuseIdentifier:@"currentloc"]; } annotation.image = [UIImage imageNamed:@"anno.png"]; annotation

I need to figure out how to set up MKMapSnapshotterOptions to take a snapshot of aerial/satellite imagery associated with a polygonal region of the earth. Filling out the 'region', 'scale', 'size', and 'mapType' properties are trivial, as I have an MKPolygon to work with. The tricky part is in setting the 'camera' -- in my particular case, I am using MKMapSnapshotter independently of the MKMapView (in fact, not even on the main thread). However, I would prefer to orient the snapshot so that it fits the bounds of the polygon based on a non-zero heading -- that is, the area that I am taking a

I am working on an MKMapView based iPhone / iPad mapping app that overlays my own basic base map to provide for some limited functionality even when users are offline and can not reach Google's map tile server. This functionality is working - but I am having a hard time testing it after each new build because I can't find a way to flush / reset the iOS map tile cache. The iOS cache even survives a power-cycle and reboot of the iOS device. Anywhere I have zoomed into in the past renders with the tiles in memory from the prior test session. Is there a way to force iOS to flush its map cache?
