Your code seems fine to me. Nothing wrong with the calculous. You don’t specify how far off your results are, but you might try tweaking your radian/degrees converters to this: double DegreesToRadians(double degrees) {return degrees * M_PI / 180.0;}; double RadiansToDegrees(double radians) {return radians * 180.0/M_PI;}; If you are getting negative bearings, add 2*M_PI to … Read more
The link posted by Jim is now dead, but i was able to find the code (which I had bookmarked somewhere). Hope this helps. – (void)zoomToFitMapAnnotations:(MKMapView *)mapView { if ([mapView.annotations count] == 0) return; CLLocationCoordinate2D topLeftCoord; topLeftCoord.latitude = -90; topLeftCoord.longitude = 180; CLLocationCoordinate2D bottomRightCoord; bottomRightCoord.latitude = 90; bottomRightCoord.longitude = -180; for(id<MKAnnotation> annotation in mapView.annotations) { … Read more
Here’s the official Apple way: // Check for iOS 6 Class mapItemClass = [MKMapItem class]; if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) { // Create an MKMapItem to pass to the Maps app CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(16.775, -3.009); MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:coordinate addressDictionary:nil]; MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark]; [mapItem setName:@”My Place”]; // Pass the … Read more
The easiest technique is to just shift the map down, say 40% from where the coordinate would be, taking advantage of the span of the region of the MKMapView. If you don’t need actual pixels, but just need it to move down so that the CLLocationCoordinate2D in question is near the top of the map … Read more
You are doing it right.You just need to have these methods implemented for adding button along with title and subtitle iOS 8 and Xcode 6 import UIKit import MapKit import CoreLocation class MapKitViewController: UIViewController, MKMapViewDelegate { let locationManager = CLLocationManager() @IBOutlet weak var nmapView: MKMapView! override func viewDidLoad() { super.viewDidLoad() locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation() let location = … Read more

One problem with the code above by Anna Karenina is that it doesn’t deal with when you add annotations below where the user is looking at the moment. Those annotations will float in mid-air before dropping because they are moved into the user’s visible map rect. Another is that it also drops the user location … Read more
Okay I officially answered my own question but since I didn’t find it anywhere before I’ll post the answer here: //To calculate the search bounds… //First we need to calculate the corners of the map so we get the points CGPoint nePoint = CGPointMake(self.mapView.bounds.origin.x + mapView.bounds.size.width, mapView.bounds.origin.y); CGPoint swPoint = CGPointMake((self.mapView.bounds.origin.x), (mapView.bounds.origin.y + mapView.bounds.size.height)); //Then … Read more
I got it working. I’ve posted my code below to help anyone else having issues. Here is my full code to get the MapKit Map View working in iOS 8. In your AppName-Info.plist Add a new row with the key name being: NSLocationWhenInUseUsageDescription Or NSLocationAlwaysUsageDescription With the value being a string of the message that … Read more
some more 😉 And the original ones : And the code: – (MKAnnotationView*)mapView:(MKMapView*)mapView viewForAnnotation:(id <MKAnnotation>)annotation { MKPinAnnotationView* anView =[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@”test”]; anView.pinColor=MKPinAnnotationColorPurple; UIImage* image = nil; // 2.0 is for retina. Use 3.0 for iPhone6+, 1.0 for “classic” res. UIGraphicsBeginImageContextWithOptions(anView.frame.size, NO, 2.0); [anView.layer renderInContext: UIGraphicsGetCurrentContext()]; image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); NSData* imgData = UIImagePNGRepresentation(image); NSString* … Read more
