Crash at MKMapItem.placemark.coordinate
Your problem is that you are adding an MKAnnotationView to the map rather than an MKAnnotation - You either need to add an instance of a class that implements the MKAnnotation protocol or an MKPointAnnotation
iOS Custom Annotation: A view below the annotation pin

MKAnnotation Left / Right Accessory View Misplacement
This seems to be a bug which can be workarounded in different ways. The rightCalloutAccessoryView vertical alignment can be fixed by simply setting the autoresizingMask as follows: UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeInfoLight]; rightButton.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleTopMargin; annotationView.rightCalloutAccessoryView = rightButton; The same trick does not work with the leftCalloutAccessoryView which...
Swift location comes back nil
The location property of CLLocationManager is declared as: @NSCopying var location: CLLocation! { get } and thus your let location could be filled with a nil value. Perhaps this declaration changed recently as Apple scrubs their interfaces related to optionals. You'll need to bind your latitude and longitude while respecting...

Try this: for step in self.route!.steps as [MKRouteStep] { otherwise it treats step as AnyObject (which doesn't have a polyline property defined so you get that compiler error).

Xcode Error: Outlets cannot be connected to repeating content
ios,xcode,uitableview,swift,mapkit
This message only occurs if you connect it to the view controller. As I have already commented, you probably did not delete the first connection outlet you've made to your view controller. Even if you delete the IBOutlet code from your view controller you still need to right click it...
How to draw UIBezierPath overlay on MKMapView?
ios,mkmapview,mapkit,mkoverlay
According to Anna's answer you should use [self pointForMapPoint:points[i]] instead of points[i] - (void)createPath { MKPolyline *line = (id)self.overlay; MKMapPoint *points = line.points; NSUInteger pointCount = line.pointCount; CGMutablePathRef path = CGPathCreateMutable(); CGPoint point = [self pointForMapPoint:points[0]]; CGPathMoveToPoint(path, NULL, point.x, point.y); for (int i = 1; i < pointCount; i++) {...
addAnnotation not updating Map?
Anna was on the right path. I was creating a new instance of the DetailViewController. I was able to solve it by adding @property (strong, nonatomic) DetailViewController *detailViewController; to the MasterViewController.h. And then just calling [self.detailViewController addPins:woX ycoord:woY desc:cellView]; in MasterViewController.m...
MKDirections multiple locations xcode 6.2 Mapkit

How can i know which geopoint(lat/lng) belong to which country without reverse geocoding?
ios,google-maps,geolocation,mapkit,reverse-geocoding
A solution is to change the way your data is structured. When a user checks in, besides storing a coordinate, store data such as the city, state, or country associated with the coordinate. Doing it this way, each user would reverse geocode a coordinate before checking in.
Swift - Getting address from coordinates
Your assumption is wrong. You can generate a request for driving directions using lat/long coordinates just as easily as using addresses. Here's what you do: Get the MKMapItem for the user-selected pin Create a second MKMapItem for the user's current location using the MKMapItem method mapItemForCurrentLocation(). Call the MKMapItem class...
Adding accessory button on user location callout
ios,swift,mapkit,mkuserlocation
You want to put an accessory button on the callout of the blue dot (user location). In the viewForAnnotation delegate method, you do have code that creates an annotation view and sets the rightCalloutAccessoryView but at the top of the method there is this code: func mapView(Mapa: MKMapView!, viewForAnnotation annotation:...
iOS search api for Maps
MKLocalSearch with MKLocalSearchRequest is exactly what you are looking for. A basic search can be done as follows: MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.naturalLanguageQuery = @"some address"; MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:request]; [localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) { // do stuff with the response }]; This should put...
