mkannotation

In my app I am showing location of some other person by getting their location (latitude and longitude) from server at particular interval. After getting I have to remove all annotations and drop new annotations based on the server data. But it looks very inefficient as when we have the annotation for the same user previously exists even then I'm removing and adding the same user annotation. So I want to know can we move the MKAnnotation from one coordinate to other? I have tried "setCoordinate" property but unable to succesfuly implement it. Also it is not "touch and drag" kind. The

I wonder how to set different images to annotation pins on mapview. The difference between the following questions viewForAnnotation confusion and customizing the pinColor iteratively Swift different images for Annotation is that my array of images is generated dynamically with regard to server response. There is no fixed size of the array, so switch/case construction is not a good idea. Moreover, I'm not sure how to apply the solution with custom class aforementioned in topic above. I'm aware that it would be better to post a comment to one of the questions asked before, but unfortunately I'm

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 have a conditional statement to add map annotation icons/pins in the method below. The problem I'm having is that the map is being populated with all the same icon. It should detect the cat id and display the icons depending on which cat id is detected. I'm not sure what the problem is because this did work in iOS 6 and now in iOS 7 the map only displays all the same annotation icon images. - (MKAnnotationView *) mapView:(MKMapView *)mapingView viewForAnnotation:(id <MKAnnotation>) annotation { annView = nil; if(annotation != mapingView.userLocation) { static NSString *defaultPinID = @"";

I have a problem with fitting all my annotations to the screen... sometimes it shows all annotations, but some other times the app is zooming in between the two annotations so that none of them are visible... I want the app to always fit the region to the annotations and not to zoom in between them... what do I do wrong? if ([mapView.annotations count] == 2) { CLLocationCoordinate2D SouthWest = location; CLLocationCoordinate2D NorthEast = savedPosition; NorthEast.latitude = MAX(NorthEast.latitude, savedPosition.latitude); NorthEast.longitude = MAX(NorthEast.longitude, savedPosition.longitude);
