In the showPinDetails: method, you can get the currently selected annotation from the map view’s selectedAnnotations property. That property is an NSArray but since the map view only allows one annotation to be selected at a time, you would just use the object at index 0. For example: – (void)showPinDetails:(id)sender { if (mapView.selectedAnnotations.count == 0) … Read more
There are two ways of detecting user interaction with your annotation view. The common technique is to define a callout (that standard little popover bubble that you see when you tap on a pin in a typical maps app) for your MKAnnotationView. And you create the annotation view for your annotation in the standard viewForAnnotation … Read more
plz use this – (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation { if ([annotation isKindOfClass:[MKUserLocation class]]) return nil; if ([annotation isKindOfClass:[CustomAnnotation class]]) { CustomAnnotation *customAnnotation = (CustomAnnotation *) annotation; MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:@”CustomAnnotation”]; if (annotationView == nil) annotationView = customAnnotation.annotationView; else annotationView.annotation = annotation; //Adding multiline subtitle code UILabel *subTitlelbl = [[UILabel alloc]init]; subTitlelbl.text = @”sri … Read more
When you call addAnnotation or addAnnotations, the map view adds the reference(s) to its internal list of annotations. The annotations property of MKMapView simply returns this internal list (whatever type it might be) as an NSArray. I don’t know of any place in the documentation where it states that the annotations property returns the array … Read more
To create a custom annotation view (your replacement for the standard pin), you can just set the image property of the MKAnnotationView in the viewForAnnotation method: – (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { if ([annotation isKindOfClass:[MKUserLocation class]]) { return nil; } else if ([annotation isKindOfClass:[YourAnnotationClassHere class]]) // use whatever annotation class you used when creating … Read more
Note that there is a method on MKMapView (not MKAnnotationView) for selecting an annotation programmatically that works more or less as you would expect: – (void)selectAnnotation:(id < MKAnnotation >)annotation animated:(BOOL)animated However, it automatically deselects any currently annotation at the same time so this doesn’t solve your problem. Oddly, there is a property on MKMapView that … Read more
Take a look at creating a custom MKAnnotationView object… it is basically a UIView that is tailored for map annotations. In that object you could have your 4 custom labels. In your MKMapViewDelegate class, you implement the viewForAnnotation method: – (CustomMapAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { CustomMapAnnotationView *annotationView = nil; // determine the type of … Read more
In the viewForAnnotation method, you can access your ArtPiece properties but to avoid compiler errors and warnings, you’ll need to first cast the annotation parameter to your custom class. The annotation parameter in that method is just defined as a id<MKAnnotation> so the compiler won’t know about the ArtPiece-specific properties (until you tell it that … Read more
In the showDetails: method, you can get the pin tapped from the map view’s selectedAnnotations array. Even though the property is an NSArray, just get the first item in the array since the map view only allows one pin to be selected at a time: //To be safe, may want to check that array has … Read more
When you want to use your own image for an annotation view, you should create an MKAnnotationView instead of an MKPinAnnotationView. MKPinAnnotationView is a subclass of MKAnnotationView so it has an image property but it generally overrides that and draws a pin image (that’s what it’s for). So change the code to: -(MKAnnotationView *)mapView:(MKMapView *)mV … Read more
