JPSThumbnailAnnotation is a simple mapkit annotation view for displaying images with clean design and animations. It is 100% programmatically drawn and styled for iOS 7.

JPSThumbnailAnnotation in action

Installation

Manually

Copy the JPSThumbnailAnnotation folder to your Xcode project and link the MapKit, QuartzCore and CoreLocation libraries.

Usage

(see sample Xcode project in /Demo)

You add an JPSThumbnailAnnotation just like any other MKAnnotation. The annotations take in a JPSThumbnail object to display an image, title, subtitle at a specific coordinate. You can also set a block to be run when the disclosure button is tapped.

JPSThumbnail *thumbnail = [[JPSThumbnail alloc] init];
thumbnail.image = [UIImage imageNamed:@"empire.jpg"];
thumbnail.title = @"Empire State Building";
thumbnail.subtitle = @"NYC Landmark";
thumbnail.coordinate = CLLocationCoordinate2DMake(40.75f, -73.99f);
thumbnail.disclosureBlock = ^{ NSLog(@"selected Empire"); };

[mapView addAnnotation:[JPSThumbnailAnnotation annotationWithThumbnail:thumbnail]];

Usage notes

Make sure the mapView implements the following 3 MKMapViewDelegate methods:

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
    if ([view conformsToProtocol:@protocol(JPSThumbnailAnnotationViewProtocol)]) {
        [((NSObject<JPSThumbnailAnnotationViewProtocol> *)view) didSelectAnnotationViewInMap:mapView];
    }
}

- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view {
    if ([view conformsToProtocol:@protocol(JPSThumbnailAnnotationViewProtocol)]) {
        [((NSObject<JPSThumbnailAnnotationViewProtocol> *)view) didDeselectAnnotationViewInMap:mapView];
    }
}

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
    if ([annotation conformsToProtocol:@protocol(JPSThumbnailAnnotationProtocol)]) {
        return [((NSObject<JPSThumbnailAnnotationProtocol> *)annotation) annotationViewInMap:mapView];
    }
    return nil;
}
