Map drag pin

[funkyspider]

Has anyone found out how to move an annotation pin with the MapKit.

I've come across this with a downloadable project but found it doesn't work unfortunately - sometime the pin wont drag, sometimes I get multiple pins where it drags one and leaves the other etc.

Hollow Out: MapKit annotation drag and drop with callout info update


What I'm after is allowing the user to find their current location, drawing a pin rather than the standard blue marker, but want them to be able to move the pin for better accuracy. Current location and a annotation pin etc is no problem, it's just moving the pin.

MKPinkAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:[annotation title]];

pin.animatesDrop = YES;
pin.canShowCallout = YES;
pin.draggable = YES;

continue your coding from there forth

You can add other images in place of the pin. Look here

Huh. Our company's navigation app is written to support iOS 3.0 (The soon-to-be-released update will move that up to 3.2). Thus I had to implement pin dragging without that property, which was added in iOS 4. I didn't know about it though, since I never revisited that code since our approach works.

The way I did it was to create a custom subclass of MKAnnotationView that implements touchesBegan/touchesMoved/touchesEnded. In those methods I figure out the change in location, and update the annotation object on touchesEnded.

To the OP, note that the docs on the draggable property say:

Setting this property to YES makes an annotation draggable by the user. If YES, the associated annotation object must also implement the setCoordinate: method. The default value of this property is NO.
