    text
    copied!<p>I've got a draggable annotation in IOS4 mapkit, and I'm trying to call an event when the annotation is dragged to a new position.</p> <p>my code currently looks like:</p> <pre><code> - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)annotationView didChangeDragState:(MKAnnotationViewDragState)newState fromOldState:(MKAnnotationViewDragState)oldState { if (newState == MKAnnotationViewDragStateEnding) { CLLocationCoordinate2D droppedAt = annotationView.annotation.coordinate; NSLog(@"dropped at %f,%f", droppedAt.latitude, droppedAt.longitude); //update the annotation //see if its an information annotation if ([annotationView.annotation isKindOfClass:[InfoAnnotation class]]) { NSLog(@"Info annotation updating.."); InfoAnnotation* userAnnotation = ((InfoAnnotation *)annotationView.annotation); [userAnnotation updateLocationWithServerForConvoy: self.title]; } } } </code></pre> <p>the code simply logs the update and then tells the annotation to send its update to my server, which is a custom method.</p> <p>This method seems to be getting fired multiple times, see the log here:</p> <pre><code>2011-06-15 01:12:39.347 Convoy[1699:207] dropped at 37.340206,-122.027550 2011-06-15 01:12:39.347 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:39.658 Convoy[1699:207] dropped at 37.340206,-122.027550 2011-06-15 01:12:39.659 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:39.957 Convoy[1699:207] dropped at 37.340206,-122.027550 2011-06-15 01:12:39.958 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:43.415 Convoy[1699:207] dropped at 37.339251,-122.026691 2011-06-15 01:12:43.416 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:43.713 Convoy[1699:207] dropped at 37.339251,-122.026691 2011-06-15 01:12:43.713 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:44.006 Convoy[1699:207] dropped at 37.339251,-122.026691 2011-06-15 01:12:44.006 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:44.297 Convoy[1699:207] dropped at 37.339251,-122.026691 2011-06-15 01:12:44.297 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:54.825 Convoy[1699:207] dropped at 37.337135,-122.025833 2011-06-15 01:12:54.825 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:55.150 Convoy[1699:207] dropped at 37.337135,-122.025833 2011-06-15 01:12:55.150 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:55.475 Convoy[1699:207] dropped at 37.337135,-122.025833 2011-06-15 01:12:55.476 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:55.771 Convoy[1699:207] dropped at 37.337135,-122.025833 2011-06-15 01:12:55.772 Convoy[1699:207] Info annotation updating.. 2011-06-15 01:12:56.070 Convoy[1699:207] dropped at 37.337135,-122.025833 2011-06-15 01:12:56.070 Convoy[1699:207] Info annotation updating.. </code></pre> <p>Each time I drag it (ie in the gaps) it seems to add 1 to the amount of times it's called.
