mkannotation

问题 I need to display a MKMapView with more than 4 locations with different Annotations and a route connecting the locations. I have tried to display the multiple locations inside a MKMapView but i still not able to find out on how to connect the locations with a route. I am also trying to get this checked if i have implemented it in a right way. I have created a "CLLocationCoordinate2D" and then added a lat and long similarly for 4 points. I have created a custom object which implements

问题 [_mapView selectAnnotation:sannotation animated:YES]; It appears not always, so I don't understand what's the reason for it.

问题 I have a UITapGestureRecognizer that will hide and show a toolbar over my MKMap when the user taps the Map - simple. However, when the user taps on an MKMapAnnotation, I do not want the map to respond to a tap in the normal way (above). Additionally, when the user taps elsewhere on the map to de-select an MKAnnotation callout, I also don't want the toolbar to respond. So, the toolbar should only respond when there are no MKAnnotations currently in selected state. Nor should it respond when

问题 i'm trying to hide an AnnotationView without touching the pin, is the possible? Thanks! for (id currentAnnotation in self.mapView.annotations) { if ([currentAnnotation isKindOfClass:[MyAnnotation class]]) { } } 回答1: Do you just want to make the callout bubble go away but keep the pin?

问题 I want to change the above blue color callout button to gray. How to do this?? Also is this possible to make whole annotation bubble clickable??? Can anyone suggest me the method. 回答1: You are probably adding the blue button something like this - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ MKPinAnnotationView *annView=(MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"annViewIdentifier"]; if (annView == nil) {

问题 Ive got an app that plots mkannotations (i hope i get my terminology right...its kinda confusing) on a mapview. I have already included the subtitle for when you tap on them. I have been looking online for a way to include the distance in those callouts but im not quite there yet. I ran across two partial solutions and Im wondering if they should be combined. First, I didnt have CoreLocation added to my project, I need it right? To be constantly updating my user location and be able to
