[英]Draggable pin on mapview
Hi am trying to create a draggable pin , but it not moving when i try to move the pin only the map moves around and the pin stays at the smae position what mi doing wrong. 嗨,我正在尝试创建可拖动的图钉,但是当我尝试移动图钉时,它不会移动,仅地图会移动,而图钉仍停留在smae位置,这是我做错的。
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
MKPinAnnotationView *test=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"parkingloc"];
if([annotation title]==@"Parked Location")
{
//
[test setUserInteractionEnabled:YES];
[test setCanShowCallout:YES];
[test setDraggable:YES];
return test;
}
[
return test;
}
also my custom annonation class is like these 我的自定义注释类也是这样
- (NSString *)subtitle{
return @"Put some text here";
}
- (NSString *)title{
return @"Parked Location";
}
-(id)initWithCoordinate:(CLLocationCoordinate2D) c{
coordinate=c;
NSLog(@"%f,%f",c.latitude,c.longitude);
return self;
}
- (void)setCoordinate:(CLLocationCoordinate2D)newCoordinate
{
coordinate=newCoordinate;
}
but its not working why...? 但是它为什么不起作用...?
This is old but incase anyone is interested in the future: 这很古老,但以防万一有人对未来感兴趣:
If no |title| 如果没有|标题| is set for the MKPinAnnotationView, dragging won't work either. 为MKPinAnnotationView设置,则拖动也不起作用。
