Създавам приложение за карта в iPhone с помощта на MKMapView.
Успешно намерих моите current location и zoom по този начин по този начин:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.mapView.delegate = self;
self.locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDistanceFilter:kCLDistanceFilterNone];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[self.mapView setShowsUserLocation:YES];
}
-(void) mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views
{
MKAnnotationView *annotationView = [views objectAtIndex:0];
id<MKAnnotation> mp = [annotationView annotation];
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance([mp coordinate], 1550, 1550);
[self.mapView setRegion:region animated:YES];
}
Проблемът, който искам да разреша е:
Имам location на map (този код в viewDidLoad):
CLLocationCoordinate2D location = [self getLocationFromAddressString:@"San Francisco, CA, United States"];
// location.latitude = 37.78608;
// location.longitude = -122.407398;
MapViewAnnotation *mapAnnotation = [[MapViewAnnotation alloc] initWithTitle:@"Store location" coordinate:location];
[self.mapView addAnnotation:mapAnnotation];
а това е mapViewAnnotation:
@implementation MapViewAnnotation
@synthesize title = _title;
@synthesize coordinate = _coordinate;
- (id) initWithTitle:(NSString *) t coordinate:(CLLocationCoordinate2D) c {
self = [super init];
if(self) {
_title = t;
_coordinate = c;
}
return self;
}
@end
Искам да имам подходящи zoomLevel и mapCenter за това location и моето current location.
Бих могъл да направя това успешно в Android с помощта на MapController.zoomToSpan(). Как мога да го поправя в iPhone Map?
