使用MapKit检索UserLocation坐标

Question

我在我的应用程序中使用了MapKit，并用

[mapview setShowUserLocation:YES];

我想用userLocation的坐标来设置region.center.latitude和region.center.longitude，该怎么做？

Answer 1

这是我的答案，我尝试了这样的东西，它是有效的：

//inside my ViewDidLOad
locManager = [[CLLocationManager alloc] init];
[locManager setDelegate:self];
[locManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locManager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation  {

   CLLocationCoordinate2D loc = [newLocation coordinate];
   [maptView setCenterCoordiante:loc];  

}

Answer 2

简单得多：

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.location.coordinate, 1500, 1500);
[mapView setRegion:region animated:YES];
}

Answer 3

出于某种原因，这对我不起作用。它把我带到坐标(0.0000，0.0000)。下面是我的代码，如果你有机会看看它。谢谢你的帮助！

[mapView setMapType:MKMapTypeStandard];
[mapView setZoomEnabled:YES];
[mapView setScrollEnabled:YES];
mapView.showsUserLocation=TRUE;

MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };

CLLocationCoordinate2D myCoord = {mapView.userLocation.location.coordinate.latitude,mapView.userLocation.location.coordinate.longitude};
[mapView setCenterCoordinate:myCoord animated:YES];

region.span.longitudeDelta = 0.01f;
region.span.latitudeDelta = 0.01f;
[mapView setRegion:region animated:YES]; 

[mapView setDelegate:self];
