我正在使用storyboard在视图控制器中创建地图视图.
@H_502_2@当我使用以下代码时.
userLocation坐标是MapKit.h框架中的预定义值.
现在我创建一个
@H_502_2@在美国加利福尼亚州旧金山绘制一个点.该
- -(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
- {
- CLLocationDistance distance = 1000;
- MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate,distance,distance);
- MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
- [self.mapView setRegion:adjusted_region animated:YES];
- }
userLocation坐标是MapKit.h框架中的预定义值.
现在我创建一个
@H_502_2@这里,显示具有中心坐标的区域.但是,在坐标位置没有绘制点. @H_502_2@如何在该坐标位置绘制点或注释？
- -(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
- {
- CLLocationDistance distance = 1000;
- CLLocationCoordinate2D myCoordinate;
- myCoordinate.latitude = 13.04016;
- myCoordinate.longitude = 80.243044;
- MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(myCoordinate,distance);
- MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
- [self.mapView setRegion:adjusted_region animated:YES];
- }
