这是移动地图代码像OLA和尤伯杯。意思是当我移动地图时，当时地图引脚被注意到，标记中给出的引脚给出了该特定区域的地址，如城市，州，pincode等，但我只想要这个地址的经度，纬度值在标签。

所以请帮我关于这段代码。我怎样才能获得经度纬度值？

Answer 1

假设您想要的标签是self.addresslbl，改变这个方法：

-(void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated 
{ 
    CLLocation *location = [[CLLocation alloc]initWithLatitude:mapView.centerCoordinate.latitude longitude:mapView.centerCoordinate.longitude]; 
    [self geocode:location]; 
} 

要：

-(void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated 
    { 
     self.addresslbl.text = [NSString stringWithFormat:@"%f, %f", mapView.centerCoordinate.longitude, mapView.centerCoordinate.latitude]; 
    }
