Dies ist der bewegliche Karte Code wie ola und uber. Bedeutet, wenn ich die Karte bewege, zu dieser Zeit wird der Kartenstift bemerkt, der notierte Stift wird mir Adresse des bestimmten bestimmten Bereichs wie Stadt, Staat, Pincode usw. im Etikett gegeben, aber ich will nur den Längen-, Breitengradwert dieser Adresse in Etikett.

also bitte helfen Sie mir über diesen Code. Wie kann ich den Längengrad-Breitenwert erhalten?

Answer 1

Unter der Annahme, dass die Bezeichnung, die Sie self.addresslbl zu wollen, ist, diese Methode ändern:

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

An:

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