推荐答案

在iOS 5+中，使用 CLGeocoder 及其 reverseGeocodeLocation:completionHandler: 方法.

In iOS 5+ use CLGeocoder and its reverseGeocodeLocation:completionHandler: method.

以您为例，您可能对areasOfInterest属性最感兴趣.

In your case, you're probably most interested in the areasOfInterest property.

示例:

CLGeocoder* gc = [[CLGeocoder alloc] init];
double lat, lon; // get these where you will
[gc reverseGeocodeLocation:[[CLLocation alloc] initWithLatitude:lat longitude:lon] completionHandler:^(NSArray *placemarks, NSError *error) {
    for ( CLPlacemark* place in placemarks ) {
        if ( place.region )
            NSLog( @"%@", place.region );
        // throroughfare is street name, subThoroughfare is street number
        if ( place.thoroughfare )
            NSLog( @"%@ %@", place.subThoroughfare, place.thoroughfare );
        for ( NSString* aoi in place.areasOfInterest )
            NSLog( @"%@", aoi );
    }
}];
