1. 在工程里面引入CoreLocation.framework和MapKit.framework。
2. 在.h文件里面加入如下代码：
#import <CoreLocation/CoreLocation.h> #import <MapKit/MKReverseGeocoder.h> #import <MapKit/MKPlacemark.h>@interface RootViewController : UICustomViewController<CLLocationManagerDelegate, MKReverseGeocoderDelegate> { CLLocationManager *gps; }
3. 在.m文件中加入以下代码：
- (void)locationManager:(CLLocationManager *)locationManager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *) oldLocation; { self.location = [NSString stringWithFormat:@"%f,%f",newLocation.coordinate.latitude, newLocation.coordinate.longitude]; [self startedReverseGeoderWithLatitude:newLocation.coordinate.latitude longitude:newLocation.coordinate.longitude]; } - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error { if ( [error code] == kCLErrorDenied ) { [manager stopUpdatingHeading]; } else if ([error code] == kCLErrorHeadingFailure) { } } -(void) startedReverseGeoderWithLatitude:(double)latitude longitude:(double)longitude{ CLLocationCoordinate2D coordinate2D; coordinate2D.longitude = longitude; coordinate2D.latitude = latitude; MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate2D]; geoCoder.delegate = self; [geoCoder start]; } -(void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark { NSString *subthroung=placemark.thoroughfare; NSString *local=placemark.locality; self.textFieldName.text = [NSString stringWithFormat:@"您当前所在位置:%@,%@",local, subthroung]; } -(void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error { }
- (void)viewDidLoad { [super viewDidLoad]; gps = [[CLLocationManager alloc] init]; gps.delegate = self; gps.desiredAccuracy = kCLLocationAccuracyBest; gps.distanceFilter = kCLDistanceFilterNone; [gps startUpdatingLocation]; }
编译运行下就能看到结果了，哈哈～
