iOS通過經緯度反向解析地址

1. 在工程裡面引入CoreLocation.framework和MapKit.framework。

2. 在.h文件裡面加入如下代碼：

1. #import <CoreLocation/CoreLocation.h>
2. #import <MapKit/MKReverseGeocoder.h>
3. #import <MapKit/MKPlacemark.h>

1. @interface RootViewController : UICustomViewController<CLLocationManagerDelegate, MKReverseGeocoderDelegate> {
2. CLLocationManager *gps;
3. }

3. 在.m文件中加入以下代碼：

1. - (void)locationManager:(CLLocationManager *)locationManager didUpdateToLocation:(CLLocation *)newLocation
2. fromLocation:(CLLocation *) oldLocation;
3. {
4. self.location = [NSString stringWithFormat:@"%f,%f",newLocation.coordinate.latitude, newLocation.coordinate.longitude];
5. [self startedReverseGeoderWithLatitude:newLocation.coordinate.latitude longitude:newLocation.coordinate.longitude];
6. }
8. - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
9. if ( [error code] == kCLErrorDenied ) {
10. [manager stopUpdatingHeading];
11. } else if ([error code] == kCLErrorHeadingFailure) {
13. }
14. }
16. -(void) startedReverseGeoderWithLatitude:(double)latitude longitude:(double)longitude{
17. CLLocationCoordinate2D coordinate2D;
18. coordinate2D.longitude = longitude;
19. coordinate2D.latitude = latitude;
20. MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate2D];
21. geoCoder.delegate = self;
22. [geoCoder start];
23. }
25. -(void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
26. {
28. NSString *subthroung=placemark.thoroughfare;
29. NSString *local=placemark.locality;
30. self.textFieldName.text = [NSString stringWithFormat:@"您當前所在位置:%@,%@",local, subthroung];
32. }
33. -(void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
34. {
35. }

1. - (void)viewDidLoad {
2. [super viewDidLoad];
4. gps = [[CLLocationManager alloc] init];
5. gps.delegate = self;
6. gps.desiredAccuracy = kCLLocationAccuracyBest;
7. gps.distanceFilter = kCLDistanceFilterNone;
8. [gps startUpdatingLocation];
9. }

編譯運行下就能看到結果了，哈哈～
