设置委托 CLLocationManagerDelegate

#import <CoreLocation/CoreLocation.h>

CLLocationManager *locationManager;
CLLocation *startLocation;


- (void)viewDidLoad 
    [super viewDidLoad];
    NSString *currentLatitude;
    NSString *currentLongitude;
    locationManager = [[CLLocationManager alloc] init];
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.delegate = self;
    [locationManager startUpdatingLocation];
    startLocation = nil;
 

-(void)locationManager:(CLLocationManager *)manager
   didUpdateToLocation:(CLLocation *)newLocation
          fromLocation:(CLLocation *)oldLocation

    currentLatitude = [[NSString alloc] 
                   initWithFormat:@"%g", 
                   newLocation.coordinate.latitude];



    currentLongitude = [[NSString alloc] 
                    initWithFormat:@"%g",
                    newLocation.coordinate.longitude];

   NSLog(@"%@",currentLatitude);
   NSLog(@"%@",currentLongitude);


-(void)locationManager:(CLLocationManager *)manager 
  didFailWithError:(NSError *)error

    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"ERROR" message:[NSString stringWithFormat:@"%@",error] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    [alert release];
