Answer 1

实现CLLocationManagerDelegate并编写此函数并在viewController的viewDidLoad方法中调用它.

-(void)startLocationManager
{
    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate=self;
    locationManager.desiredAccuracy=kCLLocationAccuracyBestForNavigation;
    [locationManager startUpdatingLocation];
}

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
 {      
    CLLocationCoordinate2D coordinate = [newLocation coordinate];
    double dblLatitude = coordinate.latitude;
    double dblLongitude = coordinate.longitude;     
 }
