ios - CLLocationManagerDelegate 方法未更新

Question

@property (nonatomic,strong) CLLocationManager *locManager;

这是我设置管理器的地方:

-(void) viewDidAppear:(BOOL)animated
{
    self.locManager = [[CLLocationManager alloc] init];
    [_locManager setDelegate:self];
    [_locManager setDesiredAccuracy:kCLLocationAccuracyBest];
    [_locManager setPausesLocationUpdatesAutomatically:NO];
    [_locManager setDistanceFilter:1.0];
    [_locManager startUpdatingLocation];
}

这是我的委托(delegate)方法:

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
    int degrees = newLocation.coordinate.latitude;
    double decimal = fabs(newLocation.coordinate.latitude - degrees);
    int minutes = decimal * 60;
    double seconds = decimal * 3600 - minutes * 60;
    NSString *lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"",
                     degrees, minutes, seconds];
    latLabel.text = lat;
    degrees = newLocation.coordinate.longitude;
    decimal = fabs(newLocation.coordinate.longitude - degrees);
    minutes = decimal * 60;
    seconds = decimal * 3600 - minutes * 60;
    NSString *longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"",
                       degrees, minutes, seconds];
    lonLabel.text = longt;
}

该方法在启动时被调用三次，然后再也没有调用过。 预先感谢您

上述方法已弃用。 请使用这个委托(delegate)

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
 {
    CLLocation* location                            = [locations lastObject];

    latitude                                        = location.coordinate.latitude;
    longitude                                       = location.coordinate.longitude;

   [locationManager stopUpdatingLocation];
    locationManager                                 = nil;
}
