我想根据经纬度找到用户的当前位置。以前我已经使用 MKReverseGeocoder 完成了它,但由于它在 ios5 中已弃用,我使用 CLGeocoder。但无法获取当前位置。
- (void)viewDidLoad
{
locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDistanceFilter:kCLDistanceFilterNone];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
CLLocation *currentLocation = newLocation;
locationLabelOne=newLocation.coordinate.latitude;
locationLabelTwo=newLocation.coordinate.longitude;
geocoder = [[CLGeocoder alloc] init];
[locationManager stopUpdatingLocation];
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
if (error == nil && [placemarks count] > 0) {
placemark = [placemarks lastObject];
NSString *get = [NSString stringWithFormat:@"%@ %@\n%@ %@\n%@\n%@",
placemark.subThoroughfare, placemark.thoroughfare,
placemark.postalCode, placemark.locality,
placemark.administrativeArea,
placemark.country];
} else {
NSLog(@"%@", error.debugDescription);
}
} ];
NSLog(@"%@",placemark);
}
当我 NSLog 地标时,它返回 null。我哪里出错了?
