ios 苹果原生系统定位 CLLocationManager

 首先要干这些事

 下面的方法亲测可用

 ------------------------------------------------------------

    DNLogFUNC

    //初始化位置管理对象

    _locationManager = [[CLLocationManager alloc] init];

    //请求用户授权

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {

        [_locationManager requestWhenInUseAuthorization];

    }

    //指定定位代理类

    _locationManager.delegate = self;

    _locationManager.distanceFilter = 100;

    //开启定位服务

    [_locationManager startUpdatingLocation];

#pragma  mark ----  CLLocationManagerDelegate

//定位成功  位置更新回调 的协议方法

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations

{

    

    CLLocation *currentLocation = [locations lastObject];

    

    CLLocationCoordinate2D coor = currentLocation.coordinate;

    //维度

    DNLog(@"coor.latitude==%f",coor.latitude);

    //经度

    DNLog(@"coor.longitude==%f",coor.longitude);

//    //地理编码类

//    CLGeocoder *geocoder = [[CLGeocoder alloc] init];

//    //反编码  经纬度点-->地理位置信息

//    [geocoder reverseGeocodeLocation:[locations lastObject] completionHandler:^(NSArray *placemarks, NSError *error) {

//        if (!error) {

//            //取最后一个地址

//            CLPlacemark *placemark = [placemarks lastObject];

//           NSString *cityStr = [NSString stringWithFormat:@"%@",placemark.locality];

////            DNLog(@"cityStr==%@",cityStr);取出定位城市

//            DNLog(@"placemark==%@",placemark.addressDictionary);

//             DNLog(@"placemarks==%@",placemarks);

//

//        }

//    }];

}
