定位经纬度解析城市信息 CLGeocoder /CLLocationManager


CLLocationManager使用步骤
1.创建一个CLLocationManager实例
CLLocationManager *locationManager = [[CLLocationManager alloc] init];

2.设置CLLocationManager实例委托和精度
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;

3.设置距离筛选器distanceFilter,下面表示设备至少移动1000米,才通知delegate
locationManager.distanceFilter = 1000.0f;

4.启动请求
[locationManager startUpdatingLocation];

5.停止请求
[locationManager stopUpdatingLocation];

6.解析

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

{

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

    self.geocoder = geocoder;

    [geocoder release];

    [geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {

        NSLog(@"error %@ placemarks count %d",error.localizedDescription,[placemarks count]);

        for(CLPlacemark *placemark in placemarks)

        {

            NSLog(@"address dic %@",placemark.addressDictionary); 

            NSString *localCity = [placemark.addressDictionary objectForKey:@"City"];

            

            [[_mainVC classificationVC] setIsFirstFreshCityData:YES];

            [TopInterface setCLLocationCity:[NSString stringWithString:[localCity substringToIndex:[localCity length]-1]]];

            NSLog(@"定位城市:%@",localCity);

            [TopInterface showToast:@"定位成功,请刷新城市团列表更新商品"];


        }

    }];


    [self.locationManager stopUpdatingLocation];


}
