IOS百度地图获取所在的城市名称

            笔者的app要实现定位所在省和城市名称，借此总结巩固一下！

           

@interface VenueListVC : BasePageTableViewVC<BMKLocationServiceDelegate,BMKGeoCodeSearchDelegate> {
    BMKLocationService *_locService;
    BMKGeoCodeSearch *_geoSearch;
    float _curLatitude, _curLongitude;
    NSString *_curCityName,*_curProName;

- (void)viewDidLoad {
    //百度地图定位
    if (![CLLocationManager locationServicesEnabled]) {
        [UIAlertView showMsg:@"请在“系统设置”中开启定位服务" cancelText:@"确定" cancelAction:^{
            [self onBackButtonClick:nil];
        } okText:nil okAction:nil];
        return;
    }
    
    //初始化BMKLocationService
    if (_locService == nil) {
        _locService = [[BMKLocationService alloc]init];
    }
    _locService.delegate = self;
    //启动LocationService
    [_locService startUserLocationService];
    
    _geoSearch = [[BMKGeoCodeSearch alloc] init];
    //编码服务的初始化(就是获取经纬度,或者获取地理位置服务)
    _geoSearch.delegate = self;//设置代理为self
    //    [self showProgressHUDWithText:@"正在定位..."];
    
｝

//反向地理编码
-(void)onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error
{
    if (error == 0) {
        BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init];
        item.coordinate = result.location;
        item.title = result.address;
        NSString* titleStr;
        NSString* showmeg;
        titleStr = @"反向地理编码";
        showmeg = [NSString stringWithFormat:@"%@",item.title];
        _curCityName = result.addressDetail.city;
        _curProName = result.addressDetail.province;
        NSLog(result);
        }

}

//处理位置坐标更新
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation
{
    [_locService stopUserLocationService];
    
    CLLocationCoordinate2D coor;
    coor=userLocation.location.coordinate;
    _curLatitude = coor.latitude;
    _curLongitude = coor.longitude;

    CLLocationCoordinate2D pt = (CLLocationCoordinate2D){_curLatitude, _curLongitude};
    BMKReverseGeoCodeOption *reverseGeocodeSearchOption = [[BMKReverseGeoCodeOption alloc]init];
    reverseGeocodeSearchOption.reverseGeoPoint = pt;
    [_geoSearch reverseGeoCode:reverseGeocodeSearchOption];
    
    
}

/**
 *定位失败后，会调用此函数
 *@param error 错误号
 */
- (void)didFailToLocateUserWithError:(NSError *)error {
    [_locService stopUserLocationService];
    [self hideProgressHUD];
}
