IOS中使用百度地图定位后获取城市坐标,城市名称,城市编号信息

/**当获取到定位的坐标后，回调函数*/

- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation{

BMKCoordinateRegion region;

region.center.latitude  = userLocation.location.coordinate.latitude;

region.center.longitude = userLocation.location.coordinate.longitude;

region.span.latitudeDelta = 0;

region.span.longitudeDelta = 0;

NSLog(@"当前的坐标是:%f,%f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);

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

[geocoder reverseGeocodeLocation: userLocation.location completionHandler:^(NSArray *array, NSError *error) {

if (array.count > 0) {

CLPlacemark *placemark = [array objectAtIndex:0];

if (placemark != nil) {

NSString *city = placemark.locality;

NSLog(@"当前城市名称------%@",city);

BMKOfflineMap * _offlineMap = [[BMKOfflineMap alloc] init];

_offlineMap.delegate = self;//可以不要

NSArray* records = [_offlineMap searchCity:city];

BMKOLSearchRecord* oneRecord = [records objectAtIndex:0];

//城市编码如:北京为131

NSInteger cityId = oneRecord.cityID;

NSLog(@"当前城市编号-------->%zd",cityId);

//找到了当前位置城市后就关闭服务

[_locService stopUserLocationService];

}

}
