1.百度地图定位
- 需要调用代理方法设置
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation, 从代理方法里获取当前最新的location.
- 创建
BMKGeoCodeSearch进行反地理编码,记得挂代理<BMKGeoCodeSearchDelegate>
self.getCodeSearch = [[BMKGeoCodeSearch alloc] init];
self.getCodeSearch.delegate = self;
//1.创建反向地理编码选项对象
BMKReverseGeoCodeOption *reverseOption=[[BMKReverseGeoCodeOption alloc]init];
//2.给反向地理编码选项对象的坐标点赋值
reverseOption.reverseGeoPoint=userLocation.location.coordinate;
//3.执行反地理编码
[self.getCodeSearch reverseGeoCode:reverseOption];
- 执行代理方法,获取反地理编码
-(void)onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error
{
BMKAddressComponent *component=[[BMKAddressComponent alloc]init];
component=result.addressDetail;
[self.locationBtn setTitle:[NSString stringWithFormat:@"%@%@", component.streetName?:@"", component.streetNumber?:@""] forState:0];
}
- 补充说明
使用对应的地图获取出来的经纬度,只能使用对应的正向/反向地理编码进行解析, 以上是百度地图解析地理编码的方法
2.系统自带方法
1.设置参数
- (void)reveLocation
{
//定位初始化
CLLocationManager * locationManager=[[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = 10;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager requestWhenInUseAuthorization];
[locationManager startUpdatingLocation];
}
2.实现回调,执行代理方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
//此处locations存储了持续更新的位置坐标值，取最后一个值为最新位置，如果不想让其持续更新位置，则在此方法中获取到一个值之后让locationManager stopUpdatingLocation
CLLocation *currentLocation = [locations lastObject];
// 获取当前所在的城市名
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
//根据经纬度反向地理编译出地址信息
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *array, NSError *error)
{
if (!error)
{
CLPlacemark *place = array.lastObject;
_locationName = place.name;
}
else
{
}
}];
}
3.高德地图
1.设置参数,进行逆地理
- (void)searchReGeocode
{
AMapReGeocodeSearchRequest *regeoRequest = [[AMapReGeocodeSearchRequest alloc] init];
regeoRequest.searchType = AMapSearchType_ReGeocode;
regeoRequest.location = [AMapGeoPoint locationWithLatitude:39.990459 longtitude:116.481476];
regeoRequest.radius = 10000;
regeoRequest.requireExtension = YES;
[self.search AMapReGoecodeSearch: regeoRequest];
}
2.实现回调，获取查询结果：
- (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response
{
NSString *result = [NSString stringWithFormat:@"ReGeocode: %@", response.regeocode];
NSLog(@"ReGeo: %@", result);
}
