[self.marker.map clear];
self.marker.map = nil;
反编码（经纬度转成具体位置）：
CLGeocoder *geocoder = [[CLGeocoder alloc]init];
//反地理编码
[geocoder reverseGeocodeLocation:curLocation completionHandler:^(NSArray * _Nullable placemarks, NSError * _Nullable error) {
if (error) {
}else{
CLPlacemark *placemark = [placemarks objectAtIndex:0];//第一个位置是最精确的
//赋值详细地址
DLog(@"placemark---路号name:%@-市locality:%@-区subLocality:%@-省administrativeArea:%@-路thoroughfare:%@",placemark.name,placemark.locality,placemark.subLocality,placemark.administrativeArea,placemark.thoroughfare);
}];
这时候就已经可以获取到具体的国家、省、市、区、街道了。
补充:反编码是获取不到POI位置的（我获取不到）。这时候可以使用
self.placesClient = [GMSPlacesClient sharedClient];//获取某个地点的具体信息
[self.placesClient currentPlaceWithCallback:^(GMSPlaceLikelihoodList *likelihoodList, NSError *error) {
if (error != nil) {
DLog(@"Current Place error %@", [error localizedDescription]);
return;
}
// for (GMSPlaceLikelihood *likelihood in likelihoodList.likelihoods) {
// GMSPlace* place = likelihood.place;
// NSLog(@"Current Place name %@ at likelihood %g", place.name, likelihood.likelihood);
// NSLog(@"Current Place address %@", place.formattedAddress);
// NSLog(@"Current Place attributions %@", place.attributions);
// NSLog(@"Current PlaceID %@", place.placeID);
// }
//这里就可以获取到POI的名字了
//这里做一些你想做的事
}];
点击地图并移动大头针
这里是用到GMSMapViewDelegate的代理回调
回调1：这里是点击地图上的某个点API返回的代理方法，在这个代理方法，你可以获取经纬度去反编译地址
- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate{
//点击一次先清除上一次的大头针
[self.marker.map clear];
self.marker.map = nil;
// 通过location 或得到当前位置的经纬度
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:coordinate.latitude longitude:coordinate.longitude zoom:Level];
CLLocationCoordinate2D position2D = CLLocationCoordinate2DMake(coordinate.latitude,coordinate.longitude);
self.mapView.camera = camera;
//大头针
self.marker = [GMSMarker markerWithPosition:position2D];
self.marker.map = self.mapView;
CLLocation *curLocation = [[CLLocation alloc]initWithLatitude:coordinate.latitude longitude:coordinate.longitude];
CLGeocoder *geocoder = [[CLGeocoder alloc]init];
//反地理编码
[geocoder reverseGeocodeLocation:curLocation completionHandler:^(NSArray * _Nullable placemarks, NSError * _Nullable error) {
if (error) {
DLog(@"error.description:%@",error.description);
}else{
CLPlacemark *placemark = [placemarks objectAtIndex:0];
//赋值详细地址
DLog(@"placemark---路号name:%@-市locality:%@-区subLocality:%@-省administrativeArea:%@-路thoroughfare:%@",placemark.name,placemark.locality,placemark.subLocality,placemark.administrativeArea,placemark.thoroughfare);
}];
}
