Question

我需要查找Google地方信息。我已经实现了Google地方自动填充功能，并尝试传递区域边界。但它仍然给我的结果不存在于那个边界。

 GMSCoordinateBounds *bounds = [self getGMSBoundsWithRadiusInMeters:20];

GMSAutocompleteFilter *filter = [[GMSAutocompleteFilter alloc] init];
filter.type = kGMSPlacesAutocompleteTypeFilterCity;

GMSPlacesClient *placeClient=[GMSPlacesClient sharedClient];

[placeClient autocompleteQuery:place
                          bounds:bounds
                          filter:filter
                        callback:^(NSArray *results, NSError *error) {
                            if (error != nil) {
                                NSLog(@"Autocomplete error %@", [error localizedDescription]);
                                return;
                            }

                            searchedPlaces=results;

                            UIActionSheet *actionSheet = [[UIActionSheet
                                                                  alloc ]initWithTitle:@"Select Place" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil];

                            for (GMSAutocompletePrediction* result in results) {

                                [actionSheet addButtonWithTitle:[self getPlaceTitle:result.attributedFullText.string]];
                            }
                          [actionSheet showInView:self.view];

                        }];

-(GMSCoordinateBounds*)getGMSBoundsWithRadiusInMeters:(float)radius{
CLLocationCoordinate2D center=CLLocationCoordinate2DMake(28.77, 77.77);


MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(center, radius*2, radius*2);

CLLocationCoordinate2D  northEast = CLLocationCoordinate2DMake(region.center.latitude - region.span.latitudeDelta/2, region.center.longitude - region.span.longitudeDelta/2);
CLLocationCoordinate2D  southWest = CLLocationCoordinate2DMake(region.center.latitude + region.span.latitudeDelta/2, region.center.longitude + region.span.longitudeDelta/2);

GMSCoordinateBounds* bounds = [[GMSCoordinateBounds alloc]
                               initWithCoordinate: northEast
                               coordinate: southWest];

return bounds;
}

但它会返回超出此半径的结果。任何人都可以建议如何在边界内获得结果。

您是否可以通过CLLLocationManager获取userLocation并以这种方式将其传递给GMSPlacesClient

 CLLocationCoordinate2D northEast = CLLocationCoordinate2DMake(_userLocation.latitude + 0.15, _userLocation.longitude + 0.15);
    CLLocationCoordinate2D southWest = CLLocationCoordinate2DMake(_userLocation.latitude - 0.15, _userLocation.longitude - 0.15);
    userBound = [[GMSCoordinateBounds alloc] initWithCoordinate:northEast
                                                      coordinate:southWest];
