带有边界的iOS GMSAutoComplete结果(iOS GMSAutoComplete result with in boundaries)

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，并试图通过区域边界。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。

I need to find out Google Places with in boundary. I have implemeted Google place autocomplete and tried to pass bounds for region. But it still gives me result that are not present in that boundaries.

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; }

But it returns result that are beyond this radius. Can anyone suggest how to get result with in the boundaries.

最满意答案

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];

I am not sure if iOS SDK provides any option for providing radius boundary in their Google Place SDK. But I have resolved it by implementing their web API for near by search at my PHP backend.

This helps me to filter out results based on my radius.
