ios - 正向地理编码没有给出正确的结果

Question

在某些情况下，我没有得到正向地理编码的正确结果。当我搜索某些地方或酒店时，它会显示其他一些地方或地区的结果。我有以下代码。我研究以下link .我应该放置什么网址才能获得正确的结果。

我们如何实现以下网站中给出的内容

https://developers.google.com/places/webservice/autocomplete

A request for addresses containing "Vict" with results in French:

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Vict&types=geocode&language=fr&key=API_KEY A request for cities containing "Vict" with results in Brazilian Portuguese:

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Vict&types=(cities)&language=pt_BR&key=API_KEY

我已经实现了以下但它没有给出我方面的结果

- (CLLocationCoordinate2D)addressLocation{
     NSError *error = nil;

      //   NSString *lookUpString = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=true", SearchtextField];
       //  NSString *API_KEY=@"AIzaSyB27SkGBzvEYKcxvZ5nmOVWvrA-6Xqf-7A";
        NSString *API_KEY=@"AIzaSyCHcqJcqZbP1XpU-WB4VfRct5hpdgqisSY";
        NSString *lookUpString = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/geocode/json?address=%@&region=np&key=%@", SearchtextField,API_KEY];



        lookUpString = [lookUpString stringByReplacingOccurrencesOfString:@" " withString:@"+"];

        NSData *jsonResponse = [NSData dataWithContentsOfURL:[NSURL URLWithString:lookUpString]];

        NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonResponse options:kNilOptions error:&error];
        NSArray *locationArray = [[[jsonDict valueForKey:@"results"] valueForKey:@"geometry"] valueForKey:@"location"];


        NSString *statusString = [jsonDict valueForKey:@"status"];

          if ([statusString isEqualToString:@"OK"])
        {
                locationArray = [locationArray objectAtIndex:0];

                Str_Latitude= [locationArray valueForKey:@"lat"];
                Str_Longitude= [locationArray valueForKey:@"lng"];

                NSLog(@"LatitudeString:%@ & LongitudeString:%@", Str_Latitude, Str_Longitude);
                /*Google place latitude Longitude*/
                Arr_LatLong = @[Str_Latitude,Str_Longitude];

                [[NSUserDefaults standardUserDefaults] setValue:Str_Latitude forKey:@"Str_Latitude"];
                [[NSUserDefaults standardUserDefaults] setValue:Str_Longitude forKey:@"Str_Longitude"];
                [[NSUserDefaults standardUserDefaults] synchronize];

                GogLatitude = [Str_Latitude doubleValue];
                Goglongitude = [Str_Longitude doubleValue];

                if (Bool_SearchField) {
                    [self getGoogleAddress];
                    Bool_SearchField=FALSE;
                }else{

                }


        }else{

                UIAlertView *alertview =[[UIAlertView alloc] initWithTitle:@"Address not found" message:@"make sure you enter a valid address" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
                  [alertview show];

                   NSLog(@"Something went wrong, couldn't find address");
                  [self.tableView reloadData];
            }

        GogLocation.latitude = GogLatitude;
        GogLocation.longitude = Goglongitude;

        return GogLocation;
    }

When i search for radission in maps.google.com it shows as below

But when i search in my app it shows different locations then what I search

您可以使用 Region Biasing ，这according to wiki , 应该是 NP。因此，请在查询末尾添加 &region=np。

或者您可以使用 Viewport Biasing设置搜索范围。
