我正在使用 google maps places autocomplete API 来自动完成用户输入的地址，一旦我完成了所需地址的选择，将选定的地址字符串从 google places 自动完成的地址传递到 google maps geocode api，以获得详细的组件，问题是有时 geocode API 不返回街道号码，即使自动完成 API 返回的相同地址有它，也不确定哪里出错了，下面是我使用的代码和两个服务的输出

这就是我从地理编码服务中检索详细地址的方式

 NSString* address = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=false",completionText];
    NSString* str = [address stringByReplacingOccurrencesOfString:@","
                                                       withString:@""];
    str = [str stringByReplacingOccurrencesOfString:@" "
                                         withString:@"+"];


    NSURL *requestURL = [NSURL URLWithString:str];
    NSURLRequest *request = [NSURLRequest requestWithURL:(requestURL)];

    //response
    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSError *jsonParsingError = nil;
    NSDictionary *locationResults = [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];

    NSLog(@"%@",locationResults);
    NSDictionary* results = [[locationResults objectForKey:@"results"] objectAtIndex:0];
    NSArray* address_components = [results objectForKey:@"address_components"];


    for (id addr in address_components) {
        NSString *long_name = [addr valueForKey:@"long_name"];
        NSString *short_name = [addr valueForKey:@"short_name"];
        NSString *types = [[addr valueForKey:@"types"] objectAtIndex:0];


        if ([types rangeOfString:@"street_number"].location != NSNotFound)
        {
            streetNum = long_name;
        }
        else if ([types rangeOfString:@"route"].location != NSNotFound)
        {
            streetName = long_name;
        }
        else if ([types rangeOfString:@"locality"].location != NSNotFound)
        {
            suburb = long_name;
        }
        else if ([types rangeOfString:@"administrative_area_level_1"].location != NSNotFound)
        {
            state = short_name;
        }
        else if ([types rangeOfString:@"country"].location != NSNotFound)
        {
            country = short_name;
        }
        else if ([types rangeOfString:@"postal_code"].location != NSNotFound)
        {
            postalCode = short_name;
        }

这是一个地址示例，其中地址具有街道号码但地理编码点返回它

            },
            {
               "length" : 8,

            },
            {
               "offset" : 17,
               "value" : "Wallacedale"
            },
            {

            }
         ],
         "types" : [ "route", "geocode" ]
      }

输出没有组件类型“街道号码”，其中自动完成的地址字符串在开头。很多地址都会出现这种情况，有什么问题吗？或者我需要使用其他服务吗？ 具有街道号码的地址示例如下

这是由自动完成 API 返回的

我们将不胜感激任何帮助。

最佳答案

你在自动完成结果的描述中得到的只是一个字符串，仅此而已(不是一组特征，如街道、 zip 或门牌号)。该服务尝试找到确切的位置(基于输入)，但匹配可能是部分的。

当你例如在 http://maps.google.com 输入 740 Spring Lane, Wallacedale, Victoria, Australia你会得到 Spring Ln, Wallacedale VIC 3303,Australia

您也可以输入 12345 Spring Lane, Wallacedale, Victoria, Australia ，您会得到相同的结果。

除此之外:我建议 request the place-details基于 place_id 。虽然它一定不能给你想要的结果(一个门牌号)，但结果应该更准确(绑定(bind)到一个特定的地方而不是一个地方的地址)。它还将返回该地点的更多详细信息。
