我正在使用谷歌地图地点自动完成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谷歌地点自动完成地址传递到谷歌地图地理编码API,以获取详细的组件,问题是有时地理编码 API 不会返回街道号码,即使自动完成 API 返回的相同地址有街道号码,也不知道哪里出了问题,下面是我正在使用的代码和两个服务的输出
这就是我从地理编码服务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
{

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就有它。许多地址都会发生这种情况,可能是哪里出了问题?或者我需要使用其他服务吗? 下面是具有街道号码的地址示例
这是由自动完成 API 返回的

任何帮助将不胜感激。
最佳答案
您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(不是街道、邮政编码或门牌号码等一组功能)。该服务尝试找到确切的地点(基于输入),但匹配可能是部分的。
当你例如输入 740 Spring Lane, Wallacedale, Victoria, Australia at http://maps.google.com您将得到Spring Ln, Wallacedale VIC 3303,Australia
的结果您还可以输入 12345 Spring Lane, Wallacedale, Victoria, Australia ,您将得到相同的结果。
除此之外:我建议request the place-details基于 place_id
。虽然它不一定会给你想要的结果(门牌号),但结果应该更准确(绑定(bind)到特定地点而不是某个地点的地址)。它还将返回该地点的更多详细信息。
