我正在使用谷歌 Map 自动填充API自动完成地址由用户键入，一旦我完成所选地址，从谷歌地方自动填充地址传递选定的地址字符串谷歌 Map geocode api，获取详细的组件，问题有时是地理编码API即使autocomplete API返回相同的地址，也不返回街道号码，不知道它出错的地方，下面是我正在使用的代码和两个服务的输出
这就是我从Geocode服务中检索详细地址的方法
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;
}
以下是地址的示例，其中地址具有街道号，但地理编码点返回该地址
{

}
],
"types" : [ "route", "geocode" ]
}
以下是针对上述自动填充地址的Google Map 地理编码API的输出

"partial_match" = 1;
"place_id" = "ChIJV74lHNPCzGoRnS8t_EDR8zk";

}
输出doest具有组件类型“Street number”，其中自动完成的地址字符串在开头就是正确的 . 许多地址都会发生这种情况，可能出现什么问题？还是我需要使用其他服务？具有街道号码的地址的示例如下
这是由自动完成API返回的
{

以下是在将自动完成地址作为输入发送后由Geocode服务返回的结果
results = (

任何帮助将受到高度赞赏 .

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（不是一组功能，如街道，邮编或房子编号） . 服务 tries 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 的结果
您也可以输入 12345 Spring Lane, Wallacedale, Victoria, Australia ，您将获得相同的结果 .
除此之外：我建议request the place-details基于
place_id. 虽然它不能给你想要的结果（房子数），结果应该更精确（绑定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 .
