我使用以下代码使用以下代码获取地图上特定地点的位置

NSString * urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps/geo?key=%@&output=xml&q=%@",GoogleMapsAPIKey,[placeName stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

结果：

<?xml version="1.0" encoding="UTF-8" ?>
<kml xmlns="http://earth.google.com/kml/2.0"><Response>
  <name>postdam</name>
  <Status>
    <code>200</code>
    <request>geocode</request>
  </Status>
  <Placemark id="p1">
    <address>Potsdam, Germany</address>
    <AddressDetails Accuracy="4" xmlns="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0"><Country><CountryNameCode>DE</CountryNameCode><CountryName>Deutschland</CountryName><AdministrativeArea><AdministrativeAreaName>Brandenburg</AdministrativeAreaName><SubAdministrativeArea><SubAdministrativeAreaName>Potsdam</SubAdministrativeAreaName><Locality><LocalityName>Potsdam</LocalityName></Locality></SubAdministrativeArea></AdministrativeArea></Country></AddressDetails>
    <ExtendedData>
      <LatLonBox north="52.4513968" south="52.3424614" east="13.1866602" west="12.9305414" />
    </ExtendedData>
    <Point><coordinates>13.0586008,52.3969627,0</coordinates></Point>
  </Placemark>
</Response></kml>

但现在我想获取邮政编码的信息。如何使用 maps.google.com 做到这一点？

您不再需要使用 google maps API 密钥来访问此 API。

下面是我昨天编写的一个 PHP 函数，用于在 JSON 中实现这一点

function getCoordinatesFromAddress($address, $lat, $long, $region="US") {
       $json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
       $json = json_decode($json);

       $lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
       $long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
}

由于谷歌地图以美国为中心，只需直接输入邮政编码即可（至少目前如此）

http://maps.google.com/maps/geo?output=xml&q=90210

<AdministrativeArea>
    <AdministrativeAreaName>CA</AdministrativeAreaName>
    <SubAdministrativeArea>
        <SubAdministrativeAreaName>Los Angeles</SubAdministrativeAreaName>
        <Locality>
            <LocalityName>Beverly Hills</LocalityName>
            <PostalCode>
                <PostalCodeNumber>90210</PostalCodeNumber>
            </PostalCode>
        </Locality>
    </SubAdministrativeArea>
</AdministrativeArea>
