ios - Google map 地址自动完成和地理编码 API 返回差异地址
<p><p>我正在使用谷歌地图的地方自动完成 API 来自动完成用户键入的地址，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方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，即使自动完成 API 返回的地址相同，geocode API 也不会返回街道号码，不确定哪里出错了，下面是我正在使用的代码和两个服务的输出</p>
<p>这就是我从地理编码服务中检索详细地址的方式</p>
<pre><code> NSString* address = ;
NSString* str = [address stringByReplacingOccurrencesOfString:@","
withString:@""];
str = [str stringByReplacingOccurrencesOfString:@" "
withString:@"+"];
NSURL *requestURL = ;
NSURLRequest *request = ;
//response
NSData *response = ;
NSError *jsonParsingError = nil;
NSDictionary *locationResults = ;
NSLog(@"%@",locationResults);
NSDictionary* results = [ objectAtIndex:0];
NSArray* address_components = ;
for (id addr in address_components) {
NSString *long_name = ;
NSString *short_name = ;
NSString *types = [ objectAtIndex:0];
if (.location != NSNotFound)
{
streetNum = long_name;
}
else if (.location != NSNotFound)
{
streetName = long_name;
}
else if (.location != NSNotFound)
{
suburb = long_name;
}
else if (.location != NSNotFound)
{
state = short_name;
}
else if (.location != NSNotFound)
{
country = short_name;
}
else if (.location != NSNotFound)
{
postalCode = short_name;
}

<p>输出没有组件类型“街道编号”，其中自动完成的地址字符串在开头就正确。许多地址都会发生这种情况，有什么问题吗？还是我需要使用其他服务？
具有门牌号的地址示例如下 </p>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>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(不是一组特征，如街道、 zip 或门牌号)。服务<strong>尝试</strong>找到确切的位置(基于输入)，但可能部分匹配。 </p>
<p>当你例如在 <a href="http://maps.google.com" rel="noreferrer noopener nofollow">http://maps.google.com</a> 输入 <strong><em>740 Spring Lane, Wallacedale, Victoria, Australia</em></strong>您将获得 <strong><em>Spring Ln, Wallacedale VIC 3303,Australia</em></strong></p> 的结果
<p>您也可以输入 <strong><em>12345 Spring Lane, Wallacedale, Victoria, Australia</em></strong>，您会得到相同的结果。</p>
<p>除此之外:我建议 <a href="https://developers.google.com/places/documentation/details#PlaceDetailsResults" rel="noreferrer noopener nofollow">request the place-details</a>基于 <code>place_id</code> 。虽然它不能给你想要的结果(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)。它还会返回该地点的更多详细信息。</p></p>
