CLGeocoder仅返回一个地标 [英] CLGeocoder Only Returning One Placemark

问题描述

我遇到CLGeocoder的问题，当我调用 geocodeAddressString：withCompletionHandler 时，尽管知道输入的字符串应该返回多个值，但我只得到一个结果。类引用甚至指出：

I have a problem with CLGeocoder where when I call geocodeAddressString:withCompletionHandler I only ever get one result back, despite knowing that the inputted string should return more than one value. The class reference even states:

在前向地理编码请求的情况下，如果提供的信息产生多个可能，则可以返回多个地标对象location。

In the case of forward-geocoding requests, multiple placemark objects may be returned if the provided information yielded multiple possible locations.

但是，我的地标数组只有一个项目：

However, my placemarks array only ever has one item in it:

    [geocoderDestination geocodeAddressString:destination completionHandler:^(NSArray *placemarks, NSError *error){
NSLog(@"array count:%i", [placemarks count];}

感谢您的帮助。

我使用了Piccadilly，UK，Union Street，UK之类的字符串，这些字符串只返回了一个结果。现在我想到了，将英国放在最后可能是一个促成因素。

I have used strings such as "Piccadilly, UK", "Union Street, UK" which have only returned one result. Now that I think about it, putting UK on the end might be the contributing factor.

推荐答案

我不知道CLGeocoder，但如果你的要求是位置搜索另一种方式是使用谷歌位置搜索网址 http://maps.google.com/maps/geo?q=london ，它返回包含匹配位置信息的json。

I dont know about CLGeocoder but if your requirement is a location search another way is to use google location search url http://maps.google.com/maps/geo?q=london which returns a json containing the matched location information.
