我正在使用 Google Place api 在 iphone 中显示位置。我正在使用 ClLocation 管理器类来获取将作为 api 参数传递的设备的当前位置。

但它并非每次在多个设备的不同位置都有效。

有什么帮助吗？？

看一下这个

http://code.google.com/apis/maps/documentation/places/#PlaceSearches

您可以使用普通的 Web 服务，发布请求并获取 XML / JSON 列表

地点搜索请求是以下的 HTTP URL

https://maps.googleapis.com/maps/api/place/search/output?parameters

例如

https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=AddYourOwnKeyHere

获取 JSON 输出为

像这样获取 XML
