ios – 如何访问MKMapItem的类别或类型

概述我正在编写一个使用MapKit的应用程序.我已经实现了MKLocalSearch,我得到了一个MKMapItem数组.但是我想知道是否可以获得这些项目的类别.例如,在地图应用程序中,为商店,酒店,火车站等显示了不同的图标.此外,如果您查看地点标记.您将获得一个类别标签,如Grocery.作为开发人员,我可以访问Map项目的信息吗？如果是这样,我想知道如何. 谢谢 是的,您可以获得此信息.有关搜索位 我正在编写一个使用MapKit的应用程序.我已经实现了MKLocalSearch,我得到了一个MKMAPItem数组.但是我想知道是否可以获得这些项目的类别.例如,在地图应用程序中,为商店,酒店,火车站等显示了不同的图标.此外,如果您查看地点标记.您将获得一个类别标签,如Grocery.作为开发人员,我可以访问Map项目的信息吗？如果是这样,我想知道如何.

谢谢

解决方法 是的,您可以获得此信息.有关搜索位置的详细信息,请参阅以下方法.

我担心您只能从MKPlacemark获取地址详细信息.

现在您需要做的是,从MKPlacemark获取地址详细信息,您需要获得任何开源API的帮助,这些API可以帮助您将地址分类为某些标签/注释.

其中一个很好的API是Mapbox,但遗憾的是它已付费.

因此,从第三方API,您可以进行神​​奇的搜索.我没有搜索API / WebService,但它应该在那里.
