推荐答案

要显示标题和字幕，添加到地图的注释对象必须响应-title和-subTitle消息(在MKAnnotation协议中定义为可选) .

To display title and subtitle your annotation object you add to map must respond to -title and -subTitle messages (defined in MKAnnotation protocol as optional).

您还可以使用MKReverseGeocoder类获取有关给定位置的信息，该类查询基于google的服务并通过其委托返回数据(请参见MKReverseGeocoderDelegate协议).

You can also obtain information about given location using MKReverseGeocoder class that queries google based servises for that and returns data via its delegate (see MKReverseGeocoderDelegate protocol).
