苹果自带定位获取位置

前言

• 之前项目一直用苹果定位获取经纬度后把经纬度信息传给腾讯地图接口来获取用户位置信息(NSString * location_qq_api_key = @"腾讯给的key字符串";
NSURL * url =[NSURL URLWithString:[NSString stringWithFormat:@"https://apis.map.qq.com/ws/geocoder/v1?coord_type=1&key=%@&location=%f,%f",location_qq_api_key,_bestEffortAtLocation.coordinate.latitude,_bestEffortAtLocation.coordinate.longitude]];)
  导致我一直以为，苹果不能获取街道信息，其实想想苹果既然有自带地图肯定也可以获取详细的位置信息。

代码示例
