定位CoreLocation

//添加包:CoreLocation.framework

//.plist文件:请求获得应用一直使用定位服务授权，注意使用此方法前要在info.plist中配置NSLocationAlwaysUsageDescription;请求获得应用使用时的定位服务授权，注意使用此方法前在要在info.plist中配置NSLocationWhenInUseUsageDescription,都设置为YES

//CLGeocoder类用于处理地理编码和逆地理编码（又叫反地理编码）功能.

地理编码：根据给定的位置（通常是地名）确定地理坐标(经、纬度)。

逆地理编码：可以根据地理坐标（经、纬度）确定位置信息（街道、门牌等

#pragma mark 根据坐标取得地名(逆地理编码)

-(void)getAddressByLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude{
    //反地理编码

        CLPlacemark *placemark=[placemarks firstObject];

        NSLog(@"%@", placemark.name);//位置名

        NSLog(@"thoroughfare,%@",place.thoroughfare);       // 街道

        NSLog(@"subThoroughfare,%@",place.subThoroughfare); // 子街道
        NSLog(@"locality,%@",place.locality);               // 市
        NSLog(@"subLocality,%@",place.subLocality);         // 区

        NSLog(@"country,%@",place.country);                 // 国家

        //字典形式输出
