CLlocation 的地理位置编码

//创建地理编码对象    CLGeocoder *geocoder=[[CLGeocoder alloc]init];    //创建位置    CLLocation *location=[[CLLocation alloc]initWithLatitude:userLocation.location.coordinate.latitude longitude:userLocation.location.coordinate.longitude];        //反地理编码    [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray* _Nullable placemarks, NSError * _Nullable error) {

//判断是否有错误或者placemarks是否为空

if (error !=nil || placemarks.count==0) {

NSLog(@"%@",error);

return ;

}

for (CLPlacemark *placemark in placemarks) {

//赋值详细地址

annotoation.title = [NSString stringWithFormat:@"%@%@",placemark.administrativeArea,placemark.locality];

annotoation.subtitle  =[NSString stringWithFormat:@"%@%@",placemark.subLocality,placemark.name];

}

}];
