iOS根据经纬度获取地址

CLLocation *location = [[CLLocation alloc]initWithLatitude:model.latitude longitude:model.longitude];

//根据经纬度解析成位置
 CLGeocoder *geocoder = [[CLGeocoder alloc]init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemark,NSError *error)
 {
   CLPlacemark *mark = [placemark objectAtIndex:0];
    NSLog(@"city %@ subcity %@",mark.locality,mark.subLocality);
    model.address = [NSString stringWithFormat:@"%@-%@-%@-%@",mark.administrativeArea,mark.locality,mark.subLocality,mark.thoroughfare];
                     [addressArr addObject:model.address];
                     
                     if (addressArr.count == self.tableViewArr.count)
                     {
                         [self.routeLineInfoTabView reloadData];
                     }
                     
                 }];
