Objective-C

// 设置检索的过滤选项
BTKQueryEntityFilterOption *filterOption = [[BTKQueryEntityFilterOption alloc] init];
filterOption.activeTime = [[NSDate date] timeIntervalSince1970] - 700 * 24 * 3600;
// 设置检索结果的排序选项
BTKSearchEntitySortByOption * sortbyOption = [[BTKSearchEntitySortByOption alloc] init];
sortbyOption.fieldName = @"loc_time";
sortbyOption.sortType = BTK_ENTITY_SORT_TYPE_DESC;
BTKDistrictSearchEntityRequest *request = [[BTKDistrictSearchEntityRequest alloc] initWithQueryKeyword:@"海淀区" filter:filterOption sortby:sortbyOption outputCoordType:BTK_COORDTYPE_BD09LL returnType:BTK_ENTITY_SEARCH_RESULT_TYPE_ALL pageIndex:1 pageSize:10 ServiceID:serviceID tag:2];

/**
行政区域内检索Entity终端实体的回调方法

@param response 检索结果
*/
- (void)onEntityDistrictSearch:(NSData *)response {
    NSDictionary *content = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableContainers error:nil];//转换数据格式
    NSLog(@"检索结果：%@",content);
}
