Question

我使用FQL multiquery获取用户的事件。

NSString *eventQuery1 = @"SELECT name, start_time, end_time, location, description, venue, host, eid, privacy FROM event WHERE eid IN ( SELECT eid FROM event_member WHERE uid = me() AND rsvp_status='attending' )";
NSString *eventQuery2 = @"SELECT name, start_time, end_time, location, description, venue, host, eid, privacy FROM event WHERE eid IN ( SELECT eid FROM event_member WHERE uid = me() AND rsvp_status='maybe' )";
NSString *eventQuery3 = @"SELECT name, start_time, end_time, location, description, venue, host, eid, privacy FROM event WHERE eid IN ( SELECT eid FROM event_member WHERE uid = me() AND rsvp_status='declined' )";
NSString *eventQuery4 = @"SELECT name, start_time, end_time, location, description, venue, host, eid, privacy FROM event WHERE eid IN ( SELECT eid FROM event_member WHERE uid = me() AND rsvp_status='not_replied' )";
NSString* fql = [NSString stringWithFormat:
                 @"{\"attending\":\"%@\",\"maybe\":\"%@\",\"declined\":\"%@\",\"not_replied\":\"%@\"}",eventQuery1, eventQuery2, eventQuery3, eventQuery4];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObject:fql forKey:@"queries"];
[_facebook requestWithMethodName:@"fql.multiquery" andParams:params andHttpMethod:@"GET" andDelegate:self];

当我收到活动时，我将它们存储到Core Data。后来当我需要获取信息时（比如事件的图像），我使用'eid'来获取事件的图像。但是我注意到那些“eid”字段与Facebook图形调用返回的字段不匹配。在图表中，我得到了事件的id，并使用它来获取事件图像。

"id": "281780925236476",

我的问题是：如何使用FQL获取图API返回的唯一事件ID？或者我可以使用图形API调用来获得与FQL查询相同的结果：所有事件（可能是批量调用）和所有事件字段。例如，对/ events的图谱API查询不会返回事件的描述。

我正在尝试最大限度地减少来自iOS应用程序的HTTP调用量，并且使用FQL查询似乎就是这样。如果可以实现相同的结果，我更愿意使用Graph API。

Facebook事件的FQL查询为同一事件提供了不同的eid
