iPhone facebook 连接 FQL 查询以获取配置文件 URL

Question

喂。

我正在使用 Facebook Connect FQL 查询来提取我的个人资料照片 url，即 src_big,src_small URL。

但我总是在委托下方得到空数组

• (void)request:(FBRequest*)request didLoad:(id)result

我的 FQL 查询是。

NSString* fql = [NSString stringWithFormat:@"SELECT src_big,src_small FROM photo WHERE pid IN (SELECT cover_pid FROM album WHERE owner =%lld AND name ='Profile Pictures')", session.uid]; NSDictionary* 参数 = [NSDictionary dictionaryWithObject:fql forKey:@"query"]; [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];

但是 - (void)request:(FBRequest*)request didLoad:(id)result 总是返回空结果。

如果有错误请大家指正。

好吧，我错了，我认为你需要一个多查询 + JSON 表示。这是我的代码

    NSString *albumFql = [NSString stringWithFormat:@"SELECT cover_pid, name FROM album WHERE owner =%lld", self.session.uid];
    NSDictionary *fqlsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                    albumFql, @"album",
                                    nil];   
    NSDictionary *params = [NSDictionary dictionaryWithObject:[fqlsDictionary JSONRepresentation] forKey:@"queries"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.multiquery" params:params];
