Answer 1

最后，想通了。这就是我所做的。

NSString * query = [NSString stringWithFormat：@＆＃34; SELECT pid，object_id，src_big，src_big_width，src_big_height FROM photo WHERE object_id =％@＆＃34;，wallPost [@＆＃34; object_id＆＃34;] ]。 //从SELECT ........

开始

    NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                    query, @"q",
                                    nil];

[FBRequestConnection startWithGraphPath：@＆＃34; / fql＆＃34;参数：params HTTPMethod：@＆＃34; GET＆＃34; completionHandler：^（FBRequestConnection *连接，                                                                                                                 id结果，                                                                                                                 NSError *错误）{             //做你的东西             if（！error）{                 NSArray * photo = [result objectForKey：@＆＃34; data＆＃34;];

             NSString *photoString = [[photo valueForKey:@"src_big"]componentsJoinedByString:@""];
             //NSLog(@"result %@ %@", photoString);

        }
    }];
