Question

我有一个要求，需要获取正在使用我的应用程序的朋友。与Instagram应用程序相同在Facebook上查找朋友。

我知道这是提供好友列表的代码。

- (void) getFriendName :(id) sender {

        self.modeString = @"friendName";

        NSString * query = [NSString stringWithFormat:@"SELECT name FROM user WHERE uid IN (SELECT uid1 FROM friend WHERE uid2=me())",appDelegate.friendList];
        NSLog(@"query :%@",query);
    //    NSString * query = [NSString stringWithFormat:@"SELECT uid, first_name, last_name, birthday_date, sex, pic_square, current_location, hometown_location FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me()) AND strlen(birthday_date) != 0 ORDER BY birthday_date",appDelegate.friendList];
        NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                        query, @"query",
                                        nil];
        [_facebook requestWithMethodName:@"fql.query"
                               andParams:params
                           andHttpMethod:@"POST"
                             andDelegate:self];
    }

在这些朋友列表中，如何使用我的应用程序仅检索朋友？

Answer 1

如果要在服务器上维护数据，请在服务器端进行Facebook集成。

Answer 2

以下是我一直在使用的查询

    NSString *isAppUser = usesApp ? @"1" : @"0";
NSString *query = [NSString stringWithFormat:@"SELECT uid FROM user WHERE is_app_user = %@ AND uid IN (SELECT uid2 FROM friend WHERE uid1 = me()) LIMIT %d",
                   isAppUser, limit];
FBRequest *request = [FBRequest requestWithGraphPath:@"/fql" parameters:@{@"q":query} HTTPMethod:@"GET"];

您可以删除限制，只需让isAppUser始终为@“1”
