解析检索到的Facebook好友详细信息数据

Question

我使用FQL查询一次检索好友列表:

-(void)fetchSaveUserFriendDetails
{
 NSString* query = [NSString stringWithFormat:@"SELECT uid,name,birthday_date FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())"];

 // Set up the query parameter
  NSDictionary *queryParam = [NSDictionary dictionaryWithObjectsAndKeys:
                                    query, @"q", nil];
 // Make the API request that uses FQL
  [FBRequestConnection startWithGraphPath:@"/fql"
                                     parameters:queryParam
                                     HTTPMethod:@"GET"
                              completionHandler:^(FBRequestConnection *connection,
                                                  id result,
                                                  NSError *error) {
    if (!error)
    {
       NSLog(@"result is %@",result);

       NSArray *resultData = [result objectForKey:@"data"];
       if ([resultData count] > 0) {
       for (NSUInteger i=0; i<[resultData count] ; i++) {
          [self.friendsDetailsArray addObject:[resultData objectAtIndex:i]];
             NSLog(@"friend details are %@",friendsDetailsArray);
     }
   }
 }

        }];
 //Save friends to database stuff
 ..................
}

我得到以下输出:

我已经浏览了Facebook Developers FQL查询的官方文档,但我无法找到如何解析数据.

我尝试了以下方法来解析检索到的数据:

NSString *jsonString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
NSDictionary *jsonValue = [jsonString JSONValue];
NSArray *values = [jsonValue objectForKey:@"friendinfo"];

其中result以JSON格式保存所有朋友数据,但我收到以下错误:

-JSONValue failed. Error is: Unexpected end of input

更新信息

我试图解析所有检索到的数据(最终JSON格式)并将所有Facebook好友详细信息保存到我的数据库.所有检索和保存到数据库部分的实现都是在Facebook同步按钮操作中完成的.

需要一些帮助,任何帮助都非常鼓掌,谢谢:)

更新:

- (void)request:(FBRequest *)request didLoad:(id)result {
        if ([result isKindOfClass:[NSArray class]] && ([result count] > 0)) {
            result = [result objectAtIndex:0];
        }
        friends = [[NSMutableArray alloc] initWithCapacity:1];
        NSArray *resultData = [result objectForKey:@"data"];
        if ([resultData count] > 0) {
            for (NSUInteger i=0; i<[resultData count] && i < 25; i++) {
                [friends addObject:[resultData objectAtIndex:i]];
            }
            [friends retain];
            [tblInviteFriends reloadData];              
        } else {
                UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"No Friends" message:@"You have no friends." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
                [alt show];
                [alt release];
        }
}

并在cellForRowAtIndexPath下面显示数据......

cell.textLabel.text = [[friends objectAtIndex:indexPath.row] objectForKey:@"name"]

定义yourDataArray为a NSMutableArray并将其UITableView用于数据显示

我希望这对你有用...
