iphone - 我可以更快地提出请求吗？ ( Facebook 图形 API)

Question

我编写了以下代码来获取我 friend 的异性信息。
首先，我发送了获取所有 friend ID 的请求。然后我再次发送请求以获取 friend 的信息(姓名、照片等)。
但我有 350 个 friend ，我发送了 350 个请求。花1分钟真的很慢。
我能让这个过程更快吗？

- (void)request:(FBRequest *)request didLoad:(id)result
{
if (request == requestFriends) {
    NSMutableArray *tempKeys = [NSMutableArray array];

    for (NSDictionary *dic in [result objectForKey:@"data"]) {
        [tempKeys addObject:[dic objectForKey:@"id"]];
    }

    NSMutableDictionary *params = [NSMutableDictionary dictionary];

    if ([self.myGender isEqualToString:@"male"]) {
        params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"id,name,gender,age,location", @"field", nil];
    } else if ([self.myGender isEqualToString:@"female"]) {
        params =[NSMutableDictionary dictionaryWithObjectsAndKeys:@"id,name,age,gender,work,school", @"field", nil];
    }

    for (NSString *key in tempKeys) {
        [requestArray addObject: [delegate.facebook requestWithGraphPath:key andParams:params andDelegate:self]];
    }

    i = tempKeys.count;
} else if (request == self.myPicRequest) { //고화질 프로필 사진 받아오는 부분
    NSArray *arr = [result objectForKey:@"data"];
    for (NSDictionary *result in arr) {
        if([[result objectForKey:@"type"]isEqualToString:@"profile"]) {
            profileRequest = [delegate.facebook requestWithGraphPath:[result objectForKey:@"cover_photo"] andDelegate:self]; //프로필의 아이디로 다시 리퀘스트
        }
    }
} else if (request == self.profileRequest) {
    NSURL *url = [NSURL URLWithString:[[[result objectForKey:@"images"] objectAtIndex:3] objectForKey:@"source"]];
    UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
    CGRect rect = CGRectMake(0, 60, 360, 360); //중간부분을 크롭
    [self.candidatePicArray addObject:[self imageByCropping:image toRect:rect]];
    NSLog(@"이미지들어간다");
} else {         
    for (FBRequest *req in requestArray) {
        if (request == req) {
            if (![[result objectForKey:@"gender"]isEqual:myGender]) {
                [candidateIdArray addObject:[result objectForKey:@"id"]];
                [candidateNameArray addObject:[result objectForKey:@"name"]];

                myPicRequest = [delegate.facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/albums", [result objectForKey:@"id"]] andDelegate:self];

                if ([result objectForKey:@"birth"]) {
                [candidateAgeArray addObject:[result objectForKey:@"birth"]];
                }

                if ([result objectForKey:@"Location"]) {
                [candidateLocationArray addObject:[[result objectForKey:@"Location"] objectForKey:@"name"]]; 
                }

                if ([[result objectForKey:@"work"] objectAtIndex:0]) {
                [candidateWorkArray addObject:[[[[result objectForKey:@"work"] objectAtIndex:0] objectForKey:@"employer"] objectForKey:@"name"]];
                }
                NSLog(@"girl!");
            }
            j++;
//                NSLog(@"candidateNameArray : %@", [result objectForKey:@"name"]);
        }
    }
}

NSLog(@"i = %d, j = %d", i , j);
[progressView setProgress:(float)(j/i) animated:YES]; 

if(i == j) {
    [self performSegueWithIdentifier:@"SEGUE_START" sender:nil];
}

SO 上的另一个问题中有一些关于批处理请求的线索:

Batch calls with Facebook Graph API & PHP

虽然它使用 php，但您可能会得到一些线索。
