如何使用 FQL 获取高分辨率页面和图片的提要

Question

我正在尝试从像可口可乐这样的页面获取所有提要，并且我想以大分辨率获取此页面的相关图片，但我只有小版本。但我不知道如何直接从提要中获取大版本。

我正在使用 ios-facebook-sdk。

// Get Feed
[_facebook requestWithGraphPath:@"coca-cola/feed" andDelegate:self];

// Get Photo
NSString *req = @"SELECT pid,owner,src_big, object_id FROM photo WHERE aid IN ( SELECT aid FROM album WHERE owner = 40796308305 )";
NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                req, @"query",
                                [_facebook accessToken], @"access_token",
                                nil];
[_facebook requestWithMethodName:@"fql.query"
                       andParams:params
                   andHttpMethod:@"POST"
                     andDelegate:self];

我发现，如果你经过相册，你可以检索高分辨率的照片。

- (IBAction)getPageFeed:(id)sender {
    NSLog(@"[%d] %s", __LINE__, __FUNCTION__);
    // Get Feed
    [_facebook requestWithGraphPath:@"APIID/feed" andDelegate:self];
}

- (IBAction)getGetAlbums:(id)sender {
    NSLog(@"[%d] %s", __LINE__, __FUNCTION__);
    [_facebook requestWithGraphPath:@"APIID/albums" andDelegate:self];    
}

- (IBAction)getAllPhotos:(id)sender {
    NSLog(@"[%d] %s", __LINE__, __FUNCTION__);

    int index = 0;
    int iteration = 0;
    for (id i in [sender objectForKey:@"data"]) {
        if ([[i objectForKey:@"name"] isEqual:@"Wall Photos"]) {
            index = iteration;
        }
        iteration++;
    }
    [_facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/photos", [[[sender objectForKey:@"data"] objectAtIndex:index] objectForKey:@"id"]] andDelegate:self];    
}
