我正试图从Facebook的一个页面上获取特定专辑的封面照片

for(NSDictionary *album in albums)
         {
             [albumNames addObject:[album objectForKey:@"name"]];
             NSLog(@"%@\n", [album objectForKey:@"id"]);
             [[FBRequest requestWithGraphPath:[NSString stringWithFormat:@"%@/photos", [album objectForKey:@"id"]] parameters:nil HTTPMethod:nil]
              startWithCompletionHandler:
              ^(FBRequestConnection *connection,
                FBGraphObject *albumPhoto,
                NSError *error) {
                  if(!error) {
                      [albumCoverPhotos addObject:[UIImage imageWithData:[[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[[albumPhoto objectForKey:@"data"] objectForKey:@"picture"]]]]];
                  }
              }];
         }
但是，如果（！error）因此
albumCoverPhotos
在此代码末尾为空，则它不会执行
行


我的目标是将页面中所有相册的所有封面图像放入数组
albumCoverPhotos
 所以，这可能是一个错误。放在NSLog之后（错误。本地化描述）；看看它显示了什么错误是200，它起作用了，我在graph API explorer中误读了相册的结构：）
