如何獲得iOS的Facebook相冊？

Question

我正在向Facebook提出以下簡單請求。 我的目標是獲取所有用戶相冊的名稱：

[[AppDelegate sharedDelegate].facebook requestWithGraphPath:@"me/albums" andDelegate:[AppDelegate sharedDelegate]];

然后，我從服務器獲得JSON響應，如下所示：

data =     (
            {
        "can_upload" = 1;
        count = 4;
        "cover_photo" = 321491374598618;
        "created_time" = "2012-06-04T21:46:23+0000";
        from =             {
            id = 100002132746588;
            name = "Owner....";
        };
        id = 321491371265285;
        link = "http://www.facebook.com/album.php?fbid=321491371265285&id=100002132746588&aid=73680";
        name = "Photos";
        privacy = custom;
        type = normal;
        "updated_time" = "2012-06-04T22:08:39+0000";
    },
            {
        "can_upload" = 0;
        count = 1;
        "cover_photo" = 318401854907570;
        "created_time" = "2012-05-31T00:00:35+0000";
        description = "Which Friend Stalks You the Most?";
        from =             {
            id = 100002132746588;
            name = "Owner....";
        };
        id = 318401848240904;
        link = "http://www.facebook.com/album.php?fbid=318401848240904&id=100002132746588&aid=73163";
        name = "Which Friend Stalks You the Most?";
        privacy = friends;
        type = normal;
        "updated_time" = "2012-05-31T00:00:36+0000";
    },

等等。 問題是，當我嘗試用以下方法解析數據時：

NSLog(@"%@", [result objectForKey:@"name"]);

我得到null 。 我假設發生了這種情況，因為返回數據的NSDictionary不知道要關注哪個name條目。 如何解析數據以便獲取所有相冊的名稱？

Answer 1

“result”實際上是一個字典數組，因此循環遍歷數組，然后從數組中的每個元素中獲取名稱。

for (NSDictionary *anAlbum in [result objectForKey:@"data"]) {
    NSLog(@"%@", [anAlbum objectForKey:@"name"]);
}
