使用 Facebook Graph Api 在 iPhone 中解析 News Feed Response

Question

我正在使用 Facebook Graph API...用于获取 facebook 个人资料的新闻源数据..

这是我在控制台中得到的响应

    {
    application =         {
        id = 2309869772;
        name = Links;
    };
    "created_time" = "2011-02-10T09:44:27+0000";
    from =         {
        id = 1845195019;
        name = "Paritosh Raval";
    };
    icon = "http://static.ak.fbcdn.net/rsrc.php/v1/yD/r/aS8ecmYRys0.gif";
    id = "1845195019_192144087475935";
    likes =         {

        data =             (

                id = 1845195019;
                name = "Paritosh Raval";
            }
        );

        }
    );
    type = link;

    type = video;
    "updated_time" = "2011-02-02T04:18:22+0000";
}

，我想在控制台中显示组织结构中的每个数据。谁能帮我解决这个问题吗？

目前尚不清楚你到底在问什么，但我尝试回答。

首先，您需要在方法中解析此响应
- (void)request:(FBRequest *)request didLoad:(id)Facebook iOS SDK

结果可以是一个字符串，如果有多个结果，则可以是 NSArray 和 NSDictionary

在控制台输出中，我们可以看到 NSDictionary 包含数组和字典。
我几乎没有关于它的教程，但它只有俄语版，而且今天网站瘫痪了:(所以我只是从我的文章中复制一个例子。

假设我们想知道 facebook 用户喜欢什么，

- (IBAction)getUserInfo:(id)sender {
  [_facebook requestWithGraphPath:@"me/likes" andDelegate:self];
}

如果我们在浏览器中尝试这个 Graph API 响应或输出到控制台我们可以看到这个请求返回的内容。它返回带有一个且唯一的键“data”的字典以及与该键对应的数组，该数组再次包含键-
«名称»，“类别”，“id”，“创建时间”。不要忘记之前请求“user_likes”权限。
所以我们有这样的解析方法：

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]) {
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
        [self.label setText:@"Photo upload Success"];
    } else if ([result objectForKey:@"data"]){
        NSArray *likes = [result objectForKey:@"data"];
        NSString *text=@"You don't like Steve";
        for (NSDictionary* mylike in likes) {
            NSString *mylikeName = [mylike objectForKey:@"name"];
            if ([mylikeName isEqualToString:@"Steve Jobs"]) {
                text=@"You like Steve";
                break;
            }
        }
        [self.label setText:text];
    }
};

您可以以相同的方式解析结果并填充对象的变量，然后使用它在 TableView 中显示信息。祝你好运！
