如何使用 iOS SDK 移动到 Facebook JSON 响应中的下一页? [英] How to move to the next page in Facebook JSON response using iOS SDK?

问题描述

在 Facebook iOS SDK 中，我可以提出这样的查询:

In Facebook iOS SDK, I can ask for queries like this:

[_facebook requestWithGraphPath:@"me/feed" andDelegate:self];

但 Facebook 经常会给出一个有限的 JSON 响应，其中包含一个 URL，用于请求移动到更早的日期，例如.所以在 JSON 响应中，我将有:

But often Facebook will give a limited JSON response with a URL to be used to request to move to earlier dates, for example. So in the JSON response, I'll have:

data =     ( /*things here... status updates, photos, etc...*/
    );
paging =     {
        next = "https://graph.facebook.com/me/feed?sdk=ios&sdk_version=2&access_token= <something>&until=2010-12-04";
        previous = "https://graph.facebook.com/me/feed?sdk=ios&sdk_version=2&access_token=<something>&since=<something>";
    };

我想知道的是...如何转到上一个 URL?SDK 是否提供了执行此操作的接口?

What I'm wondering is... How do I go to the previous URL? Does the SDK provide an interface to do this?

如果可能的话，我实际上想用 Graph API 来回答，因为 Facebook 目前正在弃用 REST API.

If possible, I actually want answer with Graph API, as Facebook is currently deprecating the REST API.

奖励:如果有人可以解释 Facebook 返回的时间格式.我以 2010-09-13T00%3A25%3A16%2B0000 为例.

BONUS: If anyone can explain the time format that's returned by Facebook. I have 2010-09-13T00%3A25%3A16%2B0000 as an example.

推荐答案

向 Facebook 子类或自身添加方法所需的所有内容

all what you need that add a method to the Facebook subclass or itself

- (void)requestWithURLString:(NSString *)fullURL
               andHttpMethod:(NSString *)httpMethod
                 andDelegate:(id <FBRequestDelegate>)delegate {
    [self openUrl:fullURL params:nil httpMethod:httpMethod delegate:delegate];
}

ps 第二个参数 "httpMethod" 可能总是@"GET" 你可以省略它

ps the second param "httpMethod" may be always @"GET" you can omit it
