iphone - MGTwitterEngine 和 iPhone

Question

我下载了 MGTwitterEngine 并添加到我的 iPhone 项目中。它正在连接并获取雕像，我可以通过将它们转储到 NSLog 中来判断它们。但是，我不知道如何解析这些调用，以便将它们添加到表中。它们以 NSString 形式返回，如下所示:

      {
    "created_at" = 2009-07-25 15:28:41 -0500;
    favorited = 0;
    id = 65;
    source = "<a href=\"http://twitter.com/\">Twitter</a>";
    "source_api_request_type" = 0;
    text = "The wolf shirt strikes again!! #sdcc :P http://twitpic.com/blz4b";
    truncated = 0;
    user =         {
        "created_at" = "Sat Jul 25 20:34:33 +0000 2009";
        description = "Host of Tekzilla on Revision3 and Qore on PSN. Also, a geek.";
        "favourites_count" = 0;
        "followers_count" = 0;
        following = false;
        "friends_count" = 0;
        id = 5;
        location = "San Francisco";
        name = "Veronica Belmont";
        notifications = false;
        "profile_background_tile" = false;
        "profile_image_url" = "http://blabnow.com/avatar/Twitter_10350_new_twitter_normal.jpg";
        protected = 0;
        "screen_name" = Veronica;
        "statuses_count" = 2;
        "time_zone" = UTC;
        url = "http://www.veronicabelmont.com";
        "utc_offset" = 0;
    };

有人使用过这个可以告诉我其他人如何在他们的项目中使用它吗？

谢谢

您在控制台中看到的是 NSDictionary 的 NSLog，而不是 NSString。来自马特·格梅尔的MGTwitterEngine Readme :

The values sent to these methods are all NSArrays containing an NSDictionary for each status or user or direct message, with sub-dictionaries if necessary (for example, the timeline methods usually return statuses, each of which has a sub-dictionary giving information about the user who posted that status).

因此，您传递给 NSLog() 语句的任何对象实际上都是一个字典，您可以通过调用来访问这些字段:

NSString *createdAtDate = [record valueForKey:@"created_at"];
NSString *source = [record valueForKey:@"source"];
// etc...

其中记录是对象。请记住，user 字段是一个子字典。您可以通过以下方式访问它:

NSDictionary *userDict = [record valueForKey:@"user"];
NSString *name = [userDict valueForKey:@"name"];
NSString *location = [userDict valueForKey:@"location"];
// etc...

您实际上可以使用请求中返回的 NSArray 作为 TableView 的数据源，然后只需通过 -cellForRowAtIndexPath TableView 委托(delegate)中的索引提取所需的数据源。
